The urban space, considered mainly as a transition space by some people, is nevertheless a living space for others. Architecture and furniture flourish here that will be identified as "architecture of rejection”. But what is rejection? Where does it come from? And what consequences does it have on our actions? In a period when the “urgency of social relationships” is important, I decided it was necessary to examine this question. Mixing sociology and architecture, this dissertation looks at the topic from a global point of view, then focuses on a specific case: homeless people, generally considered the most excluded group. How can architecture express exclusion, and towards whom? What are the ways forward for the city of the future, an inclusive city?
