The design by Ferdinand Heide envisages the construction of a 288-meter office and hotel tower (Tower A), a 157-meter residential tower (Tower B) and a block perimeter building in a wood hybrid construction. In terms of building law, the two high-rise buildings have a height of 280 meters (Tower A) and 150 meters (Tower B), which are, however, slightly higher due to the two sloping roofs. The two towers will be twisted in an intriguing way creating spacious terraces and attrac-tive projections and recesses in the building cubature, especially in Tower A. Through the “twist” in the towers, however, the design also succeeds in increasing the distances between the buildings, which is particularly beneficial for the lighting of the flats in Tower B and significantly increases the energy yield for photovoltaic systems integrated into the façade. On the ground floors, the design provides for public spaces with a high quality of stay.
The crowning glory of Tower A is the design of a publicly accessible “Sky Hall”, which can be used both as an event space and as a viewing platform.
