This house is for a young couple allocated in a residential area near the sea in Oiso. The site is quite large for living by two persons, and their wish was very simple, to have one big space except for a small bedroom. We thought we should explore “the bigness” and develop the potential of the site so that the client perceives the space bigger and feels spatially richer than the actual size.

Avoiding the ordinary layout of a house in long plot facing the northern road, which is squarish full wide volume in the center dividing carport and garden on south, we placed a slender full depth volume in the site. By stretching the circulation in full depth of the site we intended to let people walk through the site automatically and perceive physically the size of it. Also as the site is at the end of T-junction, we shifted the volume to east, and kept the west half as void space which is extended line of the road in order not to retain the air and wind flow, and to let the road extend into the site making contact to the public. Simultaneously we put the biggest roof possible by law over the site including the void space on west, so that the void space is not only the extension of public space but also the extension interior private space. The overlap of the translucent roof and the garden creates the interactive space which can accommodate diverse usage.

When you enter inside and look right from a bit closed and dim entrance, you find bright main living space which ceiling height is over 5m at the end of the corridor. At the opposite side, when you go up to the stairs, there is the master bedroom at intermediate level, then the study/guest room in which the dynamic wood framework of the roof in front of the view. When you look down the living room over the second floor which has pitched low ceiling like a loft, the contrast makes you feel the bigness and generosity of the air volume of this main space even more.

The exterior roof consists of H-shaped steel columns, laminated pine wood beams, and polycarbonate roofing. By minimizing the member of pillars, we intended the boundary of the garden between with and without the roof becomes ambiguous. In opposite, we made the beam depth big to keep a good balance open-air and intimate atmosphere. For interior, we selected light gray finish and materials in order that people may perceive its geometry abstract and gradational light coming in from outside.

Often people say that the bigger the space, the richer the space. If the project is in the center of a metropolitan, it may be the status to have a big room in terms of area. But in the case a big site is already out there, we thought just to make a big room in the middle of the site isn’t enough to feel the bigness and the richness. This house is an attempt to acquire “the bigness” beyond an ordinary big room by carefully reading the context of the site, laying out and shaping the volume of the house, creating the intermediate space as extension of both public and private, and selecting materials to enforce all of those intentions.
