Anne-Sophie Free School Berlin is a tenant in the premises of the "Zehlendorfer Welle" building complex in Berlin. On the roof area above the second floor of an existing two-storey building, the school has now been given a 10 m high two-court sports hall and a schoolyard. When it is dark, the light inside the gymnasium penetrates through the translucent polycarbonate façade to the outside, transforming the building into an unusual cubic body of light.

The largest surface area of the façade is formed by a single-skin system of translucent multi-chamber multiwall polycarbonate sheets. As a hollow chamber element, the façade cladding achieves a glazing U-value of up to 0.8 W/(m²K) and an overall energy transmittance of up to 27 %. With the correspondingly good thermal insulation properties, the requirements of the 2009 Energy Saving Ordinance were met in the verification calculation for the almost "fully glazed" structure. The room acoustics requirements in accordance with the use as a school sports hall could be implemented using a sound-absorbing perforated trapezoidal sheet metal ceiling, among other things.
