Wild View Farm includes a new “Forever home” (we deconstructed an existing house with a 90% landfill diversion rate), and enhancements to several working barns. The 80 acre site was an original homestead farm from the 1890’s. Both its buildings and soil had become severely degraded. The owners are working to holistically restore this property and make it a model of modern regenerative farming. They are planting hundreds of trees, re-introducing livestock and working with Dryland Agroecology Research and High Plains Permaculture to restore the soil.
The -51 HERS rated home is not just energy-efficient - it’s a model of “Regenerative design”. The deep green house design included multiple challenges – foremost was how to create a Passive Solar design that also took full advantage of the massive views to the West. We solved it with an L shaped building that optimized passive and active solar strategies on the south face, then actively protected the western facade with a giant covered porch and tuned glazing. The home’s leading-edge energy package includes a Ground source heat pump, a large roof-mounted solar PV array, battery back-up, EV chargers, and Energy Recovery Ventilator (ERV), Energy Star Appliances and windows, a robust foam insulation shell and LED lighting.
We also endeavored to craft a modern day interpretation of the farmhouse typology, with a low-slung simple gable-roofed form that would feel like it’s always been there. The exterior material palette of limestone, cementitious stucco and heavy timber gives it a rich Colorado Modern Farmhouse feel. The home is full of custom details like walls of vaulted glass to capture the sweeping mountain views, an AI Smart Home control system, a sleeping loft for kids and guests, a hard-working Butler’s Pantry, a gourmet outdoor kitchen, a pool & spa, a cozy office nook for reading, and a lovely built-in bench for morning coffee. Phase 2 of this project will include a Farmworker ADU and a full renovation of the existing historic barn.

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.”

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.”

This custom 2588 sq. ft. home includes 3 bedrooms,
2.5 bath, home office, piano recital room, and large
3 car garage in a compact footprint. It is South-East
Boise’s first net-zero energy home achieving a Home
Energy Rating Score (HERS) of zero.
The purpose of the project is to demonstrate that
every urban home can be designed and built healthy,
energy efficient, durable, and beautiful… in general
extremely sustainable.
Long roof overhangs shade the windows from direct
sunlight, while the high windows allow light to
penetrate deep into the home. The home was oriented
to optimize the amount of solar gain and capture the
most solar energy throughout the day.
While this residence has high-tech features and
details, it is a warm, comfortable atmosphere that
welcomes all that enter.
Sustainable living is achieved through a variety of ways,
but the most notable upon visiting is the landscaping.
The landscape has drought tolerant plants that thrive
in our high desert environment and a large garden
supplies food for the residences all season long. This
home is a truly sustainable example of what modern
urban development should be about.

The Spinalssage JetPak is a simple, yet highly effective massage. Each of the 2 rotating jets are positioned to align with points along the spine where tension can build and be stored. The pulsating sensation is simple, yet very therapeutic and relaxing. In addition, because this JetPak uses less water flow than most, it can also be used to optimize water flow rates to your other JetPaks across the spa.

Wild View Farm includes a new “Forever home” (we deconstructed an existing house with a 90% landfill diversion rate), and enhancements to several working barns. The 80 acre site was an original homestead farm from the 1890’s. Both its buildings and soil had become severely degraded. The owners are working to holistically restore this property and make it a model of modern regenerative farming. They are planting hundreds of trees, re-introducing livestock and working with Dryland Agroecology Research and High Plains Permaculture to restore the soil.
The -51 HERS rated home is not just energy-efficient - it’s a model of “Regenerative design”. The deep green house design included multiple challenges – foremost was how to create a Passive Solar design that also took full advantage of the massive views to the West. We solved it with an L shaped building that optimized passive and active solar strategies on the south face, then actively protected the western facade with a giant covered porch and tuned glazing. The home’s leading-edge energy package includes a Ground source heat pump, a large roof-mounted solar PV array, battery back-up, EV chargers, and Energy Recovery Ventilator (ERV), Energy Star Appliances and windows, a robust foam insulation shell and LED lighting.
We also endeavored to craft a modern day interpretation of the farmhouse typology, with a low-slung simple gable-roofed form that would feel like it’s always been there. The exterior material palette of limestone, cementitious stucco and heavy timber gives it a rich Colorado Modern Farmhouse feel. The home is full of custom details like walls of vaulted glass to capture the sweeping mountain views, an AI Smart Home control system, a sleeping loft for kids and guests, a hard-working Butler’s Pantry, a gourmet outdoor kitchen, a pool & spa, a cozy office nook for reading, and a lovely built-in bench for morning coffee. Phase 2 of this project will include a Farmworker ADU and a full renovation of the existing historic barn.

This project serves as a premier example of how two high-performance building systems can be integrated to achieve a unique architectural aesthetic. The standing seam roof provides a durable, sleek landscape for the strategic placement of premium skylights, drawing natural light into the luxury cabins and condominiums at the Mountain Lodge Telluride ski-in/ski-out resort.
The Horn Brothers Roofing team demonstrated exceptional logistical coordination, executing the installation of approximately 1,000 squares (100,000 sq. ft.) of 24-gauge, 1.5" Mechanical Lock Standing Seam within a rigorous six-month window. Complementing the rustic log architecture, Quantum Daylite Solutions facilitated the selection of 75 VELUX skylights, featuring custom stain-grade wood interiors for a seamless indoor-outdoor feel.
From a performance standpoint, this is a highly robust system. The interlocking panels provide a superior barrier against water infiltration and carry a Class A fire rating, ensuring long-term durability and solar thermal protection. To optimize the building envelope, Boston Vents deliver high-volume ventilation that matches the roof’s sharp geometric profile, while integrated snow fences provide a critical defense against ice and snow shedding during the heavy winter months.
Despite the environmental challenges of a high-altitude project, the Horn Brothers Roofing team ensured a successful completion before the first snowfall. This achievement stands as a testament to the specialized skill and collaboration of everyone involved in the process.
