An original 1930’s English Tudor with only 2 bedrooms and 1 bath spanning about 1730 sq.ft. was purchased by a family with 2 amazing young kids, we saw the potential of this property to become a wonderful nest for the family to grow.
The plan was to reach a 2550 sq. ft. home with 4 bedroom and 4 baths spanning over 2 stories.
With continuation of the exiting architectural style of the existing home.
A large 1000sq. ft. addition was constructed at the back portion of the house to include the expended master bedroom and a second-floor guest suite with a large observation balcony overlooking the mountains of Angeles Forest.
An L shape staircase leading to the upstairs creates a moment of modern art with an all white walls and ceilings of this vaulted space act as a picture frame for a tall window facing the northern mountains almost as a live landscape painting that changes throughout the different times of day.
Tall high sloped roof created an amazing, vaulted space in the guest suite with 4 uniquely designed windows extruding out with separate gable roof above.
The downstairs bedroom boasts 9’ ceilings, extremely tall windows to enjoy the greenery of the backyard, vertical wood paneling on the walls add a warmth that is not seen very often in today’s new build.
The master bathroom has a showcase 42sq. walk-in shower with its own private south facing window to illuminate the space with natural morning light. A larger format wood siding was using for the vanity backsplash wall and a private water closet for privacy.
In the interior reconfiguration and remodel portion of the project the area serving as a family room was transformed to an additional bedroom with a private bath, a laundry room and hallway.
The old bathroom was divided with a wall and a pocket door into a powder room the leads to a tub room.
The biggest change was the kitchen area, as befitting to the 1930’s the dining room, kitchen, utility room and laundry room were all compartmentalized and enclosed.
We eliminated all these partitions and walls to create a large open kitchen area that is completely open to the vaulted dining room. This way the natural light the washes the kitchen in the morning and the rays of sun that hit the dining room in the afternoon can be shared by the two areas.
The opening to the living room remained only at 8’ to keep a division of space.

This 5,800-square-foot mass timber cottage sits on Lake of the Woods, Ontario, built directly on exposed granite bedrock with epoxy-anchored foundations. The structural system uses prefabricated Nordic laminated beams, columns, and cross-laminated timber panels — the CLT roof deck serves as both the structural diaphragm and the finished interior ceiling, eliminating the need for added ceiling framing and keeping the profile clean and slim. Long spans between columns open up the lake-facing glazing without obstruction, while large cantilevered roof overhangs define the exterior silhouette. 3 bedrooms, 3 bathrooms, designed by Nelson Architecture Inc., completed 2018.

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.”

Aesthetic Value: The freestanding stairway features extensive stringer details. Compound transitions for several moulding details and handrail provide continuous flow of the stringers and balustrade from the cylinders at the bottom throughout the stair and balconies.
Stair Safety: The project required spanning of greater run than normal. Additional treads and risers were added to create a nice rise to run ratio for a more comfortable stride at the walk path.
Quality of Workmanship: Seamless joinery of mouldings throughout curves and transitions.
Technical Challenge: Designing a stair that laid out to fit the well and span. Providing sufficient structure in the freestanding stairway to tie into the floating 2nd floor at the top of the stair.

This project was as exciting as it was challenging. The Owner directive was to open up a functional but very choppy master bathroom, creating an open plan, classicly finished master bath.
The home owner wanted the elegant, freestanding tub and chandelier to be the focal point...presenting the challenge. When in use, the tub creates a 1,200 lb point load in the middle of an 18' span, directly over a formal living room below.
In order to solve this, we supplemented the existing joists, with 14' steel plates, from end to end. This allowed the tub to be suspended, mid span, and provide the owner with the focal point that they were looking for.
Opposite the tub, is an incredible walk in shower, formerly, a closet.
The contrast of the chrome Kohler fixtures and the extensive Carerra White marble create a wonderful escape for our client...

An original 1930’s English Tudor with only 2 bedrooms and 1 bath spanning about 1730 sq.ft. was purchased by a family with 2 amazing young kids, we saw the potential of this property to become a wonderful nest for the family to grow.
The plan was to reach a 2550 sq. ft. home with 4 bedroom and 4 baths spanning over 2 stories.
With continuation of the exiting architectural style of the existing home.
A large 1000sq. ft. addition was constructed at the back portion of the house to include the expended master bedroom and a second-floor guest suite with a large observation balcony overlooking the mountains of Angeles Forest.
An L shape staircase leading to the upstairs creates a moment of modern art with an all white walls and ceilings of this vaulted space act as a picture frame for a tall window facing the northern mountains almost as a live landscape painting that changes throughout the different times of day.
Tall high sloped roof created an amazing, vaulted space in the guest suite with 4 uniquely designed windows extruding out with separate gable roof above.
The downstairs bedroom boasts 9’ ceilings, extremely tall windows to enjoy the greenery of the backyard, vertical wood paneling on the walls add a warmth that is not seen very often in today’s new build.
The master bathroom has a showcase 42sq. walk-in shower with its own private south facing window to illuminate the space with natural morning light. A larger format wood siding was using for the vanity backsplash wall and a private water closet for privacy.
In the interior reconfiguration and remodel portion of the project the area serving as a family room was transformed to an additional bedroom with a private bath, a laundry room and hallway.
The old bathroom was divided with a wall and a pocket door into a powder room the leads to a tub room.
The biggest change was the kitchen area, as befitting to the 1930’s the dining room, kitchen, utility room and laundry room were all compartmentalized and enclosed.
We eliminated all these partitions and walls to create a large open kitchen area that is completely open to the vaulted dining room. This way the natural light the washes the kitchen in the morning and the rays of sun that hit the dining room in the afternoon can be shared by the two areas.
The opening to the living room remained only at 8’ to keep a division of space.
