Hafenspitze, Hyatt-Hotel
The structure which is around 55 metres high with uninterrupted glazing consists of two towers. In order to express the different functions on the exterior, the two more or less identically designed buildings cantilever sixteen metres in opposing directions from the sixth storey upwards. The form which is based on old harbour cranes is not only a striking architectural climax to the building project on the narrow peninsula, it also echoes the industrial history of the area. The tower which faces north-west provides office space on 17 floors. The other tower contains the Hyatt Regency Hotel which has more than 300 rooms and faces south-east to the old town and commercial harbour.
