The art of inserting a building into an historical city block means engaging in an open, physical dialogue with those already there. Building onto an extant structure also presents an opportunity for a more widespread renovation project, a reclaiming of space. The new headquarters of the Fondation Jérôme Seydoux-Pathé is an unexpected presence, a curved volume one glimpses floating in the middle of the courtyard in which it sits, anchored on just a few supports. On the ground, there is a stand of birch trees, a floral island set in the dense mineral context of the city.
