LERA was the structural engineer for this classic work by renowned architect I.M. Pei, consisting of a glass-and-steel addition to the German Historical Museum connected to the original museum building via an underground passageway.

The addition is composed of a glass-enclosed spiral staircase, a 16,100-sf glass wall and a 9,500-sf skylight. The design’s intent was to make the original opaque building more inviting to the public. With every step, new perspectives open up in both the light-flooded entrance hall and the traditional architecture of the surrounding city center, such as the neighboring baroque building, dubbed the ”Zeughaus,” which was once the old armoury.
