Within the glassed-in area facing the Friedrichstrasse, a thin rod of light (height: 21 m) was installed at a slightly tilted angle. Through its multiple reflections on the surrounding glass, a separate lighted space is created.

We designed a solar reflecting system for the narrow lighted courtyard (5 x 5 m) in the residential building in the Friedrich-Carré. The rays of sun are reflected all the way down to the bottom of the courtyard. The mirrors are set at steep angles and provide for minimal shadowing of the direct incident light.
