This thesis inserts a new urban typology into the city, shifting spatial, political, and programmatic boundaries by constructing a new extraterritorial ground. Extraterritoriality, the state of exception from local jurisdiction, is not yet formally manifest as an urban architectural problem. The proposed ExtraTerritorial Typology [ETT] is an urban architecture that reconfigures the boundary conditions between territorial grounds and user groups: displaced populations and local citizens. Mediating between global and local scales, the ETT relates to its urban context despite its bigness. The ETT demarcates its non-vertical boundary in relationship to the existing ground by strategically connecting to and detaching from the site topography. The ETT accommodates a spectrum of multiscalar international programs within venues of emplacement and displacement dispersed in topographical bands across the site. As an urban scale site intervention, the project is a megaplane which interacts with the existing ground. Sometimes a surface condition, sometimes as megaobject, it is perceived from the street as a shifting architectural form. It extends from the urban context to accommodate programmatic spaces of individuation and collectivity, from transit to asylum, privatized medical treatment to public athletic stadia.
