A new multi-user sports facility at the listed school building, Søndermarkskolen, Frederiksberg Kommune, has been selected by Lokale- og Anlægsfonden, DIF and Dansk Skole-Idræt as one of five projects to be carried out. The project transforms a traditional ”gymnastiksal” into a shared social space and everyday lab connecting school, sports clubs and local community. The purpose is to daily facilitate more physical and mental health promoting activities. Through co-creation between key stakeholders, users and the studio novel ideas combining architectural and organisational strategies have merged into an innovative common project to be further developed throughout 2021.
