Located on Saint-Sacrement Street, in the historic district of stock exchanges and major companies, the building occupies most of a U-shaped urban block, featuring an elegant cour d’honneur on its main façade. With six floors and a flat roof, its steel structure even surpasses later ten-storey skyscrapers. Built from non-combustible materials such as steel, brick, stone, concrete, and terracotta, the main façade is clad in cream-coloured Indiana limestone, while the rear, facing Le Moyne Street, is finished in beige brick.
Perfectly symmetrical, the building consists of a central block and two wings forming the cour d’honneur, which provides access to the imposing main portico. All façades follow a tripartite division: a rusticated base, an unadorned middle section, and an upper section with columns and pilasters linking two floors beneath a copper cornice. This classical language, complemented with details inspired by ancient Greece—such as the in-antis Ionic portico and the decorative frieze with Greek motifs—reflects the influence of the École des Beaux-Arts in Paris and the North American classical revival of the early 20th century.
