François Pinault entrusted the design of the interior and exterior furniture for the Bourse de Commerce to Ronan and Erwan Bouroullec. Blam collaborated with Studio Bouroullec on the technical development, manufacturing, and installation of the exterior works for the new plaza, various pieces of street furniture, and the research and production of a portion of the interior furniture.

Located in the heart of Paris, the Bourse de Commerce was built in the 18th century to serve as a grain exchange, then transformed into a commodities exchange in 1889. Today, it takes on its 21st-century identity as the Bourse de Commerce – Pinault Collection, a contemporary art museum restored and transformed by Japanese architect Tadao Ando (TAAA – Tadao Ando Architect & Associates), NeM / Niney et Marca Architectes, Pierre-Antoine Gatier, and Setec Bâtiment.

On Rue de Viarmes, three 20 m² monochrome flags now welcome museum visitors. Hoisted on 13-meter masts anchored in massive 3-ton bases, these sails reflect the changing light of day and move with the wind, topped by wind-powered mobiles. All around the building, the masts are connected by five curved, 12-meter-long benches. Custom-made from cupro-aluminum, these benches follow the curve of the pedestrian street, highlighting the architecture of the site while providing seating for visitors and passersby.

For blam, it took three years to complete the studies, design, prototyping, manufacturing, and installation of the entire project. Today, this installation has been adopted as a new urban landmark, visible from Rue du Louvre and marking the intersection between the Jardin des Tuileries, the Seine, and the Centre Pompidou.
