Set for completion in 2025, The Link will rise to 242 metres, becoming the tallest building in France and a new landmark within the La Défense business district, surpassing Tour First. Developed on the former CB21 site, the project is designed to serve as the new global headquarters of TotalEnergies, consolidating its Paris operations within a single vertical campus.

The architectural concept is led by PCA-STREAM, under the direction of Philippe Chiambaretta, proposing a distinctive composition of two connected towers joined by a series of elevated “links”. These connections are not only spatial elements but structural and environmental devices, reinforcing the building’s vertical continuity while enabling large-scale façade integration.

At the core of The Link’s architectural identity is its fully glazed envelope, described by the project team as an all-glass façade. To address thermal performance, solar control, and energy efficiency at this scale, the building employs an insulating double-skin façade system. This approach allows the tower to maintain high levels of transparency while controlling heat gain, ventilation, and occupant comfort, key challenges for tall office buildings in dense urban environments.

A defining feature of the façade strategy is the integration of building-integrated photovoltaics (BIPV) directly into the glass envelope. ISSOL® has confirmed its role as the designer and manufacturer of the photovoltaic glass modules, used on the project. ISSOL supplied more than 4,000 m² of tailor-made photovoltaic glass, with individual modules reaching up to four metres in height. These large-format PV glazing elements are fully integrated into the façade system, combining energy generation with architectural expression.

The Link is officially described as the first tower in La Défense to incorporate photovoltaic panels at this scale within its façade. The project targets HQE™ Exceptionnel certification, reflecting its ambitions in energy performance, environmental responsibility, and circular construction practices.

Construction is being delivered by VINCI Construction France, with Groupama Immobilier associated as the site owner and development stakeholder. While the curtain wall contractor, IGU fabricator, and base glass manufacturer have not been publicly disclosed, The Link already stands as a reference project for double-skin glass façades and BIPV integration in European high-rise office architecture.
