Fuyuhito Moriya, 39, lives with his mother in a custom-built home set on a lot that's only 30 square meters. It used to be a parking space. Moriya spent $500,000 constructing a compact three-story house on the site:
South-facing, large windows create the illusion of space. Minimal furniture and clutter keep the small home tidy. Hideaway cabinets for kitchen appliances and half size sinks shrink expected space.
Even the spiral staircase shaves inches, drawn as a triangle instead of a circle, slashing the space's diameter. The corners of the staircase become small closets, to stash shoes.
"Every single corner is used," says Moriya.
