House H / Yoshimasa Kishimoto Architects Studio

A grid of four-and-a-half tatami mats was adopted as the unit for constructing the dwelling. The composition is based on the rule of arranging and dividing the area along this grid. This is an extension of the composition system of Japanese minka houses, which used to be called nimadori (two rooms) and mimadori (three rooms). It is a flexible form that can be arranged with simple rules, can be used as a small or large space, and can accommodate a variety of functions. 4.5 Tatami Mat Grid can be connected in any number of ways and in any direction, and the outer shell was designed to be free. Based on this premise, the site conditions and the client's requests were incorporated to create the overall vision of the house.
