The Biosorber project is intended to combine living and working. Close to the highway, this building includes a drive-through workshop. Cars are led from the road to the middle level of the building, where they can be transported to the basement by a lifting platform. The shell of the building is designed as a tank that collects the dirty wastewater from the motorway and cleans it with integrated microfilters/algae so that it can be used in the household.
