Campus
Generous workspaces able to accommodate a large number of employees and provide a wide range of services.
In 2003, Covivio acquired 18 hectares of land in the Vélizy-Meudon district. Since then, in line with its strategy of developing turnkey scalable campuses for key accounts, Covivio has developed campuses for Thales, Dassault Systèmes and Eiffage (33,000 m² sold at the end of 2021), as well as the Ducasse Education campus (5,100 m² sold in 2023).


Vélizy-Meudon is the second largest commercial hub in the Paris region housing nearly 50,000 employees and 1,000 international companies. This attractive district forms an integral part of the Paris-Saclay science and technology cluster, which meets companies’ current demands for diversity, accessibility, performance and services.
In 2008, Covivio delivered a 56,560 m² turnkey campus to Dassault Systèmes. The partnership continued in 2016 with the completion of an initial 12,800 m² extension, then again in 2020 with the construction of a new 27,600 m² building delivered mid-2023.
The 96,000 m² of office space is backed by a comprehensive range of services: numerous catering areas, several sports facilities and gyms, accessible rooftop terraces, a conference hall, showroom space, and more.
In 2012, Covivio signed an agreement with Thales for the development of an initial campus named “Hélios” measuring 46,750 m² and delivered in 2014. It was built alongside an earlier historic 41,520 m² Covivio building occupied by Thales on the adjacent site.
Surrounded by 10,000 m² of landscaped grounds, Hélios offers users over 10,000 m² of service facilities including a 400-seat conference hall, a business centre, a fitness room, a concierge service, various catering areas, a training centre and the “Thales Learning Hub” university.
In addition to its comprehensive service offering, Hélios features functional, bright and ergonomic work and relaxation areas with interior design by Saguez & Partners.
On 9 July 2026, Covivio handed over the keys to Azur to Thales, marking the culmination of nearly four years’ work. Developed at the heart of the Vélizy-Meudon campus, this new building, covering nearly 38,000 m², has been bespoke-designed to support Thales’s high-tech operations.
Intended to gradually accommodate more than 4,000 employees from the Land and Air Systems (LAS) division, Azur brings together office spaces, development platforms, secure data centres and showroom areas. The complex is complemented by an integrated range of services and nearly 9,000 m² of landscaped areas.
Designed to the highest performance standards, the building is aiming for HQE Excellent, BREEAM Excellent, OsmoZ and R2S certifications, illustrating Covivio’s commitment to sustainable, high-performance property suited to new ways of working.
