“Wooden cave” is the concept. The unique space with trees enables visitors to sense the rich forest resources that the community had cultivated. Like a cave, the structure invites people deep inside while walls create separation. Various places can be glimpsed and connected. The network of inhomogeneous scenes weakens the abstractness and geometrization of architecture and brings forward the depth and expectation. The construction material of the wall column is a commonly distributed heartwood Japanese cedar, 4 meters in length, 120 x 180 millimeters (partially 210 millimeters) in cross-section. Considering the actual workability as well as the drying shrinkage, the triangular surface was segmented to a 600 millimeter unit and combined with hardwood dowels and spline joints rather than adhering.
