Nanterre Partagée - CASH Site

Construction of first-time ownership housing, COHAB shared housing, a residential hotel, a nurses’ residence and a Montessori school, along with redevelopment of a building comprising mixed uses including entertainment and Social and Solidarity Economy functions.
The ambition of the Nanterre Partagée project is to free up and open the CASH hospital site, which has remained bottled up, and make it accessible. We hope that this site, currently perceived as a closed compound, will be made accessible to the people of Nanterre by offering new use types. The project is in continuity with the public space thanks to open spaces that will house new practices aimed at the inhabitants, hospital staff and local residents. Our vision, oriented towards users, is to create a place that is pleasant and attractive. Comfort, health and well-being will be the central concerns, along with the permanence of the interior and exterior spaces.

Restructuring a hospital and opening it to the city is no ordinary task. Therefore the project that will emerge must be worthy of the challenge. The challenge is to orchestrate the evolutions and needs of the population while respecting the history of the site.
It was those needs – those of Petit-Nanterre and its inhabitants – that we analysed and endeavoured to meet:
- the need for green spaces;
- the need for activities for all citizens;
- the need for accessible and diversified housing;
- the need for social and functional diversity.
These needs, along with the choice of the individuals who will make it a vital place over time, are what guided our planning.
Our innovative planning for building 23 of the CASH, which is to be preserved and is currently called “La Flânerie,” encourages openness to other users, including citizens of Petit-Nanterre, local associations, those engaged in the Social and Solidarity Economy and new economic players in the region.
This innovative planning is also meant to contribute to promoting the well-being of all current and future users, including the most vulnerable ones, and to respond to the challenges defined by the Hôpital Territoire Promoteurs de Santé approach. Accordingly, our goal is to promote development that is inclusive, sustainable and equitable by endeavouring to maximise its positive impact.
The project we propose for the La Flânerie building includes several determining criteria identified by the ARS (Regional Health Agency), such as:
- local economic development;
- social practices and meeting places;
- mobility and the practice of physical activity;
- public spaces and nature in the city, etc.
Apartments with a plurality of uses, flexible, scalable – such as specific typologies of duplexes and 3-room lofts that respond to the evolution of living situations by including a modular living space, or the Homdyssée concept, which enables a home to be reconfigured in a reversible way.
