Located in an exclusive Tokyo neighborhood defined by gracious, tree-lined avenues, the modest wood-shuttered house designed by the Tokyo firm TNA is a Maison Domino structure with a twist. Like Le Corbusier’s conceptual model, it consists of simple slabs and columns. While the piloti elevate the building above the ground, a spiraling ramp wraps its perimeter, seamlessly stitching all of its levels together in one tidy package—without any stairs.
Named Helix House by the architects, the project began with a cold call from the clients, a couple with three school-age children. Impressed with an earlier TNA home, Ring House (RECORD, April 2007, page 106), they contacted the husband-and-wife firm, hoping to build something on their newly purchased 1,875-square-foot plot. Many of the area’s old houses no longer exist, but unusually strict building codes help maintain a distinctive character for the community.
