Located in the Ibaraki Prefecture, Japan, this house with a large hipped roof is a project completed by Naoi Architecture & Design Office in 2013. This is a house for a family of four, situated on one of the lots for sale at a newly developed area in “satoyama” or semi-natural woodlands. The land is too large for a simple program requested by the client: a private house with a garage for two cars. The house consists of an open square plan intersected by living room in the middle, and master bedroom, bathroom, dining/kitchen and closet are located along both outer zones. The living room space extends horizontally via the “engawa” (or veranda-like intermediate space located between the interior and the exterior) towards outside. The living space, which can be freely subdivided as necessary by sliding doors, provides both an appropriate degree of privacy and a feeling of togetherness simultaneously as same as traditional Japanese houses.
