Text description provided by the architects. This house has a composition of typical urban house in Tokyo. It is usually three-storey house with top portion cut off at an angle designated by height restriction code, in order to build the maximum allowable volume.
The first floor is allocated for garage, main entrance and two bedrooms. The second floor has a living room beneath the cutout portion along the street with skylight on the tilted ceiling, bathroom, kitchen and dining room. On the third floor is master bedroom, terrace, and void space in the middle that connects the second and the third floors.
The exterior facade is mostly closed on street side. Natural light enters from skylight to the second floor, and light well is provided to deliver natural light to the basement floor. Backside of the house is open towards the vacant lot behind the site, so you get open view from each floor.
Several contrasting textures and colors are used on both exterior and interior surfaces. On the exterior surfaces rough texture of concrete wall using plywood form, a wooden gate made of Japanese cedar, aluminum shutter and plaster are used. And on interior surface walnut flooring, plastered wall and ceiling, black sandstone, steel window sash are used. We carefully selected these materials so that the house will age beautifully and become more attractive and as time goes by.
