Yes, someone actually built an entire home atop a single parking space. Fuyuhito Moriya, 39, “purchased his 30 square meter plot of land in Tokyo — it was advertised as a spot to park a car” — and turned it into a home for $500,000. Video after the break.
The spiral staircase that connects the three floors – Moriya couldn’t build horizontally, so he built vertically – is triangular instead of circular, allowing for a tighter diameter. Sinks look like they were cut in half.
