This 7- and 8-storey perimeter block project is part of Hamburg’s urban development “HafenCity”. It was built on plots 34/15 and 34/16. Both plots are connected by two joint basement floors. Above ground they are separated structurally by an alleyway. Due to the varied types of usage to be found in the buildings (residential, hotel, retail, cinema, and parking), the different load-bearing systems had to be finely coordinated in order to achieve the most economical load transfer to the foundations. The foundation itself was carried out on partial displacement piles. This ensures a load-free bridging of the crossing district heating tunnels. Another special feature was the arrangement of the cinema halls below the hotel rooms. The systems were completely decoupled from each other by a room-in-room construction.
