The house is built on a 1.5M grid module in all XYZ directions. This site is at a corner of the new residential area in Kawasaki-shi, Kanagawa, Japan. The space is composed of a solid cube of 9.0M x 9.0M x 6.0M and a cubic void of 4.5M x 4.5M x 6.0M.
The hall, children's room, kitchen are laid out to surround the living-dining room on the ground floor. On the first floor, the bedroom, walk-in closet, bathroom, courtyard, are laid out to surround the double floor-height well which is 6.0M.
Each room of the interior space is connected through the void of the living room. And the void cuts off the sky as a geometric form, letting the sunlight inside. In this house, all events, the changes of the seasons, course of time, and human activity, are created through the void.
