This thesis aims to investigate the potential of design as a tool for mediation within the dimensions of social spatial systems architecture takes form in, focusing on the specific case of Al Qursaya Island in Cairo. This is done through the exploration of small-scale design systems that address the issues of territorial mechanisms. Positioned at the nexus of urban density and rural self-sufficiency, Al Qursaya faces dual pressures: the threat of eviction due to its high-value land status and the community's reliance on self-sustaining livelihoods amidst limited infrastructure. These tensions are compounded by competing stakeholder interests—government aspirations for tourism and economic gain versus residents’ desires for security, autonomy, and livelihood preservation.
