For mixing refugees with the increasingly diverse population structure in cities, PRINCIPLE PLURAL offers a solution that is both sustainable and cost-effective and can be implemented quickly. PRINCIPLE PLURAL makes integrated housing attractive for all people in the city. It combines the advantages of private living with life in a larger community. Withdrawal into the private sphere is just as possible as contact with the community. This is achieved through clustered private living modules, which, in addition to bedrooms, have their own bathroom with shower and a small kitchenette, and a lively community zone that surrounds the living modules and holds them together. Differently dimensioned and organized living modules meet different needs. PRINCIPLE PLURAL is also attractive for „temporary living“, for commuters, project-based employees, students, etc. The living modules open to one side and can therefore be flexibly lined up. The merging of the living spaces into a common zone leads to a reduction of the individual living space requirement to less than 33m2, despite additional offers. All living areas are barrier-free.
