Context Norbert and Robin had dreamed of retiring in a Passive House-certified home overlooking the Lubberland Creek Preserve in Southeastern New Hampshire, and they’d done their homework. They were interested in using four integrated Zehnder America (www.zehnderamerica.com) technologies to make the 1,900 square foot home extremely energy efficient. They didn’t miss any opportunity to innovate or raise the bar on sustainable design. Our goals were focused on guaranteeing their comfort in every season, saving them money on a fixed income, and reducing the home’s overall impact on the environment as much as possible. Response The home faces directly south and captures sunlight all winter under tall and vaulted ceilings and a continuous band of slim-lined, Italian triple-pane windows and doors that provide gorgeous views of the wild preserve. A second-story office nook and clerestory provide even deeper views, with a little more privacy. Zehnder, which previously sold its innovative products only in Europe, took on the project as a test house. We designed around Zehnder’s vent-based systems, including a geothermal heat loop that heats and cools incoming air, a heat pump cooling system, electric towel-warmer radiators in the bathrooms, and a highly efficient energy recovery ventilator, which recycles heat and minimizes the need for air conditioning. The house effectively has no conventional heating system—and doesn’t need it. We also looked for efficiencies and smart solutions everywhere, from the lights to the windows to the insulation. The kitchen exhaust hood eliminates, cleans, and recirculates cooking fumes in the home’s unique kitchen, custom-designed to match the ways Norbert likes to prepare meals. There are several countertop heights so they can prep and clean comfortably, and the eat-in kitchen also has two seating heights so people can sit and socialize while they’re working on dinner. An adjacent screened porch greets guests and opens to the view. A roof-mounted solar system helps to ensure that the home generates more energy than it consumes—helped by features such as a heat pump water heater, superinsulation, LED lights and a polished concrete floor that helps regulate indoor temperatures.

The Yin-Yang House is a net-zero energy single-family home in a quiet Venice, CA neighborhood. The design objective was to create a space for a large and growing family with several children, which would create a calm, relaxed and organized environment that emphasizes public family space. The home also serves as a place to entertain, and a welcoming space for teenagers as they seek social space with friends. The home is organized around a series of courtyards and other outdoor spaces that integrate with the interior of the house. Facing the street the house appears to be solid. However, behind the steel entry door is a courtyard, which reveals the indoor-outdoor nature of the house behind the solid exterior. From the entry courtyard, the entire space to the rear garden wall can be seen; the first clue of the home’s spatial connection between inside and out. These spaces are designed for entertainment, and the 40 foot sliding glass door to the living room enhances the harmonic relationship of the main room, allowing the owners to host many guests without the feeling of being overburdened. The tensions of the house’s exterior are subtly underscored by a 12-inch steel band that hews close to, but sometimes rises above or falls below the floor line of the second floor – a continuous loop moving inside and out like a pen that is never lifted from the page, but reinforces the intent to spatially weave together the indoors with the outside as a single space. Scale manipulation also plays a formal role in the design of the structure. From the rear, the house appears to be a single-story volume. The large master bedroom window and the outdoor steps are scaled to support this illusion. It is only when the steps are animated with people that one realizes the true scale of the house is two stories. The kitchen is the heart of the house, with an open working area that allows the owner, an accomplished chef, to converse with friends while cooking. Bedrooms are intentionally designed to be very small and simple; allowing for larger public spaces, emphasizing the family over individual domains. The breakfast room looks across an outdoor courtyard to the guest room/kids playroom, establishing a visual connection while defining the separation of uses. The children can play outdoors while under adult supervision from the dining area or the office, or do homework in the office while adults occupy the adjacent outdoor or indoor space. Many of the materials used, including the bamboo interior, composite stone and tile countertops and bathroom finishes are recycled, and reinforce the environmental DNA of the house, which also has a green roof. Blown-in cellulose insulation, radiant heating and a host of other sustainable features aids in the performance of the building’s heating and cooling. The active systems in the home include a 12 KW solar photovoltaic panel system, the largest such residential system available on the market. The solar panels also provide shade from the sun, preventing the house from becoming overheated. The owners have been in the home for over nine months and have yet to receive a power bill.

Komfoo house interior designed by STUDIO KONDE Konrad Idaszewski Architekt, an interior architect from Poznań creating contemporary residential spaces that combine comfort, refined materials and a strong architectural character. Visit the full project: https://conde.pl/portfolio/gotowy-projekt-wnetrz-domu-komfoo/ Komfoo is part of the Modelowedomy collection of three individually configurable houses, conceived for different ways of living and distinct spatial arrangements. This comfortable house features a high living room with a mezzanine, while the kitchen and dining area are separated from the living space by a functional furniture wall. Contemporary living room designed as part of a modern house interior project in Poland, combining warm natural wood, soft beige upholstery, dark accents and carefully selected architectural details. Generous glazing brings greenery and daylight into the interior, while the high ceiling and elevated opening visible above the living zone emphasize the spacious character of the Komfoo house. The living area is centred around a large modular sectional sofa in a warm cream-beige fabric, composed of generously padded seats and broad chaise elements. Its soft, rounded profile creates a relaxed and comfortable seating arrangement, while several large cushions add to the informal character of the lounge. A textured light throw lies across the chaise, introducing another layer of softness and reinforcing the tactile quality of the neutral interior. Two overlapping round coffee tables form the centre of the seating arrangement, both finished in a deep black tone with vertically ribbed cylindrical bases. Their dark colour creates a strong contrast against the pale sofa and textured rug, while the different diameters give the composition a more dynamic, layered appearance. A small stack of books provides a discreet everyday detail on the smaller table. One of the strongest elements of this living room is the large feature wall finished with irregular natural timber panels. The individual pieces vary subtly in shape and orientation, creating a three-dimensional, textured surface that extends across the entire media wall. Set against this warm wood background, the large flat-screen television becomes a clearly defined focal point. Rather than being mounted directly to the wall, it stands on a slim black floor-supported structure, giving the media zone a lighter and more contemporary appearance. Natural timber flooring continues throughout the room, complementing the warm tones of the feature wall while contrasting with the pale woven rug beneath the seating area. The rug introduces a pronounced looped texture and visually gathers the sofa and coffee tables into one coherent lounge zone. Above, a large white cylindrical pendant suspended from a curved floor-to-ceiling arc provides a sculptural lighting element and adds a distinctive vertical accent to the otherwise restrained composition. Behind the seating area, a tall opening reveals the greenery outside and allows the garden to become part of the interior setting. The combination of the high living room, textured timber media wall, generous modular sofa, sculptural lighting and carefully balanced neutral palette gives the Komfoo interior a warm and sophisticated character. This approach reflects the work of STUDIO KONDE, an interior architect in Poznań developing contemporary, comfortable interiors as part of the Modelowedomy collection.
