An existing residential park in Rösslimatt in the city of Lucerne is to be upgraded. The concept for the upgrade is based on an analysis of the city of Lucerne and relates to design and socially relevant structures. The project is visualised and conceptualised with the help of augmented reality and 3D models. An organic form was chosen for the project, which meanders through the park in Rösslimatt. As a contrast to the cubic architectural style of the surrounding buildings, the serpentine lines break up the overall picture and create shelters and usable space for residents. The aspect of biodiversity is promoted by partially elevated green spaces. Other green spaces offer urban cultivation opportunities for plants by the residents.
