As part of the new construction plans, the 8,000 square meter Hugenottenplatz was redesigned and renovated, as was the five-story office building "Kubus" opposite.

[3] The design for the City Tower was created by the Offenbach-based architectural firm Novotny Mähner Assoziierte.

The main tenant in the City Tower was the management consultancy Capgemini until 2017, and since then it has been the tire manufacturer Falken Tyre Europe.

The quantity of windows to be opened in the main facade is increased to allow for optimal ventilation and to diminish artificial lighting.

In conjunction with the facade, cutting-edge energy and building technology promote low-energy and eco-friendly resource-efficient functioning.
