HIGH PARK is a multi-functional extension for dense european cities with lack of green areas. The aim is to combine qualities of a classic park with additional public functions to strenghten local communities. A vertical structure provides open space for different functional programs on several levels, which are extended with large terraces, balconies and roofs. The green areas invite the local inhabitants for social activities in a surrounding of unknown possibilites. Furthermore the dense green vegetation improves the local micro-climate and air quality of the surrounding.
