The prestigious Neo-Renaissance building Bei St. Annen 1 dating from 1904 opulently stands out as the "town hall of the Speicherstadt" from the surrounding, modest warehouses with its light-red faced brickwork, the decorative divisions from sandstone as well as the ornamented gables and turrets.
For several years the neighbouring warehouses Holländischer Brook 4, 5 and 6 were used as a necessary extension for office uses. Inadequate builtin units, ineffective internal circulation and the wish of the HHLA, to set an ideal example for a conversion in the Speicherstadt, which is under a preservation order, were reasons for a synthesis of different historic buildings and architectural styles. The connecting central space between the administration building and the warehouse is the former inner court, now transformed into a hall as high as a house. Finished with a glass roof and equipped with a glazed lift, it is a polystylistic synthesis of all existing eclectic elements of style and existing materials, such as the timber skeletons of the warehouses, glazed brickwork, slate, copper, polished granite columns, terracotta tiles, cast iron columns, and stucco of the Speicherstadt town hall.
Due to low ceilings and insufficient daylight the warehouse floors were not suitable for office use. The new double-corridor-plan allows single cell offices on both sides of the building. Glass partition walls with fine steel sections and light suspended floorbays between the existing wooden load-bearing structures generate a brighter and wider appearance of the offices. In the interior the ceilings were removed to allow for visual and also communicative links between the single warehouse floors. Open stairs shorten the internal distances. The variety of the architectural layout has a stimulating effect for the HHLA staff in the converted ensemble.
