An extremely narrow apartment showing that "unnecessary" space in cities can be used for living

Detailed Description:
14 square meters - It’s an extremely tight fit to say the least. Yet it squeezes in a bathroom, kitchen, and a reasonable place to sleep, in the crack between two other buildings.

Region of use:


The building measures 92 centimetres (3.02 ft) at its narrowest point and 152 centimetres (4.99 ft) at its widest point. The iron structure contains two floors, and has one bedroom, a kitchen, and a bathroom. It has no windows that open, sunlight only entering through a screen of small holes in the bedroom walls. The entire interior is painted white, and the building's electricity is obtained from a neighboring building. The house has custom water and sewage technology, and is not connected to the city-provided water systems. Because of its small size, the building only accommodates a small 2-beverage refrigerator, and occupants use a ladder to travel from level to level.

By demonstrating that there is no such thing as an unnecessary space in our growing cities, the architect took advantage of this left out hole between two buildings. Nothing "useful" could be put in this space, not even 2 m wide - yet the two buildings were high and the total area of unused space was quite significant. This house (which in Polish regulation is counted as an art installation due to to its size) aims to show that there are architectural solutions to every environment, and that a lot of space that we find useless actually can be turned into a house, an office or perhaps something completely different!

Shortage of housing is an issue in nearly every larger city. Students and low-income individual have tremendous problems to find affordable (if yet ANY) housing. The cities can't keep expanding horizontally forever, so innovative solutions and perhaps a new definition of what a "house" is are needed.
