It’s not easy to transform a 15-foot-wide building site—wedged between houses in every direction—into a home that feels more spacious than its location allows. Mamm-design’s solution was to dedicate two-thirds of this tiny 653-square-foot house in Tokyo to a 20-foot-high garden room to bring a sense of the outdoors in. A centrally positioned evergreen ash anchors the airy terrace, which is paved with complementary gray bricks. The kitchen, bedroom, bathroom, and workspace are all connected to the central space, transforming the covered veranda into a surrealistic theatrical setting for day-to-day life.

It’s not easy to transform a 15-foot-wide site (wedged between houses in every direction) into a home that feels spacious. Tokyo-based firm Mamm-design’s solution was to dedicate two-thirds of the 653-square-foot residence into a central garden room. The kitchen, bedroom, bath, and home office are all connected to a gray-brick terrace, which is anchored by an evergreen ash tree.
