ZeroEnergy Design (ZED) created this modern home for a progressive family in the desirable community of Lexington. Thoughtful Land Connection. The residence is carefully sited on the infill lot so as to create privacy from the road and neighbors, while cultivating a side yard that captures the southern sun. The terraced grade rises to meet the house, allowing for it to maintain a structured connection with the ground while also sitting above the high water table. The elevated outdoor living space maintains a strong connection with the indoor living space, while the stepped edge ties it back to the true ground plane. Siting and outdoor connections were completed by ZED in collaboration with landscape designer Soren Deniord Design Studio. Exterior Finishes and Solar. The exterior finish materials include a palette of shiplapped wood siding, through-colored fiber cement panels and stucco. A rooftop parapet hides the solar panels above, while a gutter and site drainage system directs rainwater into an irrigation cistern and dry wells that recharge the groundwater. Cooking, Dining, Living. Inside, the kitchen, fabricated by Henrybuilt, is located between the indoor and outdoor dining areas. The expansive south-facing sliding door opens to seamlessly connect the spaces, using a retractable awning to provide shade during the summer while still admitting the warming winter sun. The indoor living space continues from the dining areas across to the sunken living area, with a view that returns again to the outside through the corner wall of glass. Accessible Guest Suite. The design of the first level guest suite provides for both aging in place and guests who regularly visit for extended stays. The patio off the north side of the house affords guests their own private outdoor space, and privacy from the neighbor. Similarly, the second level master suite opens to an outdoor private roof deck. Light and Access. The wide open interior stair with a glass panel rail leads from the top level down to the well insulated basement. The design of the basement, used as an away/play space, addresses the need for both natural light and easy access. In addition to the open stairwell, light is admitted to the north side of the area with a high performance, Passive House (PHI) certified skylight, covering a six by sixteen foot area. On the south side, a unique roof hatch set flush with the deck opens to reveal a glass door at the base of the stairwell which provides additional light and access from the deck above down to the play space. Energy. Energy consumption is reduced by the high performance building envelope, high efficiency mechanical systems, and then offset with renewable energy. All windows and doors are made of high performance triple paned glass with thermally broken aluminum frames. The exterior wall assembly employs dense pack cellulose in the stud cavity, a continuous air barrier, and four inches exterior rigid foam insulation. The 10kW rooftop solar electric system provides clean energy production. The final air leakage testing yielded 0.6 ACH 50 - an extremely air tight house, a testament to the well-designed details, progress testing and quality construction. When compared to a new house built to code requirements, this home consumes only 19% of the energy.

This LEED Platinum certified house reflects the homeowner's desire for an exceptionally healthy and comfortable living environment, within a traditional neighborhood. INFILL SITE. The family, who moved from another area of Wellesley, sought out this property to be within walking distance of the high school and downtown area. An existing structure on the tight lot was removed to make way for the new home. 84% of the construction waste, from both the previous structure and the new home, was diverted from a landfill. ZED designed to preserve the existing mature trees on the perimeter of the property to minimize site impacts, and to maintain the character of the neighborhood as well as privacy on the site. EXTERIOR EXPRESSION. The street facade of the home relates to the local New England vernacular. The rear uses contemporary language, a nod to the family’s Californian roots, to incorporate a roof deck, solar panels, outdoor living space, and the backyard swimming pool. ZED’s careful planning avoided to the need to face the garage doors towards the street, a common syndrome of a narrow lot. THOUGHTFUL SPACE. Homes with dual entries can often result in duplicate and unused spaces. In this home, the everyday and formal entry areas are one and the same; the front and garage doors share the entry program of coat closets, mudroom storage with bench for removing your shoes, and a laundry room with generous closets for the children's sporting equipment. The entry area leads directly to the living space, encompassing the kitchen, dining and sitting area areas in an L-shaped open plan arrangement. The kitchen is placed at the south-west corner of the space to allow for a strong connection to the dining, sitting and outdoor living spaces. A fire pit on the deck satisfies the family’s desire for an open flame while a sealed gas fireplace is used indoors - ZED’s preference after omitting gas burning appliances completely from an airtight home. A small study, with a window seat, is conveniently located just off of the living space. A first floor guest bedroom includes an accessible bathroom for aging visitors and can be used as a master suite to accommodate aging in place. HEALTHY LIVING. The client requested a home that was easy to clean and would provide a respite from seasonal allergies and common contaminants that are found in many indoor spaces. ZED selected easy to clean solid surface flooring throughout, provided ample space for cleaning supplies on each floor, and designed a mechanical system with ventilation that provides a constant supply of fresh outdoor air. ZED selected durable materials, finishes, cabinetry, and casework with low or no volatile organic compounds (VOCs) and no added urea formaldehyde. YEAR-ROUND COMFORT. The home is super insulated and air-tight, paired with high performance triple-paned windows, to ensure it is draft-free throughout the winter (even when in front of the large windows and doors). ZED designed a right-sized heating and cooling system to pair with the thermally improved building enclosure to ensure year-round comfort. The glazing on the home maximizes passive solar gains, and facilitates cross ventilation and daylighting. ENERGY EFFICIENT. As one of the most energy efficient houses built to date in Wellesley, the home highlights a practical solution for Massachusetts. First, the building enclosure reduces the largest energy requirement for typical houses (heating). Super-insulation, exceptional air sealing, a thermally broken wall assembly, triple pane windows, and passive solar gain combine for a sizable heating load reduction. Second, within the house only efficient systems consume energy. These include an air source heat pump for heating & cooling, a heat pump hot water heater, LED lighting, energy recovery ventilation, and high efficiency appliances. Lastly, photovoltaics provide renewable energy help offset energy consumption. The result is an 89% reduction in energy use compared to a similar brand new home built to code requirements. RESILIENT. The home will fare well in extreme weather events. During a winter power outage, heat loss will be very slow due to the super-insulated and airtight envelope– taking multiple days to drop to 60 degrees even with no heat source. An engineered drainage system, paired with careful the detailing of the foundation, will help to keep the finished basement dry. A generator will provide full operation of the all-electric house during a power outage. OVERALL. The home is a reflection of the family goals and an expression of their values, beautifully enabling health, comfort, safety, resilience, and utility, all while respecting the planet.

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 award-winning kitchen remodel proves that even the smallest spaces can deliver big on charm and functionality. Designed for a passionate home cook in a 1924 home, this under-100-square-foot kitchen embraces English Cottage style with thoughtful, space-maximizing details. Our favorite feature is the custom L-shaped glass-front cabinet wrapping the chimney chase - perfect for showcasing cookbooks, canisters, and plants. The workstation sink extends usable prep space, while the two-tier cutlery drawer and drawer-within-a-drawer system keep essentials organized. Paired with brick-look porcelain tile in a herringbone pattern, this cozy, character-rich kitchen honors the home’s history while meeting every modern need.

In this farmhouse inspired bathroom there are four different patterns in just this one shot. The key to it all working is color! Using the same colors in all four, makes this bath look cohesive and fun, without being too busy. The gold in the accent tile ties in with the gold in the wallpaper, and the white ties all four together. By keeping a neutral gray on the wall and vanity, the eye has time to rest making this bath a real stunner!

This is another complete remodel. Almost everyone has a home with a bathtub that can be converted, such as this space, "More and more people prefer larger showers to shower-tub combinations. This layout is a very common builder layout, too." We just luxed it up by adding a curbless shower, this means the shower floor is level with the main floor in the bathroom, no step up to get in. We also installed a liner drain! The client wanted modern and white. The tile design in the shower is stainless steel pebble tile on the wall cut in on a curve, along with a white glossy tile that has a metal reveal running horizontal. The same tile is contentious throughout bathroom. We tiled all the walls in the bathroom from floor to ceiling. Note the linear drain too.

With adjacent neighbors within a fairly dense section of Paradise Valley, Arizona, C.P. Drewett sought to provide a tranquil retreat for a new-to-the-Valley surgeon and his family who were seeking the modernism they loved though had never lived in. With a goal of consuming all possible site lines and views while maintaining autonomy, a portion of the house — including the entry, office, and master bedroom wing — is subterranean. This subterranean nature of the home provides interior grandeur for guests but offers a welcoming and humble approach, fully satisfying the clients requests. While the lot has an east-west orientation, the home was designed to capture mainly north and south light which is more desirable and soothing. The architecture’s interior loftiness is created with overlapping, undulating planes of plaster, glass, and steel. The woven nature of horizontal planes throughout the living spaces provides an uplifting sense, inviting a symphony of light to enter the space. The more voluminous public spaces are comprised of stone-clad massing elements which convert into a desert pavilion embracing the outdoor spaces. Every room opens to exterior spaces providing a dramatic embrace of home to natural environment. Grand Award winner for Best Interior Design of a Custom Home The material palette began with a rich, tonal, large-format Quartzite stone cladding. The stone’s tones gaveforth the rest of the material palette including a champagne-colored metal fascia, a tonal stucco system, and ceilings clad with hemlock, a tight-grained but softer wood that was tonally perfect with the rest of the materials. The interior case goods and wood-wrapped openings further contribute to the tonal harmony of architecture and materials. Grand Award Winner for Best Indoor Outdoor Lifestyle for a Home This award-winning project was recognized at the 2020 Gold Nugget Awards with two Grand Awards, one for Best Indoor/Outdoor Lifestyle for a Home, and another for Best Interior Design of a One of a Kind or Custom Home. At the 2020 Design Excellence Awards and Gala presented by ASID AZ North, Ownby Design received five awards for Tonal Harmony. The project was recognized for 1st place – Bathroom; 3rd place – Furniture; 1st place – Kitchen; 1st place – Outdoor Living; and 2nd place – Residence over 6,000 square ft. Congratulations to Claire Ownby, Kalysha Manzo, and the entire Ownby Design team. Tonal Harmony was also featured on the cover of the July/August 2020 issue of Luxe Interiors + Design and received a 14-page editorial feature entitled “A Place in the Sun” within the magazine.
