Masterplan, refurbishment and construction of a campus for Stellantis in Poissy: Offices, R&D Centre, and multi-storey car park.

As part of its reorganisation, Stellantis freed up industrial space and wished to make use of this space to set up an tertiary sector and R&D campus.
The campus consists of office buildings articulated around a "social condenser" and linked by covered streets, an R&D building, landscaped outdoor areas, and a multi-storey car park.
Designed to be long-lasting, the campus is primarily designed to house Stellantis' activities, but because of how it is divided up, it can be used by different users.
From an architectural point of view, the project is anchored in its urban ecosystem, it offers flexibility and proposes a different user experience with the convergence of real-world and digital pathways and adapted uses.
