VINCI’s new head office in Nanterre, l’archipel, brings together nearly 3,500 Group employees and is a showcase for environmental performance and quality of life at work. Designed by Jean-Paul Viguier, in collaboration with Marc Mimram, l’archipel comprises five buildings, four of them linked by footbridges, reflecting the diversity and collective spirit that are part of VINCI’s DNA. Represented by VINCI Immobilier for the development, the Group has entrusted the main work for the construction to VINCI Construction and VINCI Energies.
This mixed-use complex, which is mainly composed of offices (74,000 m2), includes numerous service areas – restaurants, the concierge service, a sports hall, a media library, a health center – and commercial premises (1,500 m2). One of the buildings is located next to the future Eole station in Nanterre-La Folie, opening up l’archipel to the city. By building its headquarters at the gateway to the new Les Groues district, VINCI is contributing to the redevelopment of this rapidly changing area.
The project’s strong points include:
In line with VINCI’s environmental ambitions, l’archipel has been designed as a demonstrator of the Group’s know-how, particularly in terms of the ecological performance of buildings and the integration of new technologies.
Its design incorporates the challenges of the circular economy, recyclability and maintainability of the components of both the construction and the development. Anticipating the RE2020 regulations, l’archipel has achieved ambitious objectives in terms of environmental labels and certifications

The first commitment made on this project in terms of circular economy consists in the selection of materials and products compatible with biological or technical cycles and consistent with the Cradle to Cradle philosophy.
For this, the project team relied as much as possible on the Cradle to Cradle certified products Standard and introduced the notion of „C2C potential“ products („C2Cpotential“). This was used to make a conscious choice of materials based on criteria that contribute to their circularity and positive impact. A „C2C potential“ product thus verifies the following criteria, based on declarations by the manufacturers:
The project uses a circular material library. This tool makes it possible to maintain the value of the resources that go into the composition of the building, by creating ecosystems of recovery and revaluation of the material. To achieve this, the team relied on research on the circularity of buildings to propose the creation of „circular passports“ for products. The circular passports are true identity cards for the products used and include all the information needed for the circular use of resources, such as the composition of their materials, recommendations for use and maintenance, recommendations for a second life (upcycling, recycling, etc.) and the estimated value at the end of the period of use.
All the information is integrated into the digital building model (BIM – Building Information Modeling). The Facility Management company thus has at its disposal all the information on the composition of the materials or equipment used, their quantity and their location in the building.
The material library implemented on l’archipel and integrated into the BIM will allow for the recyclability of materials in the operating phase and in the case of future restructuring of the building complex. The maintenance of the buildings will be facilitated, thanks to the use of the material library integrated to the BIM.
The Mona building serves, within l’archipel project, as a demonstrator of the Vinci Group’s knowledge in wood construction. Indeed, ARBONIS, a subsidiary of the VINCI Group, deployed the wood-frame wall solution for the façade. The building also has a wooden structure for the cafeteria on the 6th floor. This part of the project highlights the advantages of wood construction, namely:
This element promotes the use of wood in the realization of buildings through the demonstration of a successful integration of wood in facades and structural elements.
