The site is located in a gently reclined residential area. In order not to protrude from surroundings, the height is kept low and it declines along with the landscape. Each room can be separated by sliding doors, however usually it is a one large room, in which there are different kinds of spaces according to the height of ceilings, materials etc. It is also open to the courtyard, and corridor with skylights is almost an exterior space. The architecture, covered with a big sloping roof, unites the landscape.
