The Harmonious Blending of Inside to Out with Wood Framed Patio Doors
By NanaWall Systems, September 3, 2025
Wood framed patio doors
Some homes are designed to impress from the outside. This one was reimagined to breathe from the inside out with wood framed patio doors. For a family of music lovers and outdoor enthusiasts, the goal was about connection. Connection to each other, to the seasons, to nature, to sound, and to their lush backyard space for daily life and family gatherings.
Designed by Jason Hanrahan of Mode Architects, the home features a thoughtfully placed NanaWall kitchen pass-through window and, later, wide bifold doors in the family sunroom. The design evolved in two phases to fit the family’s indoor-outdoor lifestyle perfectly. The result is a renovation defined by openness, light, and laid-back living.
A Home Shaped by Light, Music, Wood Framed Patio Doors, and a Pass-Through Window
Kitchen Renovation Opens Space to Light and Entertaining with a Pass-Through Window
During phase one of the renovation, the existing kitchen was reimagined to replace a restrictive floor plan and outdated appliances. Central to its new design is a three-panel NanaWall SL60 folding window system—sized at counter height to serve as a flexible pass-through window for alfresco dining and entertaining. Custom divided lites were added to complement the home’s existing window styles.
The window frames were finished in a warm, off-white on both interior and exterior, tying the kitchen seamlessly to the rest of the home and its façade. The result is a transitional space that connects the kitchen directly to the outdoor dining area, a seamless connection across spaces.
“The countertop-height NanaWall system made the kitchen fit better into the family’s lifestyle,” says Hanrahan. “It supports hosting and day-to-day use without turning the kitchen into a full opening.”
Designed for Living: Home Reimagined Around How the Family Connects
After phase one introduced a NanaWall pass-through window in the kitchen, making serving, conversation, and time outside effortless, the homeowners returned to MODE to reimagine their older sunroom. The goal: a living room and music lounge that could open completely to the backyard. The solution was incorporating a full-height, five-panel NW Clad 740 wood framed patio doors. The Generation 4 folding glass wall offered the slimmest aluminum clad frames available, and therefore, was the ideal solution to achieve seamless connectivity.
Outside, the frames were finished in a warm off-white to match the façade. Inside, solid wood frames seamlessly integrate with the mushroom wood paneling and millwork. The nearly 15-foot-wide system was customized with divided lites placed high up to add rhythm while preserving unobstructed views and keeping transitions seamless.
“We wanted to maximize the opening size,” says Jason. “Not just to maximize light, but literally the opening as well. The family sunroom space became more useful.”
A Living Sunroom That Folds Open to the Garden
MODE centered the second half of the home renovation on the family sunroom, featuring wood framed patio doors to create a seamless transition from the interior to the garden. It’s the difference between “a room with a view” and a room that becomes the view. With the nearly 8-foot-tall system open, music spills outside; with it closed, daylight, acoustics, and comfort remain finely tuned.
“You are sitting in the house with the family. The opening frames the view of the pond and the trees,” describes Architect Jason Hanrahan. “They liked how it connected them with their family when they were outside… it made it more cohesive.”
Choosing Materials that Reflect Nature and Serenity
According to the architect, the design aims to bring the outdoors in with an organic material approach. Inside, the room is wrapped in mushroom wood reclaimed boards, whose textured grain warms the acoustics and steadies the eye. Large-format tiles keep lines calm and maintenance easy.
Outside, a long concrete tread and natural stone hold the grade without hard edges. Nothing shouts; everything contributes to a single idea: bring the outdoors in and the indoors out.
Energy Efficiency Meets Everyday Living
The systems’ energy-efficient and performance engineering make the sunroom a four-season retreat. The architect chose NanaWall wood framed patio doors to maximize the existing exterior opening, provide intuitive and easy daily operation, and create a threshold that feels like part of the floor rather than a barrier. T hese are hallmarks of NanaWall wood framed patio doors: engineered for durability and frequent use, precision-gliding panels, and performance-tested.
To ensure year-round comfort, the NanaWall wood framed patio doors and pass-through window were specified with double glazed panels for optimal performance regardless of weather. Paired with the thermally broken Low Profile Saddle Sill, the bifold door not only offers energy efficiency but also a seamless, barefoot-friendly threshold to the outdoors.
Final Thoughts
From weeknight dinners to weekend music sessions, this is now a home that meets the family at the place they actually live, gather, and connect in. The kitchen pass-through window keeps everyday hosting effortless. The music room turns into a garden room in seconds, inviting breezes and conversation across one continuous plane.
Here, NanaWall wood framed patio doors added versatile usable square footage and extended the soul of the home outdoors. By focusing on how the family truly lives, this home now opens in all the right ways: to light, to laughter, to nature, and to each other.

The Yin-Yang House is a net-zero energy single-family home in a quiet Venice, CA neighborhood. The design objective was to create a space for a large and growing family with several children, which would create a calm, relaxed and organized environment that emphasizes public family space. The home also serves as a place to entertain, and a welcoming space for teenagers as they seek social space with friends.
The home is organized around a series of courtyards and other outdoor spaces that integrate with the interior of the house. Facing the street the house appears to be solid. However, behind the steel entry door is a courtyard, which reveals the indoor-outdoor nature of the house behind the solid exterior. From the entry courtyard, the entire space to the rear garden wall can be seen; the first clue of the home’s spatial connection between inside and out. These spaces are designed for entertainment, and the 40 foot sliding glass door to the living room enhances the harmonic relationship of the main room, allowing the owners to host many guests without the feeling of being overburdened.
The tensions of the house’s exterior are subtly underscored by a 12-inch steel band that hews close to, but sometimes rises above or falls below the floor line of the second floor – a continuous loop moving inside and out like a pen that is never lifted from the page, but reinforces the intent to spatially weave together the indoors with the outside as a single space.
Scale manipulation also plays a formal role in the design of the structure. From the rear, the house appears to be a single-story volume. The large master bedroom window and the outdoor steps are scaled to support this illusion. It is only when the steps are animated with people that one realizes the true scale of the house is two stories.
The kitchen is the heart of the house, with an open working area that allows the owner, an accomplished chef, to converse with friends while cooking. Bedrooms are intentionally designed to be very small and simple; allowing for larger public spaces, emphasizing the family over individual domains. The breakfast room looks across an outdoor courtyard to the guest room/kids playroom, establishing a visual connection while defining the separation of uses. The children can play outdoors while under adult supervision from the dining area or the office, or do homework in the office while adults occupy the adjacent outdoor or indoor space.
Many of the materials used, including the bamboo interior, composite stone and tile countertops and bathroom finishes are recycled, and reinforce the environmental DNA of the house, which also has a green roof. Blown-in cellulose insulation, radiant heating and a host of other sustainable features aids in the performance of the building’s heating and cooling.
The active systems in the home include a 12 KW solar photovoltaic panel system, the largest such residential system available on the market. The solar panels also provide shade from the sun, preventing the house from becoming overheated. The owners have been in the home for over nine months and have yet to receive a power bill.

Lincoln Farmhouse
LEED-H Platinum, Net-Positive Energy
OVERVIEW. This LEED Platinum certified modern farmhouse ties into the cultural landscape of Lincoln, Massachusetts - a town known for its rich history, farming traditions, conservation efforts, and visionary architecture. The goal was to design and build a new single family home on 1.8 acres that respects the neighborhood’s agrarian roots, produces more energy than it consumes, and provides the family with flexible spaces to live-play-work-entertain. The resulting 2,800 SF home is proof that families do not need to compromise on style, space or comfort in a highly energy-efficient and healthy home.
CONNECTION TO NATURE. The attached garage is ubiquitous in new construction in New England’s cold climate. This home’s barn-inspired garage is intentionally detached from the main dwelling. A covered walkway connects the two structures, creating an intentional connection with the outdoors between auto and home.
FUNCTIONAL FLEXIBILITY. With a modest footprint, each space must serve a specific use, but also be flexible for atypical scenarios. The Mudroom serves everyday use for the couple and their children, but is also easy to tidy up to receive guests, eliminating the need for two entries found in most homes. A workspace is conveniently located off the mudroom; it looks out on to the back yard to supervise the children and can be closed off with a sliding door when not in use. The Away Room opens up to the Living Room for everyday use; it can be closed off with its oversized pocket door for secondary use as a guest bedroom with en suite bath.
NET POSITIVE ENERGY. The all-electric home consumes 70% less energy than a code-built house, and with measured energy data produces 48% more energy annually than it consumes, making it a 'net positive' home. Thick walls and roofs lack thermal bridging, windows are high performance, triple-glazed, and a continuous air barrier yields minimal leakage (0.27ACH50) making the home among the tightest in the US. Systems include an air source heat pump, an energy recovery ventilator, and a 13.1kW photovoltaic system to offset consumption and support future electric cars.
ACTUAL PERFORMANCE. -6.3 kBtu/sf/yr Energy Use Intensity (Actual monitored project data reported for the firm’s 2016 AIA 2030 Commitment. Average single family home is 52.0 kBtu/sf/yr.)
o 10,900 kwh total consumption (8.5 kbtu/ft2 EUI)
o 16,200 kwh total production
o 5,300 kwh net surplus, equivalent to 15,000-25,000 electric car miles per year. 48% net positive.
WATER EFFICIENCY. Plumbing fixtures and water closets consume a mere 60% of the federal standard, while high efficiency appliances such as the dishwasher and clothes washer also reduce consumption rates.
FOOD PRODUCTION. After clearing all invasive species, apple, pear, peach and cherry trees were planted. Future plans include blueberry, raspberry and strawberry bushes, along with raised beds for vegetable gardening. The house also offers a below ground root cellar, built outside the home's thermal envelope, to gain the passive benefit of long term energy-free food storage.
RESILIENCY. The home's ability to weather unforeseen challenges is predictable - it will fare well. The super-insulated envelope means during a winter storm with power outage, heat loss will be slow - taking days to drop to 60 degrees even with no heat source. During normal conditions, reduced energy consumption plus energy production means shelter from the burden of utility costs. Surplus production can power electric cars & appliances. The home exceeds snow & wind structural requirements, plus far surpasses standard construction for long term durability planning.

This modern green home offers both a vacation destination on Cape Cod near local family members and an opportunity for rental income.
FAMILY ROOTS. A West Coast couple living in the San Francisco Bay Area sought a permanent East Coast vacation home near family members living on Cape Cod. As academic professionals focused on sustainability, they sought a green, energy efficient home that was well-aligned with their values. With no green homes available for sale on Cape Cod, they decided to purchase land near their family and build their own.
SLOPED SITE. Comprised of a 3/4 acre lot nestled in the pines, the steeply sloping terrain called for a plan that embraced and took advantage of the slope. Of equal priority was optimizing solar exposure, preserving privacy from abutters, and creating outdoor living space. The design accomplished these goals with a simple, rectilinear form, offering living space on the both entry and lower/basement levels. The stepped foundation allows for a walk-out basement level with light-filled living space on the down-hill side of the home. The traditional basement on the eastern, up-hill side houses mechanical equipment and a home gym. The house welcomes natural light throughout, captures views of the forest, and delivers entertainment space that connects indoor living space to outdoor deck and dining patio.
MODERN VISION. The clean building form and uncomplicated finishes pay homage to the modern architectural legacy on the outer Cape. Durable and economical fiber cement panels, fixed with aluminum channels, clad the primary form. Cedar clapboards provide a visual accent at the south-facing living room, which extends a single roof plane to cover the entry porch.
SMART USE OF SPACE. On the entry level, the “L”-shaped living, dining, and kitchen space connects to the exterior living, dining, and grilling spaces to effectively double the home’s summertime entertainment area. Placed at the western end of the entry level (where it can retain privacy but still claim expansive downhill views) is the master suite with a built-in study. The lower level has two guest bedrooms, a second full bathroom, and laundry. The flexibility of the space—crucial in a house with a modest footprint—emerges in one of the guest bedrooms, which doubles as home office by opening the barn-style double doors to connect it to the bright, airy open stair leading up to the entry level. Thoughtful design, generous ceiling heights and large windows transform the modest 1,100 sf* footprint into a well-lit, spacious home. *(total finished space is 1800 sf)
RENTAL INCOME. The property works for its owners by netting rental income when the owners are home in San Francisco. The house especially caters to vacationers bound for nearby Mayo Beach and includes an outdoor shower adjacent to the lower level entry door. In contrast to the bare bones cottages that are typically available on the Cape, this home offers prospective tenants a modern aesthetic, paired with luxurious and green features. Durable finishes inside and out will ensure longevity with the heavier use that comes with a rental property.
COMFORT YEAR-ROUND. The home is super-insulated and air-tight, with mechanical ventilation to provide continuous fresh air from the outside. High performance triple-paned windows complement the building enclosure and maximize passive solar gain while ensuring a warm, draft-free winter, even when sitting close to the glass. A properly sized air source heat pump offers efficient heating & cooling, and includes a carefully designed the duct distribution system to provide even comfort throughout the house. The super-insulated envelope allows us to significantly reduce the equipment capacity, duct size, and airflow quantities, while maintaining unparalleled thermal comfort.
ENERGY EFFICIENT. The building’s shell and mechanical systems play instrumental roles in the home’s exceptional performance. The building enclosure reduces the most significant energy glutton: heating. Continuous super-insulation, thorough air sealing, triple-pane windows, and passive solar gain work together to yield a miniscule heating load. All active energy consumers are extremely efficient: an air source heat pump for heating and cooling, a heat pump hot water heater, LED lighting, energy recovery ventilation (ERV), and high efficiency appliances. The result is a home that uses 70% less energy than a similar new home built to code requirements.
OVERALL. The home embodies the owners’ goals and values while comprehensively enabling thermal comfort, energy efficiency, a vacation respite, and supplementary income.

This home remodel is a celebration of curves and light. Starting from humble beginnings as a basic builder ranch style house, the design challenge was maximizing natural light throughout and providing the unique contemporary style the client’s craved.
The Entry offers a spectacular first impression and sets the tone with a large skylight and an illuminated curved wall covered in a wavy pattern Porcelanosa tile.
The chic entertaining kitchen was designed to celebrate a public lifestyle and plenty of entertaining. Celebrating height with a robust amount of interior architectural details, this dynamic kitchen still gives one that cozy feeling of home sweet home. The large “L” shaped island accommodates 7 for seating. Large pendants over the kitchen table and sink provide additional task lighting and whimsy. The Dekton “puzzle” countertop connection was designed to aid the transition between the two color countertops and is one of the homeowner’s favorite details. The built-in bistro table provides additional seating and flows easily into the Living Room.
A curved wall in the Living Room showcases a contemporary linear fireplace and tv which is tucked away in a niche. Placing the fireplace and furniture arrangement at an angle allowed for more natural walkway areas that communicated with the exterior doors and the kitchen working areas.
The dining room’s open plan is perfect for small groups and expands easily for larger events. Raising the ceiling created visual interest and bringing the pop of teal from the Kitchen cabinets ties the space together. A built-in buffet provides ample storage and display.
The Sitting Room (also called the Piano room for its previous life as such) is adjacent to the Kitchen and allows for easy conversation between chef and guests. It captures the homeowner’s chic sense of style and joie de vivre.

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.”

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.”

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.

Lincoln Farmhouse
LEED-H Platinum, Net-Positive Energy
OVERVIEW. This LEED Platinum certified modern farmhouse ties into the cultural landscape of Lincoln, Massachusetts - a town known for its rich history, farming traditions, conservation efforts, and visionary architecture. The goal was to design and build a new single family home on 1.8 acres that respects the neighborhood’s agrarian roots, produces more energy than it consumes, and provides the family with flexible spaces to live-play-work-entertain. The resulting 2,800 SF home is proof that families do not need to compromise on style, space or comfort in a highly energy-efficient and healthy home.
CONNECTION TO NATURE. The attached garage is ubiquitous in new construction in New England’s cold climate. This home’s barn-inspired garage is intentionally detached from the main dwelling. A covered walkway connects the two structures, creating an intentional connection with the outdoors between auto and home.
FUNCTIONAL FLEXIBILITY. With a modest footprint, each space must serve a specific use, but also be flexible for atypical scenarios. The Mudroom serves everyday use for the couple and their children, but is also easy to tidy up to receive guests, eliminating the need for two entries found in most homes. A workspace is conveniently located off the mudroom; it looks out on to the back yard to supervise the children and can be closed off with a sliding door when not in use. The Away Room opens up to the Living Room for everyday use; it can be closed off with its oversized pocket door for secondary use as a guest bedroom with en suite bath.
NET POSITIVE ENERGY. The all-electric home consumes 70% less energy than a code-built house, and with measured energy data produces 48% more energy annually than it consumes, making it a 'net positive' home. Thick walls and roofs lack thermal bridging, windows are high performance, triple-glazed, and a continuous air barrier yields minimal leakage (0.27ACH50) making the home among the tightest in the US. Systems include an air source heat pump, an energy recovery ventilator, and a 13.1kW photovoltaic system to offset consumption and support future electric cars.
ACTUAL PERFORMANCE. -6.3 kBtu/sf/yr Energy Use Intensity (Actual monitored project data reported for the firm’s 2016 AIA 2030 Commitment. Average single family home is 52.0 kBtu/sf/yr.)
o 10,900 kwh total consumption (8.5 kbtu/ft2 EUI)
o 16,200 kwh total production
o 5,300 kwh net surplus, equivalent to 15,000-25,000 electric car miles per year. 48% net positive.
WATER EFFICIENCY. Plumbing fixtures and water closets consume a mere 60% of the federal standard, while high efficiency appliances such as the dishwasher and clothes washer also reduce consumption rates.
FOOD PRODUCTION. After clearing all invasive species, apple, pear, peach and cherry trees were planted. Future plans include blueberry, raspberry and strawberry bushes, along with raised beds for vegetable gardening. The house also offers a below ground root cellar, built outside the home's thermal envelope, to gain the passive benefit of long term energy-free food storage.
RESILIENCY. The home's ability to weather unforeseen challenges is predictable - it will fare well. The super-insulated envelope means during a winter storm with power outage, heat loss will be slow - taking days to drop to 60 degrees even with no heat source. During normal conditions, reduced energy consumption plus energy production means shelter from the burden of utility costs. Surplus production can power electric cars & appliances. The home exceeds snow & wind structural requirements, plus far surpasses standard construction for long term durability planning.

This Boulder, Colorado remodel by fuentesdesign demonstrates the possibility of renewal in American suburbs, and Passive House design principles. Once an inefficient single story 1,000 square-foot ranch house with a forced air furnace, has been transformed into a two-story, solar powered 2500 square-foot three bedroom home ready for the next generation.
The new design for the home is modern with a sustainable theme, incorporating a palette of natural materials including; reclaimed wood finishes, FSC-certified pine Zola windows and doors, and natural earth and lime plasters that soften the interior and crisp contemporary exterior with a flavor of the west. A Ninety-percent efficient energy recovery fresh air ventilation system provides constant filtered fresh air to every room. The existing interior brick was removed and replaced with insulation. The remaining heating and cooling loads are easily met with the highest degree of comfort via a mini-split heat pump, the peak heat load has been cut by a factor of 4, despite the house doubling in size. During the coldest part of the Colorado winter, a wood stove for ambiance and low carbon back up heat creates a special place in both the living and kitchen area, and upstairs loft.
This ultra energy efficient home relies on extremely high levels of insulation, air-tight detailing and construction, and the implementation of high performance, custom made European windows and doors by Zola Windows. Zola’s ThermoPlus Clad line, which boasts R-11 triple glazing and is thermally broken with a layer of patented German Purenit®, was selected for the project. These windows also provide a seamless indoor/outdoor connection, with 9′ wide folding doors from the dining area and a matching 9′ wide custom countertop folding window that opens the kitchen up to a grassy court where mature trees provide shade and extend the living space during the summer months.
With air-tight construction, this home meets the Passive House Retrofit (EnerPHit) air-tightness standard of

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.”
