Katharinen District

Modern and well thought-out metropolitan quarter between Hamburg's city centre, Speicherstadt and Nikolaifleet

In the heart of Hamburg's old town, a new residential and commercial quarter has been created with around 130 apartments, small-scale commercial units, and an office and business complex. The planners of the Katharinen District have successfully balanced the creation of new urban living spaces with the preservation of existing urban structures.
