The second Berlin city centre proposal revealed today is a cluster of five towers by Graft and Kleihues + Kleihues Architekten, which will be connected on their upper levels by a chain of bridges.

Named Eckwerk, the mixed-use development will be located beside the railway viaduct in Berlin's Holzmarkt area. It will contain a series of flexible units that can be used as homes or workplaces, as well as a large public atrium conceived as a "multi-storey marketplace".
