A single prominent city-owned building occupies the triangular lot at a central location in Zurich’s district 4. According to applicable zoning regulations the allowed building height is substantially higher than the current building. This potential has been studied in a commission by the client and discussed with the relevant authorities. The City Council and Department for the Preservation of Historical Monuments are open to the vertical extension, but the clients want to wait for a neighboring large-scale project in light of a potential shortage of parking spaces before continuing with the project.
