The association's purpose is to offer children spaces that are removed from everyday life and free from performance pressure. The association creates a low-threshold space offer that is not subject to any consumption obligation and can be used free of charge. (Institutions that use the offer outside of opening hours pay a contribution to costs.) The space offer is intended to promote the free development and independence of children. The association serves the common good and is not profit-oriented. The association operates an indoor playground for children aged 5-14 in the Aktienmühle Basel. The association occupies the attic of the gatehouse located on the street side and acts as a contractual partner to the landowner, the Stiftung Habitat foundation.
