One of our clients is the founder and director of Triangle Modernist Houses, an award-winning, non-profit organization that documents, preserves and promotes modernist residential design. Naturally, he and his wife wanted a modern house. But they didn’t want to leave their old neighborhood. Then, on one of their daily walks in the neighborhood, they found a 40-year-old structure for sale. The indistinct house was beyond repair, but it occupied a promising lot with a southeast exposure to a beautiful lake. This gave the couple the idea to build their “home and vacation home at the same time,” as they said.The design of the new house addresses two key site relationships: (1) the existing neighborhood and its contextual scale, and (2) the landscape of the lake. From the street, the new one-story house’s form is low, quiet, and horizontal, with the only real opening towards the street at the main entrance porch. Because this house would be a dramatic departure from the typical houses in the neighborhood, we sited it deeply into the property. The 2,400-square-foot house opens up to its surroundings at the back, where extensive glazing provides constant views of the lake and surrounding natural environment. This approach maximizes the interior connection to the outdoors without sacrificing the clients’ privacy.Programmatically, the house features: an entrance foyer; an open living/dining/kitchen space suitable for entertaining, especially with access to the deck from this space; a master bedroom suite with two separate bathrooms and walk-in closets; two generous office spaces; a guest room and additional bath; and a two-car garage. Square concrete “steps” lead from the driveway to the front porch. A wooden deck spans the lakefront elevation. As both the architect and contractor, Tonic’s challenge was to maximize the view of the lake from the open “public” space (living/dining/kitchen area), while providing the clients with an energy-efficient and comfortable living space. The solution came in the form of a hockey stick-shaped roof structure fabricated of wood beams and steel plate. This composite structure, designed with the help of the North Carolina Solar Center, supports an IPE pipe trellis. The form and composition ensure that the sun’s harsh rays are blocked in the warm summer months, while the lower winter sun is allowed to penetrate and warm the interior. A band of clerestory windows above the main living space, facing the street, allow more natural light to penetrate the interior and creates a glow above the horizontal structure at night.To achieve a construction budget of $180 per square foot as requested by the clients, the building methods used in the house are standard, off-the-shelf materials that have been reinterpreted and used in inventive ways, such as the “pin stripe” siding that creates horizontal detailing for the street-facing façade.
