In the midst of a health crisis, the Caisse des Français de l'Étranger (CFE), whose mission is to cover the health of expatriates, wanted to set up a reception and work space in the heart of Paris. We produced a flexible space that embraces the architectural codes of the international style, with a rigorous, airy design that echoes the CFE's mission to take over social security worldwide. In order to transform the workspace to accommodate 3 to 5 offices, we developed a hybrid form between the open-space and the enclosed office. Large sheets of glass divide the volume permanently, while additional separations are possible thanks to large acoustic curtains. Within a limited area, we wanted to offer a wide range of possible uses to bring collaborators together around their professional service.
