Horinouchi House in Tokyo, Japan, a very modestly sized (56 m³) house that makes the most of its tiny footprint, designed by Mizuishi Architect Atelier. To wit:
Slightly reminiscent of a submarine’s periscope, the Horinouchi House’s triangular-shaped exterior allows it to fit snugly into its modest plot of land. Inside, the home is spacious and incredibly well lit, succeeding in making it feel much larger than it actually is. Its lower level houses a master bedroom and bathroom, along with a kitchen and dining room, while the upstairs quarters are primarily reserved for communal activities — think a den or living room.
