klein dytham architecture: sasao house

a few blocks from the high-rises of shinjuku within the backstreets of a neighborhood in tokyo, japan is the ‘sasao house’, a residence and restaurant completed by tokyo-based practice klein dytham architecture. resembling origami, the faceted exterior is surfaced with a layer of trapezoidal metal shingles, maintaining a crisp white appearance within the surrounding context of brown and gray structures. during the annual matsuri festival, the elevation serves as a blanched backdrop for the colorful floats which participate in the parade.

addressing the corner site, a restaurant run by the homeowner is on the ground level with the family’s parents living in a unit on the second floor, and double-storey lofted residences located on the second and third levels. the interior continues the clean white palette except for one partition surfaced with vividly colored wallpaper, reflecting the dweller’s personality. a sloping roof creates a cave-like atmosphere while large windows and terraces introduce abundant daylight into the space.
