A smaller study of how to work with a contaminated piece of land. The project consists of a containment and a decontamination strategy that involves the user in the process of the decontamination. This is done by making the process into an architectural element that shows the areas in need of protection and the area that is being decontaminated. A walkway on the perimeter of the contaminated area changes orientation from outside the circle to the inside and back again outside, as you walk along the path. Three resting platforms marks the middle of the orientation and exhibits the nature. In order to decontaminate the soil, willow trees have been planted, so over time, they can be harvested and slowly remove the contamination in the ground.
