Nestled in the lush landscape, a modern reinterpretation of a once-fallen barn now features a charming guest cottage with stylish details and contemporary amenities. Situated along a narrow lot in Germantown, New York, the cottage completes a cluster of existing buildings, forming an intimate courtyard on one side. Steel effect folding patio doors fully open the living areas to the expansive fields and the Catskill Mountains beyond. The homeowners, a young family with parents living abroad, envisioned a cozy yet modern ADU for extended stays. Designed by Lauren Cawse, AIA, architect and partner at The Art of Building, the year-round retreat draws inspiration from traditional local barns while embracing a seamless indoor-outdoor connection. Captivating Guest Cottage Design Enhances the Senses with Steel Effect Folding Patio Doors The modern ADU design started with the site itself. Positioned between residential and commercial neighbors, the elongated property required a careful balance of privacy and openness. Architect Lauren Cawse approached the layout by redefining the existing house and garage as the east and west sides of an outdoor room, with the new cottage forming its southern boundary. This arrangement created a clear courtyard near the main residence while directing the 800-square-foot guest house toward the open meadow and the distant Catskill Mountains. “The unique character of the site and its history inspired the architectural direction,” says Cawse. “The intent was to create a secondary structure in the compound in clear contrast to the modern farmhouse style of the house and garage.” A Barn-Inspired Exterior Adds Visual Flair The exterior envelope evokes a traditional barn with a simple gable shape, weathered wood siding, cedar shingles, and a foundation veneer made of local fieldstone. A large sliding barn door adds a complementary feature to the courtyard-facing side, creating a dynamic opening that maintains uninterrupted views through the cottage to the meadow beyond. Steel effect folding patio doors surrounding the structure add a modern touch of transparency, and simulated divided lites allow the contemporary glass wall systems to harmonize with the traditional elements of the modern ADU design. “The goal was to fully open the living areas to the outdoors, framing views to the meadows and mountains,” says Cawse. “The positioning of the NanaWall systems frames the views and, when open, dissolves the boundary between inside and out.” Interior Design That Mirrors Nature’s Tranquility Inside, the design program features a simple layout with one bedroom, a full bath, a kitchenette, and a living area with a wood-burning stove. The interior, a collaboration between The Art of Building and the homeowners, is defined by an understated palette and tactile materials that reflect the natural setting. Color is introduced through the framed glass views on all sides of the structure. Reclaimed timber collar ties span the ceiling overhead, while stone surfaces and naturally patinated metal accents add quiet texture throughout. Custom hand-painted Delft tiles along the kitchen backsplash add personal detail, and terra cotta flooring in the bathroom brings warmth and old-world charm. Soaring ceilings and abundant daylight create a peaceful play of light and shadow, shifting subtly with the seasons and emphasizing the cottage’s connection to the natural landscape outside. Sleek Steel Effect Folding Patio Doors Elevate the Modern ADU Design Aesthetic Three customized steel effect folding patio doors define the living space, each aligned to respond to a different edge of the site. The largest, spanning nearly 20 feet wide and just under eight feet tall, opens directly onto the stone patio, allowing the main gathering area to extend fully into the landscape. Along the side of the living room, a smaller 10-foot-wide system introduces more light and ventilation, nearly creating an open corner condition if not for the structural post that supports the façade and roofline. At the rear, a fourth ten-foot-wide system features a French door swing panel configuration that opens toward the courtyard, strengthening the design connection to the main residence. All steel effect folding patio doors were specified with a low-maintenance, water-rated Performance Sill to safeguard against inclement weather while providing a seamless, barrier-free transition to the outdoor patio. Unique Customizations for Visual Appeal and a Steel Effect Each folding patio door system is configured to open outward, maximizing usable floor space in the compact interior and allowing furniture placement to remain uninterrupted. By stacking outward, the steel effect folding patio doors, specified in a SE Classic Bronze powder coat, ensure every inch of the cottage is optimized. Simulated divided lites create a consistent rhythm across windows and doors, maintaining alignment with the traditional barn-inspired exterior. In the bedroom, a three-panel, 10-foot-wide system mirrors these customizations, matching the steel effect divided-lite pattern and outward-opening configuration, extending the indoor-outdoor connection while preserving visual continuity throughout the ADU. “The divided lites were crucial to the architectural vision, and while budget prohibited a steel and glass system, NanaWall Systems’ thin frames provide the open and airy feeling we hoped to attain,” says Cawse. “Simulated divided lites transition the thoroughly modern element of the glass walls to remain in harmony with the otherwise traditional palette.” Matching Windows and Doors: Create a Cohesive Design Program Alongside the larger openings in the living areas and bedroom, a smaller 3-foot-tall NanaWall tilt turn window was added to the bathroom. This window-sized NanaWall system perfectly matches the divided lite panels and sleek frames of the steel effect folding patio doors, creating a cohesive modern ADU design throughout. The compact opening provides ventilation and natural light, enhancing the spa-like atmosphere along with natural stone flooring. The matching glass lines and sleek profiles of the NanaWall Generation 4 comprehensive product line further unify visual consistency, allowing each system to fit into the architectural style seamlessly. “This project had three bifold glass walls, a pair of double French doors with sidelites, and a single tilt turn window,” says architect Lauren Cawse. “Being able to work with a single manufacturer provided aesthetic cohesiveness and simplified coordination.” Sustainability Where It Matters Most New York weather can vary from hot 85-degree summers to cold 26-degree winters. Creating an efficient living space was a primary goal. To achieve this, the design included Timber HP-insulated walls and floors with a heat pump system for effective heating and cooling. Additionally, the steel effect folding patio doors and windows were specified with double-glazed panels to ensure a tight building envelope. Indoor-Outdoor Living Spaces for Relaxing and Entertaining In-house landscape designer Liz Pulver worked closely with the team to conceive open-air spaces that enhanced the connection between inside and outside. To the south end of the lot, the landscape transitions into an “enhanced meadow,” allowing the cottage to feel embedded within the surrounding fields rather than set apart from them. A circular pool was designed to mimic a natural pond with a modest footprint. Around it, a minimalist fence and sunken stone ha-ha wall offer discreet safety for young children. Limited space due to existing infrastructure and zoning setbacks left only a small footprint for the swimming pool, prompting the designer to propose a circular form that maximized the usable swimming area. “We felt that the perfect way to integrate a pool into the property and to honor the landscape would be to treat the pool as a piece of art itself,” says Pulver. “The result is a beautiful round pool that serves as both a functional retreat and a sculptural moment.” Final Thoughts: A Barn-Inspired Design for Contemporary Living This modern ADU design skillfully combines modern features with the enduring charm of traditional barns. The outcome is a welcoming living space that stands out amid a stunning landscape. Natural materials that mimic the beauty of the outdoors, expansive steel effect folding patio doors that fill the space with fresh air and natural light, and a restrained interior design work together to create an inviting retreat for everyday living, throughout the seasons. “When entering the site, the cottage feels as though it was always there,” says Cawse. “It achieves its two opposing goals by creating a feeling of intimacy and enclosure near the house while also functioning as a threshold to the expansive fields and views beyond.” Explore how NanaWall folding patio doors elevate other ADU spaces in our inspiring project photo gallery!

Originally built in 1892, this quaint log cabin has undergone a transformative renovation while preserving its charming character. Located near the Little Deschutes River in Central Oregon, within the historic Vandert Homestead, the home now boasts bright, open spaces for everyday living, complete with flexible aluminum clad folding doors. Working alongside contractor Bales Inc., architect Jeff Klein from Klein Architecture led the renovation with the goal of opening the once dark interior to natural light and the surrounding landscape. Central to the design was transforming a deteriorating garage into a new functional sunroom, creating a light-filled space that reorients the cabin design toward the patio and natural environment. Restoring a Historic Cabin with Aluminum Clad Folding Doors outdoor living with aluminum clad folding door A Revamped Cabin Design for Indoor-Outdoor Living The former garage is now a transitional space between the cabin and a natural stone patio. Positioned along the south elevation, the sunroom captures daylight throughout the day while acting as a buffer between the interior and exterior environments. A revised roof assembly was developed to resolve previous drainage failures. Working with framers, the design team incorporated a sloping roof system with a waterproof membrane to direct water away from the structure. This approach not only protected the log walls but also created access to a rooftop deck from the upper level, adding functional outdoor space without expanding the building footprint. “It was also critical to transform the existing dark, segmented interior spaces by physically opening them up to the new sunroom,” says Klein. “NanaWall systems offered the ideal solution for what we were after.” historical homestead interior Improving Spatial Flow, From the Kitchen to the Sunroom The kitchen remained largely intact during the renovation, retaining many of the elements that had defined the cabin’s character for decades. Features such as the farmhouse sink, concrete countertops, butcher-block island, and built-in seating were retained, creating a perfect blend of old and new. What changed was how the kitchen connects to the surrounding rooms. The layout now flows naturally into an adjacent dining area before extending into the newly added sunroom, delivering a seamless transition from the interiors to the outdoors through aluminum clad folding doors. Historic log cabin with clad folding doors and windows A Light-Filled Sunroom Designed for Gatherings with Aluminum Clad Windows and Doors The newly added sunroom became the centerpiece of the cabin design. Designed as a bright, welcoming space, it connects the historic cabin to the natural stone patio beyond. Interior designer Sue Olson helped create the room's atmosphere by choosing finishes and furnishings that complement the cabin's rustic materials while keeping the space open and inviting. The sunroom captures sunlight throughout the day and serves as a flexible space for dining, relaxing, and entertaining. The addition was designed to sit comfortably alongside the existing log structure while introducing expansive glazing and aluminum clad folding doors that draw daylight deep into the home. NanaWall aluminum clad folding doors and windows Aluminum Clad Folding Doors Open the Sunroom to the Patio A NanaWall aluminum clad folding glass door opens the south wall of the sunroom, creating a direct connection to the natural stone patio. Spanning more than thirteen feet wide and nearly eight feet tall, the system allows the entire façade to open when the panels are folded back. Specified with pine wood frames and simulated divided lites, the door complements the cabin’s traditional materials while introducing the flexibility of modern indoor-outdoor living. When closed, the door frames the view while bringing daylight into the sunroom. When open, the space seamlessly flows into the patio. Plus, customized with double glazed panels, these aluminum clad systems offer an insulated barrier that keeps cold weather out and keeps comfortable interiors year-round. “The NanaWall system was the ideal solution for the proposed design,” says Klein. “The result is a seamless connection between the sheltered interior area and the openness of the outdoor environment.” aluminum clad folding windows A Folding Window Creates an Indoor-Outdoor Bar Complementing the folding door and indoor-outdoor cabin design, a NanaWall aluminum clad folding window was installed at bar height along the sunroom wall facing the patio. Stretching more than thirteen feet across and just over four feet in height, the opening transforms the wall into a casual indoor-outdoor serving counter. Specified with matching pine wood frames and simulated divided lites, the system folds away easily, creating an indoor-outdoor bar that encourages interaction between the sunroom and patio. When open, the counter becomes a flexible gathering point for meals, drinks, and conversation, allowing those inside and outside to share the space comfortably. “The NanaWall door and window systems played a pivotal role in achieving our design objectives,” says Klein. “The connection between the indoor and outdoor environment has become seamless.” inoor-outdoor living with clad folding windows and doors The Flexible Design Solution for Every Home Style Beyond creating large openings, the NanaWall aluminum clad folding doors were chosen for how well they integrate with the cabin’s traditional architecture while delivering modern functionality. The wood clad panels, specified with simulated divided lites, reflect the style and charm of classic window detailing, while panels that fold outward maximize usable space inside the cabin. Minimal frames maximize glass area, drawing natural light deeper into the sunroom and adjacent spaces. Paired with higher weather performance sills, the systems are built to withstand the region’s climate while allowing the sunroom to shift easily between a sheltered interior space and an open-air extension of the patio. Additionally, NanaWall aluminum clad systems feature clip-on cladding technology that allows the wood to breathe in environments where temperatures are extremely hot, humid, or cold. This, in turn, aligns with the renovation’s goal of resolving prior drainage and moisture issues. outdoor living with NanaWall aluminum clad systems Final Thoughts: Historic Cabin Design Reimagined for Modern Living Today, the Vandevert Homestead perfectly blends old-time charm with modern living. The renovation maintains the historic character of the original log structure while introducing brighter, more connected spaces that better engage with the surrounding landscape. With the transformation of the garage into a light-filled sunroom and flexible NanaWall aluminum clad folding doors, everyday living now flows naturally between the kitchen, dining area, sunroom, and patio. The result is a cabin that feels both timeless and renewed, where historic craftsmanship remains intact while the home experience is lighter, more open, and closely tied to the natural beauty of Central Oregon.

Wanting to change the layout of the kitchen and update the look to be more modern the clients entrusted Castle to come up with design ideas for their uniquely sized and uniquely shaped space. The kitchen was last remodeled to be customized to the last homeowners. The current homeowners almost never used a large space which had a built-in bench and desk. A new layout offers a wider opening between the Kitchen and Dining Room, shifts the direction which the peninsula faces. At the backdrop of the kitchen is a wide built-in buffet fit with a beverage fridge and open shelving that hosts plants, accessories and art.

Nestled in the lush landscape, a modern reinterpretation of a once-fallen barn now features a charming guest cottage with stylish details and contemporary amenities. Situated along a narrow lot in Germantown, New York, the cottage completes a cluster of existing buildings, forming an intimate courtyard on one side. Steel effect folding patio doors fully open the living areas to the expansive fields and the Catskill Mountains beyond. The homeowners, a young family with parents living abroad, envisioned a cozy yet modern ADU for extended stays. Designed by Lauren Cawse, AIA, architect and partner at The Art of Building, the year-round retreat draws inspiration from traditional local barns while embracing a seamless indoor-outdoor connection. Captivating Guest Cottage Design Enhances the Senses with Steel Effect Folding Patio Doors The modern ADU design started with the site itself. Positioned between residential and commercial neighbors, the elongated property required a careful balance of privacy and openness. Architect Lauren Cawse approached the layout by redefining the existing house and garage as the east and west sides of an outdoor room, with the new cottage forming its southern boundary. This arrangement created a clear courtyard near the main residence while directing the 800-square-foot guest house toward the open meadow and the distant Catskill Mountains. “The unique character of the site and its history inspired the architectural direction,” says Cawse. “The intent was to create a secondary structure in the compound in clear contrast to the modern farmhouse style of the house and garage.” A Barn-Inspired Exterior Adds Visual Flair The exterior envelope evokes a traditional barn with a simple gable shape, weathered wood siding, cedar shingles, and a foundation veneer made of local fieldstone. A large sliding barn door adds a complementary feature to the courtyard-facing side, creating a dynamic opening that maintains uninterrupted views through the cottage to the meadow beyond. Steel effect folding patio doors surrounding the structure add a modern touch of transparency, and simulated divided lites allow the contemporary glass wall systems to harmonize with the traditional elements of the modern ADU design. “The goal was to fully open the living areas to the outdoors, framing views to the meadows and mountains,” says Cawse. “The positioning of the NanaWall systems frames the views and, when open, dissolves the boundary between inside and out.” Interior Design That Mirrors Nature’s Tranquility Inside, the design program features a simple layout with one bedroom, a full bath, a kitchenette, and a living area with a wood-burning stove. The interior, a collaboration between The Art of Building and the homeowners, is defined by an understated palette and tactile materials that reflect the natural setting. Color is introduced through the framed glass views on all sides of the structure. Reclaimed timber collar ties span the ceiling overhead, while stone surfaces and naturally patinated metal accents add quiet texture throughout. Custom hand-painted Delft tiles along the kitchen backsplash add personal detail, and terra cotta flooring in the bathroom brings warmth and old-world charm. Soaring ceilings and abundant daylight create a peaceful play of light and shadow, shifting subtly with the seasons and emphasizing the cottage’s connection to the natural landscape outside. Sleek Steel Effect Folding Patio Doors Elevate the Modern ADU Design Aesthetic Three customized steel effect folding patio doors define the living space, each aligned to respond to a different edge of the site. The largest, spanning nearly 20 feet wide and just under eight feet tall, opens directly onto the stone patio, allowing the main gathering area to extend fully into the landscape. Along the side of the living room, a smaller 10-foot-wide system introduces more light and ventilation, nearly creating an open corner condition if not for the structural post that supports the façade and roofline. At the rear, a fourth ten-foot-wide system features a French door swing panel configuration that opens toward the courtyard, strengthening the design connection to the main residence. All steel effect folding patio doors were specified with a low-maintenance, water-rated Performance Sill to safeguard against inclement weather while providing a seamless, barrier-free transition to the outdoor patio. Unique Customizations for Visual Appeal and a Steel Effect Each folding patio door system is configured to open outward, maximizing usable floor space in the compact interior and allowing furniture placement to remain uninterrupted. By stacking outward, the steel effect folding patio doors, specified in a SE Classic Bronze powder coat, ensure every inch of the cottage is optimized. Simulated divided lites create a consistent rhythm across windows and doors, maintaining alignment with the traditional barn-inspired exterior. In the bedroom, a three-panel, 10-foot-wide system mirrors these customizations, matching the steel effect divided-lite pattern and outward-opening configuration, extending the indoor-outdoor connection while preserving visual continuity throughout the ADU. “The divided lites were crucial to the architectural vision, and while budget prohibited a steel and glass system, NanaWall Systems’ thin frames provide the open and airy feeling we hoped to attain,” says Cawse. “Simulated divided lites transition the thoroughly modern element of the glass walls to remain in harmony with the otherwise traditional palette.” Matching Windows and Doors: Create a Cohesive Design Program Alongside the larger openings in the living areas and bedroom, a smaller 3-foot-tall NanaWall tilt turn window was added to the bathroom. This window-sized NanaWall system perfectly matches the divided lite panels and sleek frames of the steel effect folding patio doors, creating a cohesive modern ADU design throughout. The compact opening provides ventilation and natural light, enhancing the spa-like atmosphere along with natural stone flooring. The matching glass lines and sleek profiles of the NanaWall Generation 4 comprehensive product line further unify visual consistency, allowing each system to fit into the architectural style seamlessly. “This project had three bifold glass walls, a pair of double French doors with sidelites, and a single tilt turn window,” says architect Lauren Cawse. “Being able to work with a single manufacturer provided aesthetic cohesiveness and simplified coordination.” Sustainability Where It Matters Most New York weather can vary from hot 85-degree summers to cold 26-degree winters. Creating an efficient living space was a primary goal. To achieve this, the design included Timber HP-insulated walls and floors with a heat pump system for effective heating and cooling. Additionally, the steel effect folding patio doors and windows were specified with double-glazed panels to ensure a tight building envelope. Indoor-Outdoor Living Spaces for Relaxing and Entertaining In-house landscape designer Liz Pulver worked closely with the team to conceive open-air spaces that enhanced the connection between inside and outside. To the south end of the lot, the landscape transitions into an “enhanced meadow,” allowing the cottage to feel embedded within the surrounding fields rather than set apart from them. A circular pool was designed to mimic a natural pond with a modest footprint. Around it, a minimalist fence and sunken stone ha-ha wall offer discreet safety for young children. Limited space due to existing infrastructure and zoning setbacks left only a small footprint for the swimming pool, prompting the designer to propose a circular form that maximized the usable swimming area. “We felt that the perfect way to integrate a pool into the property and to honor the landscape would be to treat the pool as a piece of art itself,” says Pulver. “The result is a beautiful round pool that serves as both a functional retreat and a sculptural moment.” Final Thoughts: A Barn-Inspired Design for Contemporary Living This modern ADU design skillfully combines modern features with the enduring charm of traditional barns. The outcome is a welcoming living space that stands out amid a stunning landscape. Natural materials that mimic the beauty of the outdoors, expansive steel effect folding patio doors that fill the space with fresh air and natural light, and a restrained interior design work together to create an inviting retreat for everyday living, throughout the seasons. “When entering the site, the cottage feels as though it was always there,” says Cawse. “It achieves its two opposing goals by creating a feeling of intimacy and enclosure near the house while also functioning as a threshold to the expansive fields and views beyond.” Explore how NanaWall folding patio doors elevate other ADU spaces in our inspiring project photo gallery!

Originally built in 1892, this quaint log cabin has undergone a transformative renovation while preserving its charming character. Located near the Little Deschutes River in Central Oregon, within the historic Vandert Homestead, the home now boasts bright, open spaces for everyday living, complete with flexible aluminum clad folding doors. Working alongside contractor Bales Inc., architect Jeff Klein from Klein Architecture led the renovation with the goal of opening the once dark interior to natural light and the surrounding landscape. Central to the design was transforming a deteriorating garage into a new functional sunroom, creating a light-filled space that reorients the cabin design toward the patio and natural environment. Restoring a Historic Cabin with Aluminum Clad Folding Doors outdoor living with aluminum clad folding door A Revamped Cabin Design for Indoor-Outdoor Living The former garage is now a transitional space between the cabin and a natural stone patio. Positioned along the south elevation, the sunroom captures daylight throughout the day while acting as a buffer between the interior and exterior environments. A revised roof assembly was developed to resolve previous drainage failures. Working with framers, the design team incorporated a sloping roof system with a waterproof membrane to direct water away from the structure. This approach not only protected the log walls but also created access to a rooftop deck from the upper level, adding functional outdoor space without expanding the building footprint. “It was also critical to transform the existing dark, segmented interior spaces by physically opening them up to the new sunroom,” says Klein. “NanaWall systems offered the ideal solution for what we were after.” historical homestead interior Improving Spatial Flow, From the Kitchen to the Sunroom The kitchen remained largely intact during the renovation, retaining many of the elements that had defined the cabin’s character for decades. Features such as the farmhouse sink, concrete countertops, butcher-block island, and built-in seating were retained, creating a perfect blend of old and new. What changed was how the kitchen connects to the surrounding rooms. The layout now flows naturally into an adjacent dining area before extending into the newly added sunroom, delivering a seamless transition from the interiors to the outdoors through aluminum clad folding doors. Historic log cabin with clad folding doors and windows A Light-Filled Sunroom Designed for Gatherings with Aluminum Clad Windows and Doors The newly added sunroom became the centerpiece of the cabin design. Designed as a bright, welcoming space, it connects the historic cabin to the natural stone patio beyond. Interior designer Sue Olson helped create the room's atmosphere by choosing finishes and furnishings that complement the cabin's rustic materials while keeping the space open and inviting. The sunroom captures sunlight throughout the day and serves as a flexible space for dining, relaxing, and entertaining. The addition was designed to sit comfortably alongside the existing log structure while introducing expansive glazing and aluminum clad folding doors that draw daylight deep into the home. NanaWall aluminum clad folding doors and windows Aluminum Clad Folding Doors Open the Sunroom to the Patio A NanaWall aluminum clad folding glass door opens the south wall of the sunroom, creating a direct connection to the natural stone patio. Spanning more than thirteen feet wide and nearly eight feet tall, the system allows the entire façade to open when the panels are folded back. Specified with pine wood frames and simulated divided lites, the door complements the cabin’s traditional materials while introducing the flexibility of modern indoor-outdoor living. When closed, the door frames the view while bringing daylight into the sunroom. When open, the space seamlessly flows into the patio. Plus, customized with double glazed panels, these aluminum clad systems offer an insulated barrier that keeps cold weather out and keeps comfortable interiors year-round. “The NanaWall system was the ideal solution for the proposed design,” says Klein. “The result is a seamless connection between the sheltered interior area and the openness of the outdoor environment.” aluminum clad folding windows A Folding Window Creates an Indoor-Outdoor Bar Complementing the folding door and indoor-outdoor cabin design, a NanaWall aluminum clad folding window was installed at bar height along the sunroom wall facing the patio. Stretching more than thirteen feet across and just over four feet in height, the opening transforms the wall into a casual indoor-outdoor serving counter. Specified with matching pine wood frames and simulated divided lites, the system folds away easily, creating an indoor-outdoor bar that encourages interaction between the sunroom and patio. When open, the counter becomes a flexible gathering point for meals, drinks, and conversation, allowing those inside and outside to share the space comfortably. “The NanaWall door and window systems played a pivotal role in achieving our design objectives,” says Klein. “The connection between the indoor and outdoor environment has become seamless.” inoor-outdoor living with clad folding windows and doors The Flexible Design Solution for Every Home Style Beyond creating large openings, the NanaWall aluminum clad folding doors were chosen for how well they integrate with the cabin’s traditional architecture while delivering modern functionality.

Nestled in the lush landscape, a modern reinterpretation of a once-fallen barn now features a charming guest cottage with stylish details and contemporary amenities. Situated along a narrow lot in Germantown, New York, the cottage completes a cluster of existing buildings, forming an intimate courtyard on one side. Steel effect folding patio doors fully open the living areas to the expansive fields and the Catskill Mountains beyond. The homeowners, a young family with parents living abroad, envisioned a cozy yet modern ADU for extended stays. Designed by Lauren Cawse, AIA, architect and partner at The Art of Building, the year-round retreat draws inspiration from traditional local barns while embracing a seamless indoor-outdoor connection. Captivating Guest Cottage Design Enhances the Senses with Steel Effect Folding Patio Doors The modern ADU design started with the site itself. Positioned between residential and commercial neighbors, the elongated property required a careful balance of privacy and openness. Architect Lauren Cawse approached the layout by redefining the existing house and garage as the east and west sides of an outdoor room, with the new cottage forming its southern boundary. This arrangement created a clear courtyard near the main residence while directing the 800-square-foot guest house toward the open meadow and the distant Catskill Mountains. “The unique character of the site and its history inspired the architectural direction,” says Cawse. “The intent was to create a secondary structure in the compound in clear contrast to the modern farmhouse style of the house and garage.” A Barn-Inspired Exterior Adds Visual Flair The exterior envelope evokes a traditional barn with a simple gable shape, weathered wood siding, cedar shingles, and a foundation veneer made of local fieldstone. A large sliding barn door adds a complementary feature to the courtyard-facing side, creating a dynamic opening that maintains uninterrupted views through the cottage to the meadow beyond. Steel effect folding patio doors surrounding the structure add a modern touch of transparency, and simulated divided lites allow the contemporary glass wall systems to harmonize with the traditional elements of the modern ADU design. “The goal was to fully open the living areas to the outdoors, framing views to the meadows and mountains,” says Cawse. “The positioning of the NanaWall systems frames the views and, when open, dissolves the boundary between inside and out.” Interior Design That Mirrors Nature’s Tranquility Inside, the design program features a simple layout with one bedroom, a full bath, a kitchenette, and a living area with a wood-burning stove. The interior, a collaboration between The Art of Building and the homeowners, is defined by an understated palette and tactile materials that reflect the natural setting. Color is introduced through the framed glass views on all sides of the structure. Reclaimed timber collar ties span the ceiling overhead, while stone surfaces and naturally patinated metal accents add quiet texture throughout. Custom hand-painted Delft tiles along the kitchen backsplash add personal detail, and terra cotta flooring in the bathroom brings warmth and old-world charm. Soaring ceilings and abundant daylight create a peaceful play of light and shadow, shifting subtly with the seasons and emphasizing the cottage’s connection to the natural landscape outside. Sleek Steel Effect Folding Patio Doors Elevate the Modern ADU Design Aesthetic Three customized steel effect folding patio doors define the living space, each aligned to respond to a different edge of the site. The largest, spanning nearly 20 feet wide and just under eight feet tall, opens directly onto the stone patio, allowing the main gathering area to extend fully into the landscape. Along the side of the living room, a smaller 10-foot-wide system introduces more light and ventilation, nearly creating an open corner condition if not for the structural post that supports the façade and roofline. At the rear, a fourth ten-foot-wide system features a French door swing panel configuration that opens toward the courtyard, strengthening the design connection to the main residence. All steel effect folding patio doors were specified with a low-maintenance, water-rated Performance Sill to safeguard against inclement weather while providing a seamless, barrier-free transition to the outdoor patio. Unique Customizations for Visual Appeal and a Steel Effect Each folding patio door system is configured to open outward, maximizing usable floor space in the compact interior and allowing furniture placement to remain uninterrupted. By stacking outward, the steel effect folding patio doors, specified in a SE Classic Bronze powder coat, ensure every inch of the cottage is optimized. Simulated divided lites create a consistent rhythm across windows and doors, maintaining alignment with the traditional barn-inspired exterior. In the bedroom, a three-panel, 10-foot-wide system mirrors these customizations, matching the steel effect divided-lite pattern and outward-opening configuration, extending the indoor-outdoor connection while preserving visual continuity throughout the ADU. “The divided lites were crucial to the architectural vision, and while budget prohibited a steel and glass system, NanaWall Systems’ thin frames provide the open and airy feeling we hoped to attain,” says Cawse. “Simulated divided lites transition the thoroughly modern element of the glass walls to remain in harmony with the otherwise traditional palette.” Matching Windows and Doors: Create a Cohesive Design Program Alongside the larger openings in the living areas and bedroom, a smaller 3-foot-tall NanaWall tilt turn window was added to the bathroom. This window-sized NanaWall system perfectly matches the divided lite panels and sleek frames of the steel effect folding patio doors, creating a cohesive modern ADU design throughout. The compact opening provides ventilation and natural light, enhancing the spa-like atmosphere along with natural stone flooring. The matching glass lines and sleek profiles of the NanaWall Generation 4 comprehensive product line further unify visual consistency, allowing each system to fit into the architectural style seamlessly. “This project had three bifold glass walls, a pair of double French doors with sidelites, and a single tilt turn window,” says architect Lauren Cawse. “Being able to work with a single manufacturer provided aesthetic cohesiveness and simplified coordination.” Sustainability Where It Matters Most New York weather can vary from hot 85-degree summers to cold 26-degree winters. Creating an efficient living space was a primary goal. To achieve this, the design included Timber HP-insulated walls and floors with a heat pump system for effective heating and cooling. Additionally, the steel effect folding patio doors and windows were specified with double-glazed panels to ensure a tight building envelope. Indoor-Outdoor Living Spaces for Relaxing and Entertaining In-house landscape designer Liz Pulver worked closely with the team to conceive open-air spaces that enhanced the connection between inside and outside. To the south end of the lot, the landscape transitions into an “enhanced meadow,” allowing the cottage to feel embedded within the surrounding fields rather than set apart from them. A circular pool was designed to mimic a natural pond with a modest footprint. Around it, a minimalist fence and sunken stone ha-ha wall offer discreet safety for young children. Limited space due to existing infrastructure and zoning setbacks left only a small footprint for the swimming pool, prompting the designer to propose a circular form that maximized the usable swimming area. “We felt that the perfect way to integrate a pool into the property and to honor the landscape would be to treat the pool as a piece of art itself,” says Pulver. “The result is a beautiful round pool that serves as both a functional retreat and a sculptural moment.” Final Thoughts: A Barn-Inspired Design for Contemporary Living This modern ADU design skillfully combines modern features with the enduring charm of traditional barns. The outcome is a welcoming living space that stands out amid a stunning landscape. Natural materials that mimic the beauty of the outdoors, expansive steel effect folding patio doors that fill the space with fresh air and natural light, and a restrained interior design work together to create an inviting retreat for everyday living, throughout the seasons. “When entering the site, the cottage feels as though it was always there,” says Cawse. “It achieves its two opposing goals by creating a feeling of intimacy and enclosure near the house while also functioning as a threshold to the expansive fields and views beyond.” Explore how NanaWall folding patio doors elevate other ADU spaces in our inspiring project photo gallery!

Set on a narrow hillside lot overlooking the San Francisco Bay in Point Richmond, California, Bay Heirloom is a Mid-Century Modern family home restored, modernized and adapted for contemporary living. Oriented south-southwest toward the Marin Headlands, with views of the Golden Gate Bridge, the residence captures shifting Bay light throughout the day, from fog-muted mornings to vivid, glowing sunsets. The home was built by Karlyn Neel’s grandfather, the owner of the construction company Flo-Crete, one of the Bay Area’s early concrete pumping firms. Flo-Crete completed the foundation and structural concrete work, with family photographs documenting the original cinderblock walls and pours. The firm also contributed to major regional infrastructure projects, including the Transbay BART tube and Candlestick Park, situating the house within a broader legacy of Bay Area construction. Growing up, Neel spent considerable time in the home, developing an early appreciation for mid-century modern principles. Instead of parting with this family heirloom, she purchased the home from her grandfather’s estate. While her grandfather continued to live in the Point Richmond house, Neel purchased a Mid-Century Modern residence in Palm Desert. In contrast to the Bay Area’s cool temperatures, salt air, and persistent winds, the desert home is shaped by heat and sun and requires a different material response. A substantial renovation she led there emphasized thermal performance, filtered light, and restrained detailing. The experience later informed the restoration of her Bay Area family home. What began as a modest Mid-Century Modern update expanded when decades of exposure to marine conditions revealed leaks and significant structural and seismic deficiencies. Neel was determined to honor her grandfather’s perseverance and without hesitation pivoted to a much more intensive project. Addressing these challenges required close coordination between Neel, Klopf Architecture and Kasten Builders, with architectural restraint and construction precision guiding each intervention. Rather than alter the home’s defining features, the project focused on reinforcing the structure from within. Discreet beams were embedded along the rear facade and in an upstairs wall, strengthening the building while maximizing the wall of glass facing the Bay and opening the wall between the kitchen and the living space. These structural interventions allowed the space to open fully to the Bay without visual interruption, with the kitchen repositioned as the social and functional core of an open, continuous living space. The building envelope was updated using weather- and corrosion-resistant materials appropriate to the marine environment. The house unfolds vertically from the street, beginning with a modest garage level and workshop, with the main living spaces located below. Original slate flooring at the entry was preserved, along with select furnishings and artwork collected by Neel’s grandfather, anchoring the restored interior in its past. A restrained palette of black accents and pale, natural finishes replaces darker wood tones, reinforcing openness and calm. A naturally illuminated stair connects to the lowest level, where a former basement was transformed into a guest suite and family room opening onto a deck. From there, steps lead directly to a small concrete boat ramp at the water’s edge. Throughout the project, decisions were guided by continuity rather than transformation for its own sake. Lessons drawn from both desert and coastal climates informed a material strategy rooted in performance and restraint. Bay Heirloom stands as a measured evolution of a family house, structurally renewed and carefully modernized, grounded in the discipline and care that first shaped it.

Working with framers, the design team incorporated a sloping roof system with a waterproof membrane to direct water away from the structure. This approach not only protected the log walls but also created access to a rooftop deck from the upper level, adding functional outdoor space without expanding the building footprint. “It was also critical to transform the existing dark, segmented interior spaces by physically opening them up to the new sunroom,” says Klein. “NanaWall systems offered the ideal solution for what we were after.” historical homestead interior Improving Spatial Flow, From the Kitchen to the Sunroom The kitchen remained largely intact during the renovation, retaining many of the elements that had defined the cabin’s character for decades. Features such as the farmhouse sink, concrete countertops, butcher-block island, and built-in seating were retained, creating a perfect blend of old and new. What changed was how the kitchen connects to the surrounding rooms. The layout now flows naturally into an adjacent dining area before extending into the newly added sunroom, delivering a seamless transition from the interiors to the outdoors through aluminum clad folding doors. Historic log cabin with clad folding doors and windows A Light-Filled Sunroom Designed for Gatherings with Aluminum Clad Windows and Doors The newly added sunroom became the centerpiece of the cabin design. Designed as a bright, welcoming space, it connects the historic cabin to the natural stone patio beyond. Interior designer Sue Olson helped create the room's atmosphere by choosing finishes and furnishings that complement the cabin's rustic materials while keeping the space open and inviting. The sunroom captures sunlight throughout the day and serves as a flexible space for dining, relaxing, and entertaining. The addition was designed to sit comfortably alongside the existing log structure while introducing expansive glazing and aluminum clad folding doors that draw daylight deep into the home. NanaWall aluminum clad folding doors and windows Aluminum Clad Folding Doors Open the Sunroom to the Patio A NanaWall aluminum clad folding glass door opens the south wall of the sunroom, creating a direct connection to the natural stone patio. Spanning more than thirteen feet wide and nearly eight feet tall, the system allows the entire façade to open when the panels are folded back. Specified with pine wood frames and simulated divided lites, the door complements the cabin’s traditional materials while introducing the flexibility of modern indoor-outdoor living. When closed, the door frames the view while bringing daylight into the sunroom. When open, the space seamlessly flows into the patio. Plus, customized with double glazed panels, these aluminum clad systems offer an insulated barrier that keeps cold weather out and keeps comfortable interiors year-round. “The NanaWall system was the ideal solution for the proposed design,” says Klein. “The result is a seamless connection between the sheltered interior area and the openness of the outdoor environment.” aluminum clad folding windows A Folding Window Creates an Indoor-Outdoor Bar Complementing the folding door and indoor-outdoor cabin design, a NanaWall aluminum clad folding window was installed at bar height along the sunroom wall facing the patio. Stretching more than thirteen feet across and just over four feet in height, the opening transforms the wall into a casual indoor-outdoor serving counter. Specified with matching pine wood frames and simulated divided lites, the system folds away easily, creating an indoor-outdoor bar that encourages interaction between the sunroom and patio. When open, the counter becomes a flexible gathering point for meals, drinks, and conversation, allowing those inside and outside to share the space comfortably. “The NanaWall door and window systems played a pivotal role in achieving our design objectives,” says Klein. “The connection between the indoor and outdoor environment has become seamless.” inoor-outdoor living with clad folding windows and doors The Flexible Design Solution for Every Home Style Beyond creating large openings, the NanaWall aluminum clad folding doors were chosen for how well they integrate with the cabin’s traditional architecture while delivering modern functionality. The wood clad panels, specified with simulated divided lites, reflect the style and charm of classic window detailing, while panels that fold outward maximize usable space inside the cabin. Minimal frames maximize glass area, drawing natural light deeper into the sunroom and adjacent spaces. Paired with higher weather performance sills, the systems are built to withstand the region’s climate while allowing the sunroom to shift easily between a sheltered interior space and an open-air extension of the patio. Additionally, NanaWall aluminum clad systems feature clip-on cladding technology that allows the wood to breathe in environments where temperatures are extremely hot, humid, or cold. This, in turn, aligns with the renovation’s goal of resolving prior drainage and moisture issues. outdoor living with NanaWall aluminum clad systems Final Thoughts: Historic Cabin Design Reimagined for Modern Living Today, the Vandevert Homestead perfectly blends old-time charm with modern living. The renovation maintains the historic character of the original log structure while introducing brighter, more connected spaces that better engage with the surrounding landscape. With the transformation of the garage into a light-filled sunroom and flexible NanaWall aluminum clad folding doors, everyday living now flows naturally between the kitchen, dining area, sunroom, and patio. The result is a cabin that feels both timeless and renewed, where historic craftsmanship remains intact while the home experience is lighter, more open, and closely tied to the natural beauty of Central Oregon.

Nestled in the lush landscape, a modern reinterpretation of a once-fallen barn now features a charming guest cottage with stylish details and contemporary amenities. Situated along a narrow lot in Germantown, New York, the cottage completes a cluster of existing buildings, forming an intimate courtyard on one side. Steel effect folding patio doors fully open the living areas to the expansive fields and the Catskill Mountains beyond. The homeowners, a young family with parents living abroad, envisioned a cozy yet modern ADU for extended stays. Designed by Lauren Cawse, AIA, architect and partner at The Art of Building, the year-round retreat draws inspiration from traditional local barns while embracing a seamless indoor-outdoor connection. Captivating Guest Cottage Design Enhances the Senses with Steel Effect Folding Patio Doors The modern ADU design started with the site itself. Positioned between residential and commercial neighbors, the elongated property required a careful balance of privacy and openness. Architect Lauren Cawse approached the layout by redefining the existing house and garage as the east and west sides of an outdoor room, with the new cottage forming its southern boundary. This arrangement created a clear courtyard near the main residence while directing the 800-square-foot guest house toward the open meadow and the distant Catskill Mountains. “The unique character of the site and its history inspired the architectural direction,” says Cawse. “The intent was to create a secondary structure in the compound in clear contrast to the modern farmhouse style of the house and garage.” A Barn-Inspired Exterior Adds Visual Flair The exterior envelope evokes a traditional barn with a simple gable shape, weathered wood siding, cedar shingles, and a foundation veneer made of local fieldstone. A large sliding barn door adds a complementary feature to the courtyard-facing side, creating a dynamic opening that maintains uninterrupted views through the cottage to the meadow beyond. Steel effect folding patio doors surrounding the structure add a modern touch of transparency, and simulated divided lites allow the contemporary glass wall systems to harmonize with the traditional elements of the modern ADU design. “The goal was to fully open the living areas to the outdoors, framing views to the meadows and mountains,” says Cawse. “The positioning of the NanaWall systems frames the views and, when open, dissolves the boundary between inside and out.” Interior Design That Mirrors Nature’s Tranquility Inside, the design program features a simple layout with one bedroom, a full bath, a kitchenette, and a living area with a wood-burning stove. The interior, a collaboration between The Art of Building and the homeowners, is defined by an understated palette and tactile materials that reflect the natural setting. Color is introduced through the framed glass views on all sides of the structure. Reclaimed timber collar ties span the ceiling overhead, while stone surfaces and naturally patinated metal accents add quiet texture throughout. Custom hand-painted Delft tiles along the kitchen backsplash add personal detail, and terra cotta flooring in the bathroom brings warmth and old-world charm. Soaring ceilings and abundant daylight create a peaceful play of light and shadow, shifting subtly with the seasons and emphasizing the cottage’s connection to the natural landscape outside. Sleek Steel Effect Folding Patio Doors Elevate the Modern ADU Design Aesthetic Three customized steel effect folding patio doors define the living space, each aligned to respond to a different edge of the site. The largest, spanning nearly 20 feet wide and just under eight feet tall, opens directly onto the stone patio, allowing the main gathering area to extend fully into the landscape. Along the side of the living room, a smaller 10-foot-wide system introduces more light and ventilation, nearly creating an open corner condition if not for the structural post that supports the façade and roofline. At the rear, a fourth ten-foot-wide system features a French door swing panel configuration that opens toward the courtyard, strengthening the design connection to the main residence. All steel effect folding patio doors were specified with a low-maintenance, water-rated Performance Sill to safeguard against inclement weather while providing a seamless, barrier-free transition to the outdoor patio. Unique Customizations for Visual Appeal and a Steel Effect Each folding patio door system is configured to open outward, maximizing usable floor space in the compact interior and allowing furniture placement to remain uninterrupted. By stacking outward, the steel effect folding patio doors, specified in a SE Classic Bronze powder coat, ensure every inch of the cottage is optimized. Simulated divided lites create a consistent rhythm across windows and doors, maintaining alignment with the traditional barn-inspired exterior. In the bedroom, a three-panel, 10-foot-wide system mirrors these customizations, matching the steel effect divided-lite pattern and outward-opening configuration, extending the indoor-outdoor connection while preserving visual continuity throughout the ADU. “The divided lites were crucial to the architectural vision, and while budget prohibited a steel and glass system, NanaWall Systems’ thin frames provide the open and airy feeling we hoped to attain,” says Cawse. “Simulated divided lites transition the thoroughly modern element of the glass walls to remain in harmony with the otherwise traditional palette.” Matching Windows and Doors: Create a Cohesive Design Program Alongside the larger openings in the living areas and bedroom, a smaller 3-foot-tall NanaWall tilt turn window was added to the bathroom. This window-sized NanaWall system perfectly matches the divided lite panels and sleek frames of the steel effect folding patio doors, creating a cohesive modern ADU design throughout. The compact opening provides ventilation and natural light, enhancing the spa-like atmosphere along with natural stone flooring. The matching glass lines and sleek profiles of the NanaWall Generation 4 comprehensive product line further unify visual consistency, allowing each system to fit into the architectural style seamlessly. “This project had three bifold glass walls, a pair of double French doors with sidelites, and a single tilt turn window,” says architect Lauren Cawse. “Being able to work with a single manufacturer provided aesthetic cohesiveness and simplified coordination.” Sustainability Where It Matters Most New York weather can vary from hot 85-degree summers to cold 26-degree winters. Creating an efficient living space was a primary goal. To achieve this, the design included Timber HP-insulated walls and floors with a heat pump system for effective heating and cooling. Additionally, the steel effect folding patio doors and windows were specified with double-glazed panels to ensure a tight building envelope. Indoor-Outdoor Living Spaces for Relaxing and Entertaining In-house landscape designer Liz Pulver worked closely with the team to conceive open-air spaces that enhanced the connection between inside and outside. To the south end of the lot, the landscape transitions into an “enhanced meadow,” allowing the cottage to feel embedded within the surrounding fields rather than set apart from them. A circular pool was designed to mimic a natural pond with a modest footprint. Around it, a minimalist fence and sunken stone ha-ha wall offer discreet safety for young children. Limited space due to existing infrastructure and zoning setbacks left only a small footprint for the swimming pool, prompting the designer to propose a circular form that maximized the usable swimming area. “We felt that the perfect way to integrate a pool into the property and to honor the landscape would be to treat the pool as a piece of art itself,” says Pulver. “The result is a beautiful round pool that serves as both a functional retreat and a sculptural moment.” Final Thoughts: A Barn-Inspired Design for Contemporary Living This modern ADU design skillfully combines modern features with the enduring charm of traditional barns. The outcome is a welcoming living space that stands out amid a stunning landscape. Natural materials that mimic the beauty of the outdoors, expansive steel effect folding patio doors that fill the space with fresh air and natural light, and a restrained interior design work together to create an inviting retreat for everyday living, throughout the seasons. “When entering the site, the cottage feels as though it was always there,” says Cawse. “It achieves its two opposing goals by creating a feeling of intimacy and enclosure near the house while also functioning as a threshold to the expansive fields and views beyond.” Explore how NanaWall folding patio doors elevate other ADU spaces in our inspiring project photo gallery!

Originally built in 1892, this quaint log cabin has undergone a transformative renovation while preserving its charming character. Located near the Little Deschutes River in Central Oregon, within the historic Vandert Homestead, the home now boasts bright, open spaces for everyday living, complete with flexible aluminum clad folding doors. Working alongside contractor Bales Inc., architect Jeff Klein from Klein Architecture led the renovation with the goal of opening the once dark interior to natural light and the surrounding landscape. Central to the design was transforming a deteriorating garage into a new functional sunroom, creating a light-filled space that reorients the cabin design toward the patio and natural environment.

The homeowners, a young family with parents living abroad, envisioned a cozy yet modern ADU for extended stays. Designed by Lauren Cawse, AIA, architect and partner at The Art of Building, the year-round retreat draws inspiration from traditional local barns while embracing a seamless indoor-outdoor connection. Captivating Guest Cottage Design Enhances the Senses with Steel Effect Folding Patio Doors The modern ADU design started with the site itself. Positioned between residential and commercial neighbors, the elongated property required a careful balance of privacy and openness. Architect Lauren Cawse approached the layout by redefining the existing house and garage as the east and west sides of an outdoor room, with the new cottage forming its southern boundary. This arrangement created a clear courtyard near the main residence while directing the 800-square-foot guest house toward the open meadow and the distant Catskill Mountains. “The unique character of the site and its history inspired the architectural direction,” says Cawse. “The intent was to create a secondary structure in the compound in clear contrast to the modern farmhouse style of the house and garage.” A Barn-Inspired Exterior Adds Visual Flair The exterior envelope evokes a traditional barn with a simple gable shape, weathered wood siding, cedar shingles, and a foundation veneer made of local fieldstone. A large sliding barn door adds a complementary feature to the courtyard-facing side, creating a dynamic opening that maintains uninterrupted views through the cottage to the meadow beyond. Steel effect folding patio doors surrounding the structure add a modern touch of transparency, and simulated divided lites allow the contemporary glass wall systems to harmonize with the traditional elements of the modern ADU design. “The goal was to fully open the living areas to the outdoors, framing views to the meadows and mountains,” says Cawse. “The positioning of the NanaWall systems frames the views and, when open, dissolves the boundary between inside and out.” Interior Design That Mirrors Nature’s Tranquility Inside, the design program features a simple layout with one bedroom, a full bath, a kitchenette, and a living area with a wood-burning stove. The interior, a collaboration between The Art of Building and the homeowners, is defined by an understated palette and tactile materials that reflect the natural setting. Color is introduced through the framed glass views on all sides of the structure. Reclaimed timber collar ties span the ceiling overhead, while stone surfaces and naturally patinated metal accents add quiet texture throughout. Custom hand-painted Delft tiles along the kitchen backsplash add personal detail, and terra cotta flooring in the bathroom brings warmth and old-world charm. Soaring ceilings and abundant daylight create a peaceful play of light and shadow, shifting subtly with the seasons and emphasizing the cottage’s connection to the natural landscape outside. Sleek Steel Effect Folding Patio Doors Elevate the Modern ADU Design Aesthetic Three customized steel effect folding patio doors define the living space, each aligned to respond to a different edge of the site. The largest, spanning nearly 20 feet wide and just under eight feet tall, opens directly onto the stone patio, allowing the main gathering area to extend fully into the landscape. Along the side of the living room, a smaller 10-foot-wide system introduces more light and ventilation, nearly creating an open corner condition if not for the structural post that supports the façade and roofline. At the rear, a fourth ten-foot-wide system features a French door swing panel configuration that opens toward the courtyard, strengthening the design connection to the main residence. All steel effect folding patio doors were specified with a low-maintenance, water-rated Performance Sill to safeguard against inclement weather while providing a seamless, barrier-free transition to the outdoor patio. Unique Customizations for Visual Appeal and a Steel Effect Each folding patio door system is configured to open outward, maximizing usable floor space in the compact interior and allowing furniture placement to remain uninterrupted. By stacking outward, the steel effect folding patio doors, specified in a SE Classic Bronze powder coat, ensure every inch of the cottage is optimized. Simulated divided lites create a consistent rhythm across windows and doors, maintaining alignment with the traditional barn-inspired exterior. In the bedroom, a three-panel, 10-foot-wide system mirrors these customizations, matching the steel effect divided-lite pattern and outward-opening configuration, extending the indoor-outdoor connection while preserving visual continuity throughout the ADU. “The divided lites were crucial to the architectural vision, and while budget prohibited a steel and glass system, NanaWall Systems’ thin frames provide the open and airy feeling we hoped to attain,” says Cawse. “Simulated divided lites transition the thoroughly modern element of the glass walls to remain in harmony with the otherwise traditional palette.” Matching Windows and Doors: Create a Cohesive Design Program Alongside the larger openings in the living areas and bedroom, a smaller 3-foot-tall NanaWall tilt turn window was added to the bathroom. This window-sized NanaWall system perfectly matches the divided lite panels and sleek frames of the steel effect folding patio doors, creating a cohesive modern ADU design throughout. The compact opening provides ventilation and natural light, enhancing the spa-like atmosphere along with natural stone flooring. The matching glass lines and sleek profiles of the NanaWall Generation 4 comprehensive product line further unify visual consistency, allowing each system to fit into the architectural style seamlessly. “This project had three bifold glass walls, a pair of double French doors with sidelites, and a single tilt turn window,” says architect Lauren Cawse. “Being able to work with a single manufacturer provided aesthetic cohesiveness and simplified coordination.” Sustainability Where It Matters Most New York weather can vary from hot 85-degree summers to cold 26-degree winters. Creating an efficient living space was a primary goal. To achieve this, the design included Timber HP-insulated walls and floors with a heat pump system for effective heating and cooling. Additionally, the steel effect folding patio doors and windows were specified with double-glazed panels to ensure a tight building envelope. Indoor-Outdoor Living Spaces for Relaxing and Entertaining In-house landscape designer Liz Pulver worked closely with the team to conceive open-air spaces that enhanced the connection between inside and outside. To the south end of the lot, the landscape transitions into an “enhanced meadow,” allowing the cottage to feel embedded within the surrounding fields rather than set apart from them. A circular pool was designed to mimic a natural pond with a modest footprint. Around it, a minimalist fence and sunken stone ha-ha wall offer discreet safety for young children. Limited space due to existing infrastructure and zoning setbacks left only a small footprint for the swimming pool, prompting the designer to propose a circular form that maximized the usable swimming area. “We felt that the perfect way to integrate a pool into the property and to honor the landscape would be to treat the pool as a piece of art itself,” says Pulver. “The result is a beautiful round pool that serves as both a functional retreat and a sculptural moment.” Final Thoughts: A Barn-Inspired Design for Contemporary Living This modern ADU design skillfully combines modern features with the enduring charm of traditional barns. The outcome is a welcoming living space that stands out amid a stunning landscape. Natural materials that mimic the beauty of the outdoors, expansive steel effect folding patio doors that fill the space with fresh air and natural light, and a restrained interior design work together to create an inviting retreat for everyday living, throughout the seasons. “When entering the site, the cottage feels as though it was always there,” says Cawse. “It achieves its two opposing goals by creating a feeling of intimacy and enclosure near the house while also functioning as a threshold to the expansive fields and views beyond.” Explore how NanaWall folding patio doors elevate other ADU spaces in our inspiring project photo gallery!
