An important milestone has been reached with the laying of the foundation stone at Alter Wall 40 for what is currently the largest construction project in Hamburg's city centre. The reorganisation of the former postal giro office and later Sofitel is based on the compact historical development with individual buildings and courtyards lined up on the street and street side. The existing tower block will be integrated into the new concept and will also be used as a hotel in the future. A glass crown with restaurant, sky bar and terrace will create a new Hamburg highlight with the best view of the Alster and Elbe. There are also two modern office blocks and a residential building with 84 flats. Shops and restaurants on the ground floors will turn Alter Wall back into an attractive promenade, as it once was.
