This work does not deal with the reuse of CIBAs most valuable building fabric or single buildings in the area, rather it is concerned with the worthless leftovers of the disappearing industry. The proposal deals with the highly contaminated ground and translates it into a visible and persistent body within the city.

Due to 150 years of production of chemicals such as paints, adhesives, solvents and later pharmaceutical products, unimaginable amounts of hazardous chemicals were released into the ground through open storages or leaking pipes. Approximately 10% of the processed soil accumulates as hazardous waste during the cleaning process and cannot be dumped in a regular landfill. Hence, these materials —the 10%— should not be taken out of Klybeck, au contraire, it should become experienceable and visible in the developing area. Therefore two new forms —a pit and a pile— are introduced to the area.
