The ZAC Paris Rive Gauche district, designed by architect Christian de Portzamparc, combines contemporary architecture (multicoloured buildings, hidden gardens, glass cubes) with heritage industrial buildings (the Frigos, the Grands Moulins de Paris, the compressed air factory). The Bétonsalon art and research centre is housed in a former flour market built in 1950 by architect Denis Honegger.
After a short introduction on the history of this storage building converted into a university, the artist Hélène Deléan will ask the students to imagine a new system for distributing flour in the district. Working in small groups, they will draw up a map showing the buildings, infrastructure, vehicles and roads that would enable flour to be transported. By air, water or underground, they will draw with a pen on large black paper to show these networks in negative. Each group will be asked to give details of its proposal at the end of the session.
