This incredible linear house design in Okinawa is by Japanese architecture firm Shinichi Ogawa & Associates. Long and lean, this linear house is simple through and through. Its exterior features four white rectangular concrete slabs, plus one for the roof, while inside is much of the same with some functional features built in. The rooms’ unique “hallway” dimensions really demanded a scaled-down decor – only the essentials, an approach that worked in favor of the minimalism aesthetic. Floor-to-ceiling glass walls enclose the main living and dining area and bedroom, while the kitchen, study room and powder room enjoy full enclosure. Shinichi Ogawa & Associates
