‘ma house’ occupies an incredibly narrow plot of land in a densely populated residential region of okazaki, japan. reinterpreting traditional notions of scale and program, the dwelling, created by katsutoshi sasaki + associates, utilizes the full length of its 21 meter site to establish a functional and effective family home.

internally, all volumes are a maximum of 3 meters in width, with the height of each space dependent on its function and the number of occupants it may have at any one time. additionally, rooms designed for single occupancy feature limited natural light, whereas communal areas of the house are brighter and more generously proportioned.

dispersed living quarters result in unrestricted flexible volumes, which can accommodate more than one program. this efficient use of the minimal floor space is evidenced through the scheme’s corridor, which also functions as a study area. in addition to a internal garden at ground floor level, a roof terrace provides private an external sundeck and a connection with the natural environment.
