To expand the home’s livability, we built a ground-up addition for the extended living room. This warm, inviting space features brick ribbon-accented hardwood floors, paired with cypress accents on both the ceiling and floors for natural character. The centerpiece is the white oak flooring, bringing balance and a sense of continuity throughout the room.

We were worried that the house would get too long looking, so we changed direction of the rooflines and made it look like a New England farmhouse with attached barn.

New flooring, new paint, and new lighting throughout this home, provided a fresh canvas to make this home their own. The kitchen renovation involved extending and expanding two work areas, one a peninsula and the other the island with an attached table. The original flow through the kitchen made the extended island with the table an ideal problem resolution and the perfect place for grandkids to gather for snacks and games. The perimeter cabinets were painted an off-white and the green island spoke to my client's love of green and her California roots. Durable quartz countertops and subway tile backsplash provided the perfect canvas for countless family gatherings. The living room also had a custom built-in with a bench added for their many books and collections.

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.”

Perched on a ridge at the edge of a wooded expanse, this mid-century modern home was designed to embrace both the intimate connection to the forest and the expansive valley views beyond. The site—carefully chosen from the family’s 52-acre homestead in western Wisconsin—balances privacy and openness, placing the home at the meeting point of dense trees and rolling fields.
The approach winds through the forest, offering only glimpses of the structure. Upon arrival, the parking area is subtly positioned below the main level, reinforcing the sense of discovery. As one ascends the entry walk, the house unfolds, revealing a dramatic view through the two-story living space, anchored by a brick fireplace that extends from floor to ceiling. The asymmetrical roofline lifts upward, accentuating the openness and maximizing natural light.
Inside, warm materials define the interiors. Wood ceilings and floors, complemented by concrete-look tile, establish a natural, grounded aesthetic. Black wood-clad beams provide scale and structure, subtly delineating spaces within the open-plan layout. A wood lattice screen partially conceals the dining area from the foyer, offering both openness and privacy. The kitchen—designed for gathering—features a large island, a dedicated baking station, and a breakfast counter that catches morning light while serving as a pass-through to the adjacent patio. Two textured glass sliding panels allow the kitchen to be closed off when needed. Just beyond, a hidden gem: the home’s personal Tiki room, complete with a vintage mug collection and a full bar.
To the east, the central fireplace marks the transition to more intimate spaces. A wide stair, integrated with the hearth, leads to the lower level, while a library with a corner window creates a quiet retreat, perfect for reading and taking in the valley beyond. The primary suite extends off this wing, featuring a spa-like bath with a textured tile walk-in shower, a soaking tub positioned for dramatic views, and a private balcony overlooking the landscape.
The lower level is designed for family gatherings and extended stays. A secondary fireplace, echoing the materials of the main level, anchors a cozy living area with an adjacent kitchenette. Additional bedrooms and baths provide ample accommodations, while a hidden playhouse under the stair and a dedicated bunk room add playful touches for visiting grandchildren.
The home is a balance of openness and enclosure, modernity and warmth—designed not only as a retreat but as a multigenerational gathering place, deeply connected to the land.

This young family began working with us after struggling with their previous contractor. They were over budget and not achieving what they really needed with the addition they were proposing. Rather than extend the existing footprint of their house as had been suggested, we proposed completely changing the orientation of their separate kitchen, living room, dining room, and sunroom and opening it all up to an open floor plan. By changing the configuration of doors and windows to better suit the new layout and sight lines, we were able to improve the views of their beautiful backyard and increase the natural light allowed into the spaces. We raised the floor in the sunroom to allow for a level cohesive floor throughout the areas. Their extended kitchen now has a nice sitting area within the kitchen to allow for conversation with friends and family during meal prep and entertaining. The sitting area opens to a full dining room with built in buffet and hutch that functions as a serving station. Conscious thought was given that all “permanent” selections such as cabinetry and countertops were designed to suit the masses, with a splash of this homeowner’s individual style in the double herringbone soft gray tile of the backsplash, the mitred edge of the island countertop, and the mixture of metals in the plumbing and lighting fixtures. Careful consideration was given to the function of each cabinet and organization and storage was maximized. This family is now able to entertain their extended family with seating for 18 and not only enjoy entertaining in a space that feels open and inviting, but also enjoy sitting down as a family for the simple pleasure of supper together.

If you want a dining table that has a simple yet elegant design then this table made from oak wood is perfect for your home. The table has simple lines that help in providing a sophisticated and stylish look.
The dinning has wooden legs that are pretty solid.
It also has extensions that are of the same color.
