A single-family house situated in suburbia of Tokyo. Instead of regarding a suburb as a subordinate of metropolis, this young couple’s suburban life could be truly centered by working more then three days a week from home. This change made us to come up with a new (or non-modern) house-type with the same budget as the neighboring mass-produced houses. The tiny nine square grid plan is applied, whose dimensioning is based on two kinds of modules in Japanese construction; 2430mm and 1820mm. 2430 x 3 = 1820 x 4 = 7280, the total width of this house. 2430 became the module of floors, and 1820 became the module of walls, dealing and playing with economy/convention of dimensions. The overall plan is made as a collective of fragmented places for different behaviors throughout the stacked grid.
