This thesis examines the formal and programmatic expansion of one of the most efficient generic spaces, the international airport hub, by serving the specific needs of an increasingly common mobile citizen, the medical tourist. International airport hubs are comprised of a network of interlinked corridors where large transient populations are received, held and then dispersed again. The medical tourist is a product of the rapidly increasing cost and specialization associated with medical treatment procedures. Recognizing that the density of airport hubs now rivals that of contemporary city centers, this project expands the capacity of the international airport hub, thus enabling the airport to compete for citizens in a manner similar to cities. As one iteration of a potential airport expansion system that could serve multiple mobile citizen types, this project exploits the security requirements of an existing airport and an innovative program to hypothesize a new type of airport terminal.
