The existing apartment building at Hildebrandgasse 10 is being expanded by an attic conversion. As part of the additional storey, a new elevator will be built in the inner courtyard.
The existing buildings in the inner courtyard will be converted into two offices, and the existing apartments on the standard floors will be refurbished and brought up to current standards. In future, the energy supply will be provided by a modern air-source heat pump in combination with a photovoltaic system.
