At the BMW Group’s Munich site, the historic multi-storey parking lot is a defining feature of the urban landscape. Because it was getting on in years, a consortium consisting of SAA Schweger Architekten and pbr Planungsbüro Rohling AG renovated it. The renovation work has now been completed and the parking garage is fully operational.
Between 1969 and 1971, architect Karl Schwanzer built the concrete parking garage used by BMW Group employees. It is a testimony to the building culture and part of the ensemble of BMW Group plants in Munich, consisting of the striking administration building – the so-called four-cylinder – and the museum. The seven-storey parking garage is a listed building. However, the supporting structure was so badly damaged that the building could only be dismantled. In order to preserve the appearance of the existing building, large parts of the historic façade made of prefabricated concrete elements had to be retained and secured in situ. In addition, fire protection regulations for natural ventilation made it necessary to move the existing façade away from the parking garage. The renovation of the building was carried out according to the house-in-house concept. According to this solution, the south façade and parts of the east and west façades were retained as an external façade of the building after extensive refurbishment, as required. The parking garage itself was completely rebuilt with a new composite steel structure.
Separate façade
A joint to the existing façade creates the required ventilation area. The new multi-storey building with a total of 1,600 parking spaces was constructed using split-level construction. Because the new building is higher than the existing one, its façade protrudes beyond the listed exterior wall of the existing building. The additional storey and the north, east and west façades were set apart from the existing building with a curved perforated sheet metal construction. An elaborate temporary steel structure had to be erected before the façade was separated by saw-cutting. This steel scaffolding supported the free-standing façade elements. The remaining façade was dismantled and reused as a replacement on the south and west façades. A steel structure independent of the parking garage supports the elaborately renovated façade panels made of prefabricated elements.
With the redesign of the parking garage, the opportunity was also taken to implement contemporary requirements for parking spaces and traffic routing. This was achieved not only with the help of a parking guidance system, but also with wide parking spaces and vehicle aisles that take into account the vehicle dimensions common today. Presence-controlled LED lighting adapts to the brightness, and the modern version of the charging systems for electric cars was also implemented.
