A site with southern road has more value than a site with northern road. It is the typical small-scale development in Japan. The sites of both sides of the street face each other because of the rigid division rules.This house aimed to ensure openness and privacy at the same time even in that circumstance.

The Clients requested three outer spaces: parking, a courtyard, and a hidden drying laundry space from the street. V-shaped plan was satisfied them simultaneously as the simplest form. V-shaped house does not face with neighbors, the common spaces are in the west side, and the private spaces are in the east side. The fins as structure are lined on the both side of the courtyard. By these fins, the interior space is difficult to see from the street, but family has sight between common space and private space through the courtyard the east-west direction.
