According to the most recent data from the United Nations High Commissioner for Refugees, in 2020, 82.4 million people were forcibly displaced. In addition to this situation, in the developed world, building construction consumes 40% of the world’s material resources and primary energy, while the construction industry generates 35% of industrial waste and 40% of total global emissions. Therefore, the objective of the research is to propose an eco-efficient prototype for emergency housing, from the point of view of circular economy and regenerative sustainability, that can respond to situations of natural or humanitarian disasters. To achieve this, it will be necessary to identify the problem that must be answered and develop a theoretical model that will serve as a guide for future interventions of these characteristics. Finally, to verify the applicability of the developed protocol, a field work is executed in an unorganized settlement, Subaşi camp, located in Turkey. This research presents a novel prototype that could be used as an alternative to current emergency housing, not only responding adequately to the minimum standards of habitability, but also doing so in an eco-efficient, environmentally correct way and promoting the Sustainable Development Goals and circular economy established in the 2030 Agenda.
