In 2026, the architectural firm AT architects, consisting of Céline Teddé and Jérôme Apack, completed the OMNES Campus in Marseille, located on Place Marceau in the city's 3rd arrondissement. The campus is part of the Saint-Charles ZAC, a large urban development zone aimed at revitalizing a previously underdeveloped area of Marseille. It brings together three institutions from the OMNES group: ECE, INSEEC, and Sup de Pub. The project covers 6,200 square meters of usable space, though the budget remains undisclosed. The campus contributes to the ongoing transformation of Marseille's urban landscape by integrating into the existing neighborhood. The OMNES Campus is positioned at the edge of Place Marceau and is supported by the Euroméditerranée development agency. The building is registered under the perimeter of the Architect of the French Buildings, an organization responsible for overseeing architectural projects of national significance. The design incorporates traditional Marseille architectural elements, particularly the "three windows" typology—narrow, multi-story buildings common in the city—while also integrating with the more modern structures that now define the area. The building's design emphasizes a smooth transition between its interior and the surrounding urban environment. The rhythmic arrangement of its facades and the progressive unfolding of the structure create a sense of continuity with the city. A series of accessible terraces extend the interior spaces and guide visitors through the campus. Inside, a central vertical space promotes interaction among students and different academic disciplines. As one moves through the building, the design offers changing views of the surrounding area, including neighboring buildings, Place Marceau, and the broader cityscape, creating a dynamic visual connection with Marseille. The campus was developed with an emphasis on sustainability, aligning with the broader low-carbon strategy of the Saint-Charles ZAC. The architects used a prefabricated concrete framework combined with locally sourced materials, such as compressed earth from Marseille and stone from Vers-Pont-du-Gard. This approach supports environmental goals while ensuring construction efficiency. The structure also allows for flexibility, as the ground floors can be adapted for retail, and upper floors can be converted into offices or housing in the future. This adaptability ensures the campus can evolve alongside the neighborhood's needs.
