The Bolwoningen Ball Houses
The “Bolwoningen” project by architect Dris Kreikampa was chosen as an experiment in affordable housing by the Netherlands government and construction began in 1980. Bolwoningen consists of 50 spherical houses made of cement, reinforced with fiberglass. Each sphere’s diameter is 18 feet and each has 11 round windows. Weighing just 2755 lbs, the house can be completely disassembled and transported to a different location.
