From terrorism to warfare, from pandemic to the security crisis, the global state of emergency pose threat to cities. When new orders are validated, the inequality is exacerbated, endangering the movement of the vulnerable. Cities become the controlling device of the authorities and become more unprotected, more distant and more exclusive for the vulnerable. Meanwhile, the imbalance between the supply and demand for space is also exacerbated. An increasing amount of urban interior, from productive space to infrastructure, become vacant. By investigating the protective framework under the state of exception, from submarines to camouflage, the project proposes the EXCEPOLIS, as parallel cities against the sedentary control. While the exceptional orders pose threats to the exterior of our cities, EXCEPOLIS unfolds the potential of the vacant urban interior to shield the autonomy. Cities within cities are established across the global context. They protect themselves by isolation and achieves their autonomy, where the ideas of distancing, property, and surveillance are exclusive. In the state of exception, EXCEPOLIS operate under alternative constitutional frameworks, where the rights of every citizen are claimed. By intrusion into the archipelago of urban vacancy, inhabitable structures subvert disjunctive cities and promote the intimate collectivity in-between the perpetual movement.
