Covivio, a European property operator, is reinventing CB21, an iconic tower in Paris La Défense, to offer a new office experience in line with companies’ expectations and changing ways of working. This repositioning, which combines new uses, offers unique services and demonstrates a commitment to society, is already proving a resounding commercial success. The first tenant sign-ups confirm both the relevance of the model developed by Covivio and the dynamism of Paris La Défense, now Europe’s leading business district and the fourth largest globally, according to the latest EY baromete.

A marketing campaign that reflects the renewed appeal of Paris La Défense

Paris La Défense is reaffirming its dynamism and appeal to an increasingly diverse range of businesses. In 2025, more than 149,000 m² were let across 106 transactions¹, making this year the business district’s second-best performance on record in terms of the number of transactions.

This momentum is particularly evident at CB21. Since the release in March 2025 of 44,000 m² previously occupied by Suez, 25,000 m² have already been let to companies of various sizes and from a range of sectors, including manufacturing, healthcare, energy, agri-food and technology.

A range of property solutions designed to meet the changing needs of businesses

This commercial momentum also reflects Covivio and CB21’s ability to provide a tailored response to the diverse expectations of users.

To enable each company to develop a bespoke solution that combines speed of installation, budgetary control, environmental performance and quality of use, Covivio has developed a particularly flexible offering for the tower, structured around three service levels:

The ‘Classic’ package offers spaces that are immediately available in their current configuration.
The ‘Superior’ package offers refurbished, modernised floor spaces ready for fit-out, with a focus on reusing existing fittings.
Finally, the ‘Signature’ package, which focuses on the upper sections of the tower with panoramic views of Paris, allows companies to benefit from fully customised spaces with premium amenities.

Furthermore, in 2027 and 2028, a number of new facilities and services at Paris La Défense will be added to the existing range, which currently includes a lobby, an auditorium, dining areas, fitness centres and landscaped gardens:

a 500 m² rooftop that can be hired for private events, a unique space in La Défense in terms of both its size and the views it offers;
a bistronomic restaurant on the 41^st and top floor, offering panoramic views of Paris;
the “SkySuites”, modular function spaces on the 40^th and 41^st floors suitable for a wide range of uses (seminars, receptions, photo shoots, film shoots, etc.) and comprising a double-height cathedral-style lounge, function rooms, a mezzanine, a bar, as well as two apartment suites designed for corporate and event use and convertible into offices.
new conference spaces (business centre) opening out onto the gardens;
new multi-purpose spaces designed to encourage networking, events and new ways of working.

The “Signature” offering and the tower’s future new spaces have been designed by the teams at Covivio and the architect Nicolas Sisto (Sisto Studio). The project reinterprets the design and architectural styles of the 1970s, transforming this iconic tower – built in 1974 – into a next-generation workplace.

Located in the heart of Paris La Défense, right next to Line 1 and within easy reach of the main transport links, CB21 also benefits from excellent accessibility and is pursuing an ambitious environmental strategy, having already secured several certifications and set new certification targets for 2028 (HQE ‘Exceptionnel’ level, BREEAM ‘Excellent’ level, Active Score ‘Platinum’ level, WiredScore ‘Gold’ level, BiodiverCity and Osmoz).

An open living space

Beyond its architectural and service-related transformation, Covivio aims to make CB21 a genuine hub of community life, open to the wider neighbourhood.
The bistronomic restaurant and the rooftop have been designed to be open to the public, not just to those who work in the tower.
Furthermore, CB21 is committed to supporting organisations and businesses dedicated to inclusion, training and careers of the future. As such, more than 700m² is currently occupied by the “DesCodeuses” collective, which helps women from working-class neighbourhoods enter digital professions, with the support of the Covivio Foundation.
This programme reflects Covivio’s commitment to making CB21 not only a benchmark in the property sector, but also a space open to La Défense, creating social and economic value for the local area.

With CB21, we are taking a bold step in believing that an office tower today must be much more than just a place to work. We have envisaged a destination capable of offering businesses spaces inspired by the hospitality industry, a premium experience and an environment that fosters interaction, wellbeing and innovation. By incorporating a strong social dimension centred on the jobs of the future, we are also reaffirming our commitment to creating a space that is open to the local community. Initial sales figures confirm that this vision meets new expectations and is contributing to the revitalisation of Paris La Défense.
