U5-Haltestelle Hauptbahnhof Nord

The U5 Hauptbahnhof Nord station in Hamburg is being carefully developed within the listed fabric of the existing station. The principle of precise reduction and addition preserves defining elements of post-war architecture and makes the original spatial qualities tangible again. Existing structures, materials and characteristic design elements are refurbished and complemented by a few durable interventions, retaining the embodied energy of the building. The four historic tunnel tubes are reinterpreted as a continuous spatial sequence and transformed into a contemporary, distinctive station for the U5.
