The Linéa borders the circular boulevard and features a long reflective glass façade. The façade is divided by white posts and crisscrossed by red window frames. However, the building derives its originality from its irregular shape and the importance given to the rear base, which provides access to the circular boulevard.

Michel Andrault (1926) and Pierre Parat (1928) joined forces in 1957 and occupied a prominent place on the French architectural scene for nearly forty years. Known for their work on housing (the Pyramides d'Epernay and Evry), they also designed major facilities such as the Palais Omnisports de Paris-Bercy.

In 1985, they entered La Défense and, like Henry La Fonta, established themselves as the most influential architects on the site. They accompanied its transformation for nearly ten years and designed several master plans. In terms of achievements, Michel Andrault and Pierre Parat participated in a dozen projects, including the restructuring of the CNIT and Le Michelet-Gan Groupama. In 1997, the Renaissance Hotel marked their last collaboration. Michel Andrault then continued his career by founding the Conceptua agency with Nicolas Ayoub.
