Paris suffers an excessive pollution caused by a transport system devoted to cars. The city lose its inhabitants. Free and potential space no longer exists. Paris is suffocating, Paris is mistaken, Paris is dying.
The city must find solutions to host its most vulnerable inhabitants, the residents of the places of detention while the public services dedicated are all going through deep crises. Inmates, homeless, refugees, retirees must be cured in the best possible conditions.
A new building must be erected in order to allow a return of the nature in the city. This radical building is the Galerie Bienvenue, abandoning deprivation of liberty, built on the Boulevard Périphérique.
Vulnerable prisoners are offered the choice to integrate this alternative prison where they will be free. In exchange, they must work and participate to the collective life. Likewise, Parisians do the same, therefore recreating the proper conditions for a social radical ecology in order to deliver the city.
