Slideshow: overlapping openings in the walls and ceilings of this Tokyo house by Japanese architects Suppose Design Office create dozens of views between rooms.

Contained within a rectangular wooden volume, the family house accommodates rooms for living and sleeping on its two main floors, plus an open-plan loft accessed by ladders.

Some rooms on the ground floor are set at a lower level than the corridors, while the attic storage areas are raised up slightly higher than the surrounding floor.

Narrow handrails screen balconies on the upper two floors, so residents have to be careful not to slip over the edges.

Other popular houses by Suppose Design Office include one where interior walls don't touch the floor - see more projects by the architects here.
