For the opening of B-Part in March 2019, a temporary co-working space at Gleisdreieck, we developed an explanatory film that presents one of the largest current building projects in Berlin, the Urbane Mitte am Gleisdreieck. Particular attention was paid to addressing all interest groups from the public, politics and business, and generating enthusiasm for the project. The film was presented by Berlin’s Senator for Building Development, Katrin Lompscher.
