Karuizawa, Japan, Shell House

If one were flying over Karuizawa, Japan, and saw the roof of the Shell House, it’s possible that one could entirely miss the fact that it’s a house. The dwelling was created by the Japanese architecture firm ARTechnic, and its unusual exterior design resembles nothing so much as a cannoli transforming into a spaceship.

Described as “out of this world” on the website Trendir , the structure’s curves and ellipses give it a look like nothing before or since. It has sound design principles behind it, however, and takes advantage of natural light and interior textures, so you can feel at home once you’re actually inside of it.
