A new living room is added to a cottage at the foot of Yatsugatake. On the gable side of the existing villa which has a sloped roof, a rafter with the same slope is installed and forms a gabled roof, harmonizing with the existing cottage. The shelves in the addition serve as the structure that supports the rafters, and the exterior sheathing acts as lateral bracing. Random glass inserts in the shelves brings light through the wall. In contrast to the existing part of the cottage, the extension is an open space that can be fully opened so that the surrounding nature can be seena nd experienced.
