Mobility within growing urban structures is changing rapidly. But although the concept of car-free city centres and the idea of a new green mobility are becoming more and more popular, there is one typology that is growing out of the ground in almost unchanged numbers and speed in the cities of Germany and the world: the multi-storey car park.

Like monuments of a car-dependent society, they are spread throughout the urban fabric of growing cities. The demand for parking spaces remains high and continues to pose challenges to urban planners and architects alike. But how do we deal with these structures if the ideas of a car-poor inner city, more space-saving mobility and more liveable public spaces come true in the future? One thing is foreseeable above all: the demand for living space and the need for privately and publicly usable areas in the large cities of the Federal Republic of Germany will continue to increase. The scarcity of land and ecological principles will increasingly cause cities to grow and densify within their existing boundaries. Structures that have outlived their function will have to be repurposed. What is already a reality in many former industrial districts that have long lost their economic significance could also threaten the previously largely uncontested territories of the automobile. However, many of the existing car park structures could then only change their former purpose at great expense. In many cases, demolition would become the standard economic solution. But the principles of sustainability demand other concepts.

The "postautomobil" project is concerned with the design of a multi-storey car park whose structural structure can survive its initial use and continue to be justified as an important element of urban development and will continue to be justified as an important element of urban development in a world after the automobile. As living space, working space, playground, bicycle park, greenhouse or social meeting place.
