On July 1, 2025, the Treptow-Köpenick district office celebrated the topping-out ceremony for the construction of a new three-field sports hall at Walchenseestrasse 51.

The ambitious goal is to increase the school places from currently 810 to up to 1,132 places, which takes into account the demand for school institutions in a growing district. The construction of the sports hall represents the second construction phase that is necessary to meet the increased need for sports areas.
