At its narrowest point, an average sized adult could reach out and touch both walls, but House K, a micro-home in Japan, houses two families.
The home may only be seven feet wide, but it is 30 feet high and holds 1,700 feet of living space. Still, with such narrow quarters it’s hard to believe two families could live in the home comfortably.
However, the house is divided into two uneven halves which contain enough room for two families, complete with kitchens, bathrooms, closets and a small kitchen.
And here’s a kicker: there’s no wall dividing the duplex. InHabitat notes that “this space-efficient house could act as a prototype for cooperative living arrangements that build community without sacrificing privacy.”
