“Walden 7” – This very unconventional building was designed by Ricardo Bofill. This was his attempt at what a social housing utopia would look like. The building is based off of B.F. Skinner’s science fiction novel, Walden Two, which depicts a utopian community. The building itself is actually made up of 18 different towers, collectively containing 446 rooms. Bofill attempted to tackle housing and spacing issues, with shops, pools and bars all being made part of the housing.
