MVRDV Architects created this small project called the Didden Village in 2006 in Rotterdam, Netherlands. It was created for the purpose of giving a residential area for local people. It is very small, only 120 m^2. It is on a rooftop of a historical building and atelier. There are multiple bedrooms for each person in order to keep privacy.
