HafenCity – HC34

The perimeter block development of construction site HC34 of the HafenCity urban development project was planned by the architectural firm Blauraum in cooperation with Nalbach Architekten. Werner Sobek was responsible for the structural design of the project. The two buildings are connected by a two-storey underground structure. Above ground, they are separated by an alley.

Diverse Building Use – Detailed Optimisation of the Structural Systems

In addition to flats, the building houses shops, a cinema and a parking garage. For the diverse use of the building, a detailed optimisation of the different load-bearing systems was necessary. In this way, the most economical load transfer possible could be realised down to the foundation, which rests on partial displacement drilled piles. This ensures load-free bridging of the crossing district heating tunnels.

Another challenge was the arrangement of the cinema halls below the hotel rooms. The solution here was a room-within-a-room construction, through which both areas of use could be completely decoupled from each other in terms of sound.
