Architect: Takeshi Hosaka Architects
Location: Yamanashi, Japan
Built year: 2009
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.
This building has no air conditioners. It is open to the air during most seasons, and people have a meal in the air like outside air.
For the lighting plan, Takeshi Hosaka Architects have determined such illumination as makes people simply feel changes in the evening light and does not make insects gather around the lights.
