The purpose is to promote, create and procure affordable housing in rental and ownership relationships on a non-profit basis in the sense of the Federal Housing and Property Promotion Act (WEG). The activity of the cooperative is not profit-driven. In particular, it aims to promote forms of housing that optimally meet the interests of the residents, namely in terms of legal status, co-determination, mixed use, architecture and comfort. The cooperative takes into account, as far as possible, in the sense of integrated housing, persons, families and groups with special difficulties on the housing market. Ecological aspects are appropriately taken into account in site selection, construction and maintenance. The cooperative creates and rents affordable housing and houses primarily to its members. Sale is not excluded. It can acquire, encumber and sell land for this purpose. When selling real estate and houses, the cooperative ensures that buyers cannot engage in speculative transactions. To this end, the cooperative can reserve pre-emption, purchase and co-determination rights. The houses and apartments owned by the cooperative are to be permanently withdrawn from speculation and used in the sense of affordable housing. Self-managed and communal forms of housing are to be realized as far as possible; can participate in companies with the same or similar objectives.
