The demand for shelter provision to vulnerable populations today, is bigger than ever. Natural disasters, as well as violence and conflict, drive whole communities to seek a home, everyday. To be more specific, 1 in every 113 people on earth is displaced, while 1 in every 7 lives in inadequate settlements. From the refugee camps of thousands in Asia, Europe and Africa, to the Latin American favelas and the transitional accommodation camps where the displaced by natural disasters live worldwide, the built environment includes the concept of impermanence. In an attempt to improve the temporary conditions of living and to proceed to healing, it is very important to include the design factor. Through design, effectual, cost-effective and immediately applicable solutions can be promoted, in order to help the communities recover and reconstruct.

In this paper, there is an analysis of the displacement phenomenon and the response to that, as well as the way architectural design can contribute to dealing with emergency situations. At the same time, the architects and projects which have influenced the disaster response field are highlighted. Lastly, there is a presentation and research of projects and proposals for transitional shelters and permanent housing for refugees and  those displaced by natural disasters.
