The homeowners envisioned a design where the house wraps around an open courtyard, seamlessly blending indoor and outdoor living. The primary goal was to ensure the main living area, outdoor spaces, and pool all face the stunning view. With a love for capturing sunsets and hosting gatherings, the home was built for entertaining, featuring expansive open spaces and a strong connection between the interior and exterior. A separate wing provides the teenagers with privacy, while the open courtyard maintains a visual connection due to the open courtyard. The spacious kitchen flows effortlessly into the dining and living areas, creating a large, open-concept layout perfect for family and guests.

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

This home sits at a dramatic juncture between a state highway and the Columbia River, adjacent to the Lewis and Clark Scenic Byway. Steps away from its namesake, Steamboat Landing Park, the home has dramatic 180 degree views of the river, Mount Hood, and Oregon beyond. Creating a connection and celebrating this stunning natural setting while keeping highway noise at bay was one of this project's primary goals. Equally as important was the goal to design a high-performance building. These goals were met by implementing an energy-efficient heat pump system, radiant floor heating, 10" thick super-insulated concrete walls, closed-cell spray foam insulation in the attic, and triple-pane windows throughout. The sustainable attributes were balanced with durable and long-lasting materials, including standing seam metal roofing, stucco, and cedar siding to create a home that will stand for generations. Honoring the homeowner's request to design an age-in-place, one-level home, the plan is a simple sequence of bars with the two largest capped by gable roofs. The tallest of the bars closest to the highway is a garage, which houses the couple's much-loved Airstream. A smaller flat-roofed bar acts as a connector between the gabled forms and serves as the home's entry with the kitchen functions beyond. The largest of the bars, and the one closest to the river, includes an open concept great room flanked by two-bedroom suites on either side. A water-front deck spans the entire living and dining area, with a twenty-foot wide multi-slide panel door offering a seamless connection to an outdoor covered entertainment area. Inside, smooth concrete floors, walnut casework, and multiple skylights combine to create a truly inviting space. Photographer: Matt Swain Photography

In this basement redesign, the primary goal was to create a livable space for each member of the family... transitioning what was unorganized storage into a beautiful and functional living area. My goal was create easy access storage, as well as closet space for everyone in the family’s athletic gear. We also wanted a space that could accommodate a great theatre, home gym, pool table area, and wine cellar.

This renovation was completed with the primary goal of removed the carpet in the stairs which was not only difficult to clean but constantly looking worn in this very busy household. Ideally they wanted a durable, low maintenance flooring solution that still added character and coziness. The solution: Luxury vinyl planks! The unique and discreet metal nosings we used respect the clean lines and richness of this amazing plank in a non-commercial way. NOTE: While not all vinyl planks are created equal - the good ones are worth paying a little extra for!

When we first met with our clients in their home, they had an outdated ‘’builder’s kitchen”. Even though it was open to adjacent spaces, the layout made it seem isolated from the rest of the house. As we worked on the design, making the space more sociable was among our primary goals. We opted for an island large enough for the entire family of four plus company (the original kitchen had a small peninsula that could only seat two). The gray color scheme, inspired by our clients’ bold decision to go with black appliances instead of traditional stainless steel, made a perfect backdrop for the stunning waterfall countertop. The end result was a very warm, inviting space that has now become the “new family room”. #phidesigninc #customkitchen #modernkitchen #kitchenrenovation #graykitchen #waterfallcountertop #quarz #marblecountertop #marblebacksplash #aventos #magiccorner #pullout #blackappliances #2017trend #satellitechandelier #hardwoodflooring #ravineviewconstruction

With a desire to stay close to friends and family, the owners of this 1984 home spent several years searching for property near their neighborhood to build a new, more modern, energy-conscious home tailored to their empty-nest lifestyle. They eventually concluded that their current site was the perfect location for them, but the home needed to be updated and reorganized to create fresh, open, unified spaces to comfortably welcome gatherings of family, friends, and guests. Before renovation, the floor plan included small rooms, dedicated hallways, a step-down living room, a heavy and dark corner fireplace, and limited opportunities for natural light and visual connections from space to space. Exterior deck areas were narrow, long, and used infrequently. Primary goals of this project included accessibility of space, more natural light, better connectivity between spaces, and a focus on sustainable performance. The updated main floor plan included the selective removal of walls to reallocate dedicated hall space to usable, open living area. The step-down living room was leveled for full accessibility, safety, furniture flexibility and overall space use. The removal of a half-height wall between the living area and the kitchen created continuity between the spaces. Reorganizing the primary entry and stair and eliminating walls between the entry and dining room created new visual connections between the kitchen and the entry. The new central concrete hearth and fireplace provides a strong, modern focal point for the living area. Large sliding glass doors on each side of the fireplace allow the TV area beyond to be separated from the living area as needed. In several strategic locations, the footprint of the house was expanded to enhance function and flow at the kitchen, dining room, and mudroom. The new outdoor deck area is now large and singular and includes a grille area, dining space and open seating overlooking the newly landscaped pool below. The exterior envelope of the house includes new insulation, siding, and energy-efficient windows, as well as two large roof-mounted solar arrays, to increase thermal performance and to offset energy costs. Inside, the new HVAC system maximizes energy efficiency while using a fraction of its former footprint. As a result, a portion of the former mechanical space was added back to the lower level family room area and expands into a cozy library nook. MMA partnered with the owner’s interior designer and kitchen designer to achieve a softer, contemporary palette of finishes that complement this newly configured, light-filled home.

The primary goal of the Ithaca II project was to open up the home to amplify natural light, bring outdoor views inside, and create a seamless indoor-outdoor flow. Additional updates refreshed the interiors with a focus on millwork and storage. The previous floor plan of this 1963 home carved up the main level into separate living, dining, family room and kitchen spaces that limited both sunlight and usable space for the way contemporary families live and entertain. By opening the layout and expanding the kitchen, the main floor instantly became more functional without disrupting the curved central staircase — an integral architectural element of the home. Adding a glass-inset front door, opening up exterior walls and incorporating wide folding glass doors instantly maximized natural light. In the all-new kitchen, maple cabinetry, a painted white island, quartz counters, backsplashes and appliances have created a space perfect for cooking and casual dining. The new accordion doors open both the adjacent dining area and living room to an expanded deck for seamless al fresco gatherings. Alpine Summit Homes added new four-inch white oak hardwood flooring to the main level. Trim molding was refreshed throughout the home with clean lines to add a modern look while maintaining the classic midcentury architectural roots. New storage cabinetry was added to the living room and powder/laundry room, while the primary suite received new doors and bathroom fixtures to match the main-level updates.

Energy Efficiency: Every effort has been utilized to reduce and minimize energy use through an effective strategy of both passive heating and cooling, as well as state-of-the-art active solar thermal and photovoltaic on site off-grid energy production. Optimal solar orientation with an attached thermal mass food production greenhouse on the Lower Floor enables hot air to be introduced into the house during the winter, and rise via. a thermal chimney “stack effect” and distributed throughout the house. In the summer the same thermal chimney is used to channel hot air to rise up to the Upper Loft vegetated Roof Terrace, where it is exhausted. This condition provides a positive air pressure in the Winter, and a negative pressure in the summer, drawing in cooler outside air from every open window. In addition carefully proportioned roof eave overhangs provide deep passive solar gain and additional day lighting in the winter, and cooling shade in the summer. Active mechanical systems include solar thermal which produces domestic hot water and is integrated into hydronic radiant heated floors. This is supplemented with a multi-split heatpump, on demand backup hot water, and an ERV, which collectively provide active heating, cooling, dehumidification, and healthful indoor air quality. The entire house and detached Barn are off-grid with a 14.4 kW solar array, whole-house batteries, and backup generator. Further, the home is super insulated and extremely tight with high energy performing windows and doors and LED lighting throughout, and even a high efficiency woodstove. Integrated Design: From the beginning and throughout construction, this home demonstrates a close collaboration between the Architect, Contractor, and Owners. Healthful materials and finishes standards, autonomy and energy efficiency, and environmental impact and sustainability were primary goals and stressed throughout. Careful attention was paid to finishes which will require minimal long term maintenance such as the galvalume metal roof (which also provides for rainwater harvesting) and fiber cement siding for longevity. Resource Efficiency / Conservation: Resource conservation began with Schematic Design which utilizes a 2 ft. grid of modular components, thereby optimizing construction efficiency and minimizing on site waste. The site was cleared with the trees stockpiled for future lumber harvesting and firewood. The foundation walls are “Ideal Walls” which use less than half the concrete of a conventional poured wall or block, and do not require extensive concrete footings, exterior insulation, or waterproofing. These panels are prefabricated off site and set in only a few days, which further reduces on site impact and construction lead time. Resiliency: Respect for climate change and mitigating its impact were primary considerations in the design and selection of materials and systems. The home is sited high on a south facing slope as protection from high water or flood and to optimize both passive and active solar opportunity. With remarkably tight construction and super insulation the interior is buffered from both outdoor heat and cold extremes. The metal roof and fiber cement siding are fireproof and resistant to the impact of high winds. And these materials are specified for minimal maintenance and longevity. Further, the attached Greenhouse and Upper Roof Terrace is landscaped and suitable for a vegetable garden with abundant sunshine, easy to water, and with no need for fencing to keep deer at bay. All this being a notable case study for Regenerative Design. Innovation: This home exemplifies Biophilic Design principles to facilitate symbiotic living in harmony with Nature. This incorporates careful attention to natural day lighting, indoor air quality, rainwater catchment and wastewater reclamation, garden food production with vegetated roofs, the home hearth and fire, and connected interaction with the weather and the surrounding natural ecosystems. Community Impact: This EcoHome project has already been presented at several Sustainable Building lectures as a model case study for “Green Building”, including USGBC at Brock Environmental Center in Virginia Beach, VA. Plans are underway for an Open House tour for area Architects and students.
