I've always been amazed by modern, minimalist architecture but this, is just epic. A description of this house:
Takei-Nabeshima-Architects (TNA) architects have designed a striking mini-tower on spec for a planned community in the town of Karuizawa, some 185 miles northwest of the Japanese capital. The Ring House is wrapped in rings of glass and wood and has an uninterrupted 360-degree view of the forest.
