The GSP eG, or Genossenschaft selbstverwalteter Projekte, is a cooperative based in Berlin, Germany, that focuses on sustainable and socially responsible projects. Founded on the principles of ecological sustainability, social justice, and democratic economy, GSP eG aims to create innovative and inclusive spaces for living and working.

One of the cooperative's notable projects is the development of 197 apartments, a kindergarten, and community spaces in Berlin-Karlshorst, scheduled for completion by 2027. This project not only provides affordable housing but also incorporates shared spaces such as a community kitchen, café, workshop, garden, and rooftop terrace, fostering a sense of community among residents.

GSP eG also engages in the revitalization of historic buildings, such as the former "Konsumverein Vorwärts" ensemble, which is being carefully modernized and expanded. The cooperative's commitment to environmental sustainability is evident in its focus on renewable energy sources and circular economy practices.

In recognition of its efforts, GSP eG was awarded as Berlin's most social enterprise in 2022 in the category "Mensch" (Human). This award underscores the cooperative's dedication to creating projects that are not only environmentally friendly but also socially inclusive and economically viable. Through its work, GSP eG contributes to the growing movement of self-managed communities and businesses in urban and rural areas.
