experimentcity was initiated in 2003 by id22: Institute for Creative Sustainability, emphasizing the development of a diversity of cooperative, environmental and affordable housing forms as an essential contribution to a culture of sustainable urban development.

experimentcity, through a networking of experts and activists, artists and creatives as well as researchers, administrators and business people – supports innovative urban and community development strategies – transforming rigid top-down approaches into democratic and participatory processes.

With project exhibitions (EXPERIMENTDAYS), Internet databases (WOHNPORTAL), publications and various events such as workshops, study visits (Creative Sustainability Tours), exhibitions or Wohnsalons, experimentcity communicates the potential of a culture of creative and participatory sustainable urban development.

Since 2010, experimentcity europe networks co-housing activists and experts at the European level supporting the exchange and transfer of locally-based experiences and knowledge.
