Located on a generous site in Nakatsu, Oita Prefecture, this single-story house is separated from the street by a wooden slatted screen. It’s reminiscent of fortified towns from Edo period. The concrete roof of the 211.3 m2 (2,274 ft2) home is swept upward on four rectangular boxes. They contain the entrance, kitchen, bathroom, and storage. The house is naturally lit by daylight entering through a skylight in the top of the roof.
