The architectural concept consists of two 35-storey high curved towers that are connected to form a core to the south-east of the Grossmarkthalle. The towers create a vertical counterpoint to the horizontal plane of the Grossmarkthalle. The curved towers open out towards the entrance drive and the river, maximising the views both to and from the towers. The Grossmarkthalle is preserved and remains fully visible from the Sonnemannstrasse. The design concept of the second phase differed significantly from the outline concept of the first phase, which consisted of two parallel slabs cantilevered above the Grossmarkthalle to unite the Grossmarkthalle and the river without destroying the autonomy of this historic building.
