The „Haus des Lehrers", built in 1963, was the first skyscraper at the Alexanderplatz. It was an important symbolic building in the former GDR. „Memorials for a new society" deals with the town planning in the new capital Berlin. The work reflects these plannings and tells about the Potsdamer Platz, the reconstruction of the town castle and many more buildings. Many decisions of these plannings are politically motivated. In a fictitious competition the momentary plannings are uncertained and different utopian proposals are developed.
