Starting in the 1970s, the former clay quarry served as a landfill, which is why the surface water is not permitted to seep in and has to be discharged on the surface. The slope of the pit has now been placed under nature protection.

We have created habitats that are as diverse as possible with large water retention and evaporation basins. Geometric shapes contrast with lush vegetation corresponding to the artificiality of the location. The water will erode the bank and the artificial clarity will give way to natural forms over the years. Our design thus makes the influence of time and the forces of nature visible without an artificially generated patina. Swisscom’s large building and the former landfill are being given a cloak of green that does not whitewash, but instead reveals conflicts.
