Following an international consultation, the architectural, technical, and environmental design for the new Saint-Gobain Tower was created by the Valode & Pistre agency. Its design is crystalline and airy, evoking Saint-Gobain's historic business: glass. Since 2020, the Saint-Gobain Tower has been Saint-Gobain's global headquarters. It also features balconies and terraces that are fully accessible to tower users, and its base comprises a showroom space housing shared services, catering facilities, and an auditorium. The top of the tower, on the 37th floor, is called Espace Plein Ciel (Open Sky Space) and is dedicated to events, offering panoramic views in a cozy, green space.

It is located on the site of the former Iris building, which was demolished in 2016 to create a larger forecourt. At the same time, Paris La Défense, the developer and manager of the business district, has redeveloped the entire neighborhood.

In 2020, the tower received the Geste d'Or Architecture, Innovation and Materials award. This prize recognizes the innovative construction techniques used, the bold architecture, and the tower's glass envelope. In 2021, the Saint-Gobain Tower also obtained the four main international environmental certifications, with the highest scores. It was recognized for its environmentally-focused approach.

Denis Valode (1946–2025) and Jean Pistre (1951) founded their agency in 1977. Within 20 years, it became one of the largest in France. Its success was due in part to the reconstruction of the Lainé warehouses in Bordeaux and the construction of the L'Oréal factory in Aulnay-sous-Bois. Today, the two architects are particularly involved in the design of towers—in Saint-Denis, Lyon, Beijing, and Mumbai—and sustainable development.

The tower is divided into three rhombohedrons, cubes whose faces are not square but diamond-shaped. The base houses a showroom, showcasing the company's expertise. The sculptural body is designed according to a set of horizontal and oblique lines, with an almost musical rhythm. “Such an architectural object cannot escape observation. It must have a poetic dimension. Emotion creates acceptance,” comments Valode.

Each floor has a terrace with a garden, like cavities carved into the façade. An undeniable technical feat, the top of the tower takes the form of a 40-meter-high greenhouse, perched at an altitude of some 150 meters. Made of electrochromic glass, its second skin can change color to protect from the sun.
