This is a residence and atelier for a couple in the center of Tokyo. The building area is small, because of its size and flag shape. It needed to design the house using effectively height direction, so we designed the house as a bookshelf. The floors like bookshelf plates are placed at the different level in the deformed box. And furniture is put on the each shelf-floor to create living room, dining room, kitchen and bedroom. In the big volume, floating life places expand with 360 degree view. Life places are connected each other in and out of shadow varying distance in tree dimension. This means life places are opened planar and cross-sectional, while they are divided. Concerning structural aspect, each shelf-floor is hooked up to the shelf-frame, which composed of columns and beams three-dimensionally. This structure system gives latitude for space composition. And the shelf frame works not only as the structural parts but also as the fixture supporting life places. On one place it is used as handrail or threshold, on the other place it is used as book-shelf or wardrobe. The way of using depends on the situation. Lightings hung from top of the box till the each floors to illuminate them such as a floating stage. The daily life itself is stored on a small residence like big furniture.
Concerning function of this house, it can be divided into 3 parts in terms of height direction, “atelier (working area), living area and loft area”. The each atelier for husband and wife are arranged at 1st floor to easily deal with visitor. The 2nd floors composed with four book shelves are assumed a role of living area. The loft area is above of living area. It is like a catwalk. Here is used as reading space, storage and so on. In the site surrounding by next building changing the height level means changing environment such as sunlight, well ventilated and view in the house. The resident are enable to enjoy it according to their life.
