The Next Generation House by Sou Fujimoto Architects looks  like a house built with Jenga blocks. The NGH is a small weekend house that overlooks the River Kuma in Kumakura, Japan. It's approximately a 13'x13'x13' cube, but  functional enough due to the ramshackle space that is formed by the cedar logs, creating spaces for seating, sleeping, eating, storage, etc.
