Le Vinci building is the building in La Défense that most clearly displays a postmodern aesthetic. Its concave facades, flanked by two uprights resembling huge pilasters, reflect a neoclassical inspiration with a baroque tendency, which Ricardo Bofill has long championed.

Led by Jean-Philippe Bridot, who is also a partner in the Bridot Willerval agency alongside Bruno Willerval, the Partenaires Architectes agency is solely responsible for the Vinci project. In 1998, it also collaborated with Bruno Willerval's agency on the Prisma tower project.
