The 162 m tower together with the 112 m "Langer Eugen" by Egon Eiermann and the low-rise Deutsche Welle by Joachim Schürmann form the edge of the city to the Rheinauenpark. The tower's platform completes the upper terrace of the park connected by grand ramps and stairs to the lower terrace near the Rhine. The split, shifted oval is oriented to the Rhine, Siebengebierge and the city, facilitates views from the city, and minimizes negative wind effects through its aerodynamic shape.The building rethinks the type of high-rise office tower in relation to function, technology and user comfort. In plan the split oval halves are separated by a 7,20 m wide space. The connecting glass floors at 9-story intervals form skygardens, which serve as communication floors and elevator crossovers. The glass elevators of the low and high zones run in the center of the skygarden, providing views and orientation.
