The property at 28/30 Spittastrasse is located in Berlin-Lichtenberg. This project involved the rehabilitation of a residential complex in Viktoriastadt. As part of the comprehensive modernization and restoration, the attic space was converted and balconies were added on the garden side of the building. The building also includes maisonette apartments with their own yards and terraces. Through the installation of a solar-energy system, attention was paid to environmental aspects as well as costs.
