This building is similar to the inside and outside house we previously featured. The project was planned on the site with Mt. Fuji rising closely in the south and the two sides facing the trunk roads. Takeshi Hosaka Architects wanted this building to take on the characteristics of mountains and clouds. It is made from soft geometry, which are not derived from the figures like quadrangles and circles. By continuously operating innumerable polygon mesh points, Takeshi Hosaka Architects have determined the shape that clears the conditions such as the consistency as shell construction and the undulations that ward off rainwater in spite of its free geometry. The RC shell with cubic surfaces creates such spaces as 530 sqm, 140 sqm of kitchens, and 50 sqm of rest rooms, in such a manner that it envelops and opens them.
