Architects often talk about integrating outdoor spaces with the inside, but rarely do they succeed to the degree that Kazuyasu Kochi has here. In this small house the boundary between inside and outside is blurred by walls of glass bordering on covered and sheltered outdoor spaces. The actual interior space is a simple two-storey rectangular box with one-storey extensions at either end. Kochi covered this inner house with an over-sized tent of roof and bounding walls that extend beyond the inner house to define outdoor rooms at the front and back. The name of the house supposedly refers to the proportions of indoor space and protected outdoor space.
