Skewed from the grid of kitakyushu in the fukuoka prefecture of japan, the 'kokura tanaka house' was discovered by our friends at JA+U and is designed by tokyo-based practice tanaka akinari kenchiku design office. positioned upon a square plot bound by detached houses, the a single-storey structure makes the most of its tight site by rotating the dwelling on an axis to form four triangular gardens around the periphery. the perimeter enclosure is a combination of wood partitions to offer surfaces for storage and sliding glass doors which open to the outdoor courtyards with green areas and dry gardens.
The triangle motif is continued inside by criss-crossing the home with two load-bearing concrete block walls. spanning between the home's four corners, the living spaces are placed within resulting triangulated quadrants.  primary spaces include a living room, dining area + kitchen, bedroom and a bathroom with storage. inhabitants may climb between a lofted floor and built-in ladder to reach a skylight and access the roof.
