For a public space with extensive natural elements, the most important task is to minimize intervention. Rich natural landscapes should be presented on the basis of ecological protection. In this project, top priority is attached to site protection and restoration. With respect for the natural ecosystem, original landform and cultural legacies, interactive design that serves recreational, sports and social purposes is presented. The creative design encourages engagement, restores the vitality of the site, and becomes a public space for the nearby residents again.
