Paris La Défense Continues the Transformation of Les Groues and Seine-Arche
Paris La Défense has just taken another step forward in the development of the Groues and Seine-Arche urban development zones (ZACs). The signing of five new agreements, covering the construction of 64,000 m² of new projects, will enable the continued development of these neighborhoods to provide an attractive living environment and a high-quality urban landscape. The result: nearly 900 additional housing units.
By 2032, more than 5,000 housing units will have been built in the Seine-Arche and Les Groues areas. With the signing of these five new agreements, Paris La Défense is continuing its role as a developer in Nanterre and moving forward with the development of these new neighborhoods.
A transformation that continues in the heart of Les Groues
Nanterre’s 11th district has been constantly evolving since the first public spaces and buildings were completed in 2023. The signing of these agreements paves the way for the launch of phases 2 and 3 of the West Village project. These phases involve nearly 36,000 m² of mixed-use developments, which will help boost the district’s vitality and appeal.
Phase 2 of West Village
Phase 2 of the West Village program covers Lots 1C and 1D. The first lot will include 49 units for open-market and subsidized homeownership, along with more than 300 m² of retail space.
The second phase includes:
- 214 housing units for open-market purchase, LLI, and social housing;
- 2,922 m² of private cultural facilities known as “The Twist”;
- 1,580 m² of retail space;
- 467 m² for the Public Services Center;
- 145 public parking spaces
This new development phase is led by the developers BNP Paribas Immobilier Promotion and Marignan, in collaboration with the architectural firms Chartier Dalix (Lot 1C), l’AUC (coordinating architect and Lot 1D), Studio Muoto (Lot 1D), and Martin Duplantier Architectes (Lot 1D).
Phase 3 of West Village
Lot 1E will include 143 housing units comprising for-sale, intermediate-rent, and public housing. This project is being developed by BNP Paribas Immobilier Promotion and Marignan, in collaboration with the architectural firms l’AUC, Martin Duplantier Architectes, and Ignacio Prego Architectures.
The projects are part of a low-carbon approach that promotes mixed-use development. As such, they aim for high environmental performance.
The agreement with SNCF Immobilier is coming to an end
Last May, Paris La Défense and SNCF Immobilier signed an agreement for the final transfer of the public group’s railway rights-of-way in the ZAC des Groues, covering approximately 1,500 m². This transaction marks the conclusion of a memorandum of understanding initiated in 2015, covering the gradual sale of 17.5 hectares of land—representing 70% of the developable land in the ZAC des Groues.
The Groues Neighborhood by 2032
By 2032, the Groues neighborhood will have:
- 4 hectares of public green spaces
- 10,500 residents
- 12,000 employees
- 5 km of bike paths
- retail stores and public facilities (schools, daycare centers, gyms, etc.)
Following the launch of the RER E line in 2024, by 2032, the neighborhood will also be served by Line 15 of the Grand Paris Express.
The final phase of development for the Seine-Arche ZAC
The last two agreements concern Lots B, CDE, J, and K, located in the Franges de l’Université area within the Seine-Arche ZAC. They will enable the completion of the final construction projects while creating new public spaces.
The first project involves the creation of a residential complex for researchers, young professionals, and students, led by the Pichet Group and SOA Architectes. It will include 120 housing units and will also feature a café-style business on the ground floor.
Located near the A86, the Nanterre-Université train station, and the T1 tram line, a mixed-use development is set to be built. Spanning three buildings, it will house higher education facilities, spaces dedicated to sports and recreation, facilities for the social and solidarity economy, a hotel, and a student residence. This project is led by Kaufman & Broad, in collaboration with the architectural firm Emmanuel Combarel Dominique Marrec Architectes (ECDM).
