Referring to our psycho-sociological research and to several years of reflexive interviews with adolescents, I analyze the way in which the housing project, a space for daily living and belonging, constitutes both a place of refuge and a risk of fixation. In the face of stigma, the adolescent peer group welcomes and protects; it also represents a place of confinement, both in the psychical sense and the sense of material survival. Getting out of the projects requires important steps made up of failures and successes. All leave this adolescent situation, the paths are many, and the recourse to Islam is more and more one of the ways.
