    Designing secure, adaptable prison facilities

    The construction of new prison facilities is part of the French government’s drive to reduce overcrowding. We are involved from the design stage through to completion, delivering modern, adaptable and secure facilities in full compliance with applicable standards, to ensure the safety of all.

    Adapted and scalable facilities

    We optimise interior and exterior areas with innovative solutions: modular cells, functional common areas, dedicated spaces for training and rehabilitation and efficient, secure circulation. Our flexible design adapts to the needs and evolving requirements of the facilities.

    Designing facilities with respect for human dignity

    n designing and constructing our prison facilities, human dignity is one of our top priorities. Our approach ensures that accommodation and living conditions promote respect towards individuals and the safety of all.

    Delivering secure prison facilities

    Security is paramount at every stage of designing and constructing our prison facilities. Our approach incorporates innovative and proven solutions to protect prison staff, contractors and detainees and to ensure a secure, respectful and functional environment for all, including access control and video surveillance.

    Making reintegration a priority

    Rehabilitation is central to our approach. We design facilities that include dedicated spaces for education, vocational training, culture and sport, as well as social and psychological support. These features help detainees prepare for release, rebuild social and family ties and promote autonomy, with the aim of supporting a lasting reintegration into society.

Industrialised cells for security and speed

We design innovative cells as 3D concrete modules, using a unique industrialised approach. At our dedicated facility, our teams prefabricate each fully fitted cell, including furniture, electrical installations, water and ventilation systems, a prefabricated shower, a barred door and window and security systems.

This method enables faster production while ensuring optimal quality and full control over the finishes. Once completed and made weather-tight, the modules are transported by rail and/or road freight, enabling us to supply sites across mainland France.

Our fully integrated, reliable and sustainable solution meets infrastructure requirements by combining industrial performance, security and rapid implementation.

A large, light grey concrete module with a dark framed opening is central, flanked by vibrant orange industrial machinery in a factory for prefabrication.
