PARK haus

Transforming Züblin Parkhaus in Stuttgart

From parking lot to community centre

In order to reduce the number of cars in the city centre of Stuttgart, the highway B12 is to be narrowed from a four-lane street to a two-lane street. Nearby, a mobility hub is planned right next to the Züblin Parkhaus, the project's location. With the Kultur Kiosk inside this multistorey car park, it is already used as a cultural spot with exhibitions and different events on the rooftop. The new plans for Stuttgart's city centre leave the Züblin Parkhaus unused and in danger of demolition. To save CO2 emissions and to prevent the surrounding greenery from being destroyed, the concept of the conversion is to provide new value to the plot by combining nature, culture, working and communal housing in one building. For privacy reasons, the utilizations are separated into "public" and "private", each located on one of the two ramps, that form the characteristic structure of the existing building.

Using the open space for public, semi-public and private utilizations

Natural ventilation through the atriums and evaporative cooling through facade greening prevent the building from overheating during the summer. During the winter, the atriums serve as a buffer zone that heats the adjacent infills, thereby reducing the building's overall energy demand. Furthermore, collecting and filtering rainwater on the roof reduces the need for external water supply.

Climate concept

With its existing green and further greening of the roof and the facade the PARK haus serves as a cool spot in a heat-stressed area, making it the new centre of the two adjacent residential districts. The plants not only improve the microclimate with evaporative cooling, but also support biodiversity.
