The TaunusTurm tower was the first building on the Neue Mainzer Straße. Its 13 m high entrance lobby faces the adjoining park. The lower six floors of the skyscraper are shared with the adjoining Wallanlage residential tower, and simultaneously form a solid basis for the high-rise building above them. The base building with its protrusions and recesses provides a nuanced form of integration into the neighbouring park and street area. Besides the public lobbies, it houses a canteen, generous office space and the technology floor.
