This is a cottage village planned on the premises of Hotel Sunvalley in Nasu City, Tochigi Prefecture. At first, the owner wanted to build a styrofoam dome house that we developed so that he could enjoy his stay even in winter. However, permission was not given because the site is in a national park. According to the Natural Parks Law, polygonal buildings that can be built in national parks are up to octagonal, and round buildings are not allowed. The reason why it is octagonal is that there is an octagonal hall in the temple, which is one of the buildings that can be built in the national park unconditionally. When we built Aso Farm Village, we had five experts gather in Kumamoto Prefecture. After explaining that it would damage the landscape, they were convinced and allowed the construction to take place. This time it didn't work. So, this time, I decided to make the rectangular pointy roof and walls of the cottage out of Styrofoam. to be continued
However, we did not have time to obtain certification for the Styrofoam structure this time. And the minimum frame is made of wood. At that time, plans were underway to build a cottage village in Shargarjut, a hot spring area in Mongolia. I was preparing to manufacture styrofoam parts in Beijing, China, which is located between Mongolia and Japan, so it was decided that the parts for this square cottage would also be made in China. We thought we had prepared enough, but unexpectedly, it turned out to be a very difficult time to produce parts in Beijing. I chose the virgin forest of beech on the site. As much as possible, we left the beech trees uncut and arranged the cottages. There is no straight sidewalk at all because the sidewalk is built around the beech trees. Since the roots of the trees are stretched vertically and horizontally, it is not possible to carry out construction work, and the slope of the sidewalk remains the same as the original topography.
