Delta House

Located in a rural suburb of Kanagawa, the Delta House has been conceived by Yoshiyasu Mizuno as a triangular building where rooms wrap around a central doma, the traditional Japanese family room.

Delta house is a small house in the residential neighborhood of Tsujido, Kanagawa.

The site is approximately one kilometer away from the ocean as well as from the comprise part of the area which was recently converted from agricultural land to residential use.

The plot is extremely irregular in shape as there was a formerly farm road crossing the property.

Total volume was roughly determined based on the shape of the plot, the Building Standards Law, but also the need for parking space. The project tries to enlarge the interior space of this small house and to explore the relationship between interior and exterior spaces. Those resulted in creation of a doma (a room which is partially outdoors and set approximately at ground level; in traditional Japanese homes, it combines the functions of kitchen and agricultural workshop) which creates the approach to the house combined together with an adjacent triangular atrium.

This has helped to create a sense of separation between rooms, increase spaciousness, and form a better connection with the outside neighborhood in a way that is impossible to express with standard metrics. As with Japanese houses from previous periods, this house enables its occupants to freely adjust private and public areas depending on the occasion.
