The WinX Tower will be completed as the final segment of the MainTor ensemble. At a height of 110 meters, the WinX–The Riverside Tower is the highest of those in the MainTor quarter which stands directly on the banks of the Main River and interfaces the river, Old Town Frankfurt and the CBD. The office high-rise stands out from the other MainTor buildings for its materials and style. The 28-story tower is characterized by a reflective metallic skin and an unusual shape, as it rests on an x-shaped footprint. The striking entrance: the seven-story portal building on Neue Mainzer Strasse, which marks the beginning of the WinX Tower, combines classical architecture and sheer dynamism.
