Showroom is experimental room for the decentralised museum. This installation was a beginning of a series of artistic actions that are carried out in the summer of 2014. in Bernau. The idea was to create a collection of works that are exhibited in private homes. In this way, the project promotes the idea of decentralised museums. The artistic interventions are taking place in apartments in order to get to know individuals, their history and their daily lives better. By articulating everyday activity in artistic interventions the art collection is made, and the space of the apartment becomes similar to that of museums and galleries. The project is an exploration of social and cultural heritage. It examines the importance and handling of subjective social and cultural heritage in new ways. What remains as a cultural artefact and for whom?
