This report attempts to explore the causes of spatial incoherency in Hillegersberg Zuid. It does this through a retrospective historical analysis of the infrastructure, its symbolic projections and its use. Through the lens of socio-political motives of the past century the cities’ response to the current housing crisis is questioned in the area along the Ceintuurbaan, RET and St. Franciscus Gasthuis, designated as a search area for densification by the Municipality of Rotterdam. The existing functions service a larger framework yet present as isolated blocks disconnected from their immediate surroundings. (Re)developing this physical, economic and socio-political border has the potential to create a permeable boundary and allow for more diverse interaction. By searching for an approach in which the existing structures are integrated into a sustainable densification of the area a proposal is presented through physical models and design research in a concept to reconnect the fragmented area
