A residence for a family of three in a residential area in Tokyo. The first floor houses the private rooms and water supply, while the second floor is a large one-room living and dining room. The ceiling and floor height are changed in this large, light-filled room, creating a structure in which each place defines its own way of life. The living/dining room has a pit, a space where one can sit on the floor and relax, a small terrace on the second floor, and a large roof terrace on the third floor, allowing one to change the place to relax according to one's mood. In keeping with the lifestyle of the client, who often invites people over, all the places are visible from their respective locations, and the intention was to create a lively atmosphere. The dwelling, which sits on a corner lot, is subject to diagonal restrictions from three directions together with the north side. In response to this restriction, by making the roof HP-curved (hyperbolic), we were able to create a space with movement while maintaining a simple structural frame and good workability.
