The project, drafted by the project team of Zulauf, Seippel, Schweingruber Landscape Architects and Hubacher and Haerle Architects, was developed successfully from an invited study assignment in 1997. The design concept is based on the conflict between the factors of time and change. While the original depression in the eastern district remains, the western district is elevated compared to the surrounding area. This is the result of the underlying contaminated sites from past times with little earth cover. To ensure high adaptability to future usage, a separate "intervention zone" was created in the park which was intended for future developments within a particular framework.
