LAN architecture has inserted a minimum security prison composed of a CSL (centre for parole) and SPIP (prison service and probation) into nanterre’s residential fabric. the project elevates the presence of industrial buildings that pervade the site with a punctured monolithic volume and streamlined rectilinear layout. the prisoners’ spaces are separated both actually and visually from the community with an L-shaped plan that enables the concrete envelope to remain somehow unobtrusive. the robust mass is skinned in sheet metal, lending the building a solidity that buffers both sound and sight between the confined population and inhabitants of the french town. small shutters fold or slide open to reveal offices; however, a south-facing opening renders the massive structure relatively lightweight. this void marks the entrance to the facility’s parole office, the space that both grants and manifest a version of freedom and subtle confinement. while the office is protected inside the site, choice fenestration creates an open volume and a porous skin wraps round the whole of the building.
