Making everything with woods.
Using woods as possible as we can. Local resources are Todo matsu and Kramatsu. Using local resource is good to reduce a wood milage. We think to use Smimokawa woods and propose 100& usage of the FSC authenticated woods. Also we would use Wood fiber insulation that has bee used in Shimokawa already. For windows, high airtight wooden frames with tripe glass and Low-E glass will be chosen.
