This project of collective housing includes about twenty apartments. The chosen site is a parking lot situated in the district of Jonfosse in Liège. The peculiarity of the project is double. At first place his establishment which leaves to lively the negative of the old parking lot, such a ruined ground which will be reappropriated freely by the people. Secondly the treatment of the fronts, radically glazed towards the outside and completely opaque inward. The goal was to create yard totally isolated of the city, like a garden of Eden lost in Babylon.
