on a pentagonal site in kumamoto, japan, the ‘diamond’ house by local architect hiroyuki arima seeks to benefit from as much of the footprint as possible while leaving room for exterior space and trees. the plan is divided into zones, volumetric projections onto various areas of the plot connected by a large central volume that mimics the boundary line of the site. square windows of different sizes are strategically located to accept daylight into the various programmatic elements and extend views. the ground floor contains the social spaces, kitchen, living room, storage and two additional multi-functional spaces. a set of stairs located in the double-height living area leads to the private upstairs that contains three bedrooms and a stage. the walls and roof are all stark white, interior and exterior, given color with the natural wood flooring.
