Nele Trautwein of GenerationenWohnen:
There are two types of co-housing:
1⃣Housing communities, where each person has private apartments and co-living spaces.

2⃣Cluster apartments, which are private mini apartments with co-living spaces such as living rooms.

One way to create co-housing is by renting to housing companies.
Therefore, a housing company willing to integrate groups is needed.
Berlin has six municipal housing companies.
