This report summarizes the results of all four trialoge of the series "Participation in Housing". The description of the urban conflicts as well as the analysis of the current participation practice in Berlin are followed by an outline of necessary framework conditions for participation in housing construction and concrete proposals for the design of informal participation in housing construction. On this basis, guidelines for participation were formulated for the state-owned housing associations. After their public presentation, the guidelines will be tested and evaluated in a one-year pilot phase.
