House in the Forest

Project: House in the Forest
Location: Yamanashi, Japan
Project category: New build Residential
Stage: Completed

Appearance, construction and perfomance should go hand in hand. This forest retreat was designed to maintain a cool indoor temperature during the hot Japanese summers.

Only an hour and a half from their home in Tokyo, this red cottage provides a retreat for the owners from their urban city life. An escape from the city is good for the body and soul, especially during the hot and humid summer.

Situated in the presence of Mount Fuji and close to the scenic Sai Lake, this cottage blends images of Scandinavian cottages with a roof geometry that nods to traditional Japanese shrine architecture.

The whole building is designed around the size of the tatami mat, a rectangle measuring approximately 90 x 180 cm. This informs the grid of the layout and every elements is a multiple of this size to ensure efficiency in material use.

A dramatic interior is created by the tall roof, which is supported internally by a tree-like column made from local timber. As hot air rises, it is expelled in vents on either side of the clerestory window, creating a stack effect that in turn draws in air from the cool surrounding forest floor.
