The Blissestrasse 5 project is an example of a contemporary, sustainable approach and a conscious examination of the existing architecture from the 1970s that characterises the city in this neighbourhood.

Built in 1971, the former Berlin-Wilmersdorf tax office covers around three quarters of the block Blissestrasse 5 / Berliner Strasse 132 / Uhlandstrasse 97 / Wilhelmsaue 26-27. The ground floor is almost completely built over and is mainly used for retail and parking purposes.

As part of the extensive refurbishment of the nine-storey office building complex, the office floors of initially two of the four building sections were converted, equipped with a pressure-ventilated stairwell and a fire brigade lift, the building services were modernised across the board and the underground car park was sealed by installing a new, partially lowered floor slab.

The new, rear-ventilated, curtain façade consists of large-format, highly weather-resistant, powder-coated, white aluminium sheet cassettes. These are structured by widely projecting window reveal boxes made individually from extruded aluminium profiles. The single-storey façade of the car park facing Wilhelmsaue was clad with pre-faced aluminium louvres.

The complex was also given an appropriate, prestigious entrance.
