Architecture

The complex consists of three high-rise blocks, some of which are arranged within the interior of the city block. Two elongated buildings frame the ensemble facing Hohenzollernring and Friesenwall. Foster wove nature into the modern design: tucked inside lies a lake alongside an area of trees and shrubs. These spaces are not open to the public and remain the exclusive preserve of residents.

Construction and History

The building was constructed by Hochtief at a cost of around 24 million euros and inaugurated in October 2001. During excavation works, archaeological artefacts came to light and were incorporated into the underground car park.
