Landscape architecture can be more than aesthetically innovative: It can contribute to integration in society, social stability and a vibrant public life. But how does a park become an intensively used stage, a well-visited everyday location? What constitutes the "boon of life" (Jane Jacobs)? And what makes a park urban?

The Park am Gleisdreieck in Berlin was initiated by citizens and built in dialogue with them between 2007 and 2014. Overall, this work lays out the design elements that model a sucessful citizens' park in the twenty-first century: Many voices have contributed to its development; its design is dynamically complex and the park invites change and appropriation.
