Call a shoebox home? Trust me, you're doing awesomely compared to the poor sap who'll eventually reside in this 133cm-wide "house" in Warsaw, Poland. Designed by architect Jakub Szczęsny, "Keret House", as it's called, measures a meagre 14.5m², barely enough living space for, well, a person, let alone furniture.
According to CNET, it'll draw power from adjacent buildings and a "boat-inspired water and sewage system" will take care of hygiene demands. The stairs also "flatten" to provide easier access to the outside world.
I'm no structural engineer, but wouldn't it have been better as a rectangle, rather than a triangle? Sure, it looks sleeker with three sides, but there's all that wasted space.
The building is still under construction, with completion planned sometime next month. A couple of extra shots can be found below.
