Reinventing a Metropolitan Productive Territory.

The former PSA factory in Aulnay-sous-Bois is one of the largest post-industrial sites in the Greater Paris region. Since the plant closed, the site has gradually welcomed new activities—including logistics, data centres, geothermal energy facilities and the future Grand Paris Express operations centre—yet without an overarching vision. The project transforms this succession of individual developments into a coherent urban strategy capable of supporting the site’s long-term productive transformation.

Rather than starting from scratch, the masterplan builds upon the site’s existing structures. Roads, infrastructure, retention basins, landscape corridors and available land become the framework for a gradual transformation. Recycling already urbanised land, restoring ecological continuity and creating public spaces adapted to productive activities improve both economic performance and the quality of the working environment.

The project establishes a flexible framework capable of accommodating change over several decades. A coherent network of public spaces, a continuous landscape structure, a clear mobility hierarchy and strong connections to the future Grand Paris Express station provide the spatial consistency needed for a territory that will continue to evolve alongside new economic opportunities.

More than the redevelopment of a former industrial site, the project demonstrates how a large productive district can become a genuine piece of metropolitan city: a place where industry, infrastructure, landscape and mobility work together to create a new model for productive urban development.
