Adjacent to the Saint-Lazare Station in Paris, this mixed-use development is the work of the local practice of Jacques Ferrier and Pauline Marchetti.

The project involves restoring and rehabilitating a listed historical edifice, and raising a 20,000-square-meter, seven-floor addition. Above the lower level, the facades are covered with glass panels, using a chromatic palette inspired by Claude Monet's 1877 paintings of the Gare Saint-Lazare. Offering bars, restaurants, workspace, and green zones, the building is organized around an auditorium. The roof terrace includes an 800-square-meter agricultural plantation overlooking Paris, beehives, and a rainwater management system.
