This paper aims to investigate the capacity of the refugee admission system in Lesser Poland Voivodeship (NUTS level 2 administrative division), with a focus on analyzing a potential abrupt refugee influx to a dense urban tissue on the case of Cracow, Poland. Refugee admittance requires action in many spheres of management: legislative support, medical help, provision of essential products, accommodation, and further assimilation support. This study focuses on the so-called primary and secondary accommodation, its management and assigning process, and the actors involved. It investigates if the System Capacities of Cracow refugee admission response were enough to house all incoming persons and whether there were any new spatial structure elements introduced in order to house the incoming refugees. The paper briefly touches on the multiple facets of post-disaster built environment planning, describing not only the case of a refugee host country, but also the topic of temporary-to-permanent shelter housing in the perspective of holistic disaster recovery planning in the country at war. The study presents the concept of creating humanitarian architecture as an element of a systemic approach to the issue of emergency support for disaster victims, as well as a component of collective student action within the framework of a Polish-Japanese workshop.
