Built in 1975 by architects Jean de Mailly and Robert Zammit, the Ariane Tower—now renovated—offers improved thermal and energy efficiency. NAOM is aligned with the objectives of the Paris La Défense business district. Indeed, the Ariane renovation project prioritized the reuse of materials and recycling, as seen in the renovation of the façade, the creation of a business center, and the redesign of the lobby. It is also part of an ESG and sustainable development initiative launched by its owner and supported by all stakeholders in this project, while preserving the identity of the Ariane Tower.

The energy-efficient renovation addresses the new challenges of the 21st century. It will highlight the tower’s key features, such as its portholes, shape, height, and concrete structure. By replacing the outdated glazing, the new façade provides improved natural light transmission and emphasizes the raw materiality of the base and the attic.

The entrance pavilion has been rebuilt to offer new services to the tower's occupants, and its exterior facilities have been redesigned to improve their usability. Interior work completes this renovation program, with the creation of meeting spaces and an auditorium enriching the Ariane tower's service offering.

• Renovation of the base: July 2022 to fall 2023
• Renovation of the facade: November 2022 to 2025
• Delivery: 2025
