Alien neighborhood of Bolvoningen in the Netherlands
Unusual houses-spheres were built back in the 80s according to the design of local architect Dries Kreikamp, who won a competition for affordable social housing projects. One of their features is the modular construction, thanks to which everything can be quickly dismantled and moved to another place, assembled in a day (but in the end, no one did so).
The area of each of the 50 houses is 55 m², and inside is the same three-level layout with a small pantry, bedroom, bathroom and kitchen-living room. And yes, there are real people living in them
