This is a house built in the central portion of the city in Hokkaido. The neighboring house approaches the next ground very limit borderline on the housing complex and the east side of seven stories, and there is a building of the tax office not used now in the west side in the south. A multistory housing complex will be expected to be built to this tax office in the future. In such "State", the design was advanced aiming to give a steady space to the person who lived. It spaces it though it is quiet and steady without blockading agreeable. The house has been designed in the place named [orudosu] of the Inner Mongolia autonomous region before. As for it, a house big as for surroundings was scheduled to be built in the one of making big construction in the division that had been greatly sold in lots. In addition, I thought that I felt the severity in the ambient surrounding including the climatic condition, made the buffer zone, and found an internal space of a steady secret room. The state of this site started finding the necessity in this place feeling that there were a lot of common features with [orudosu], and succeeding to the idea. The necessity of making an open mouth on the wall to the outside is not felt when thinking, and it thinks about the state of a space near the secret room. The outside and it spaces it as well as [orudosu] only according to a top light the room with the high ceiling of relations. It is such a space where the sense of distance of person's "Whereabouts" and "Empty" becomes a buffer zone.
