This design is dedicated to contemporary and emerging music, assembling together two performance halls (1,200 and 400 places), 16 recording and training studios, spaces for digital experimentation, offices, and public spaces. On the “île de Nantes,” La Fabrique takes place on one side of the previous Dubigeon warehouse, near the Alstom warehouse (the upcoming centre of the “Quartier de la Création”) and the old shipyard turned to great gardens. This context gave Tétrarc the opportunity to gather the recalls of a place abandoned by History and remind us that Culture is continuum made of sedimentation & fertile rediscovery. History of places made of industrial warehouses.History of the techniques that built them, when science and aesthetic meet up to create a new beauty.History of the ships built with the strength skills and talents of the workers.History of artists whose eyes felt on this universe, from Monet, painter of the brand new steel structures, to the Becher who used to forgotten metallic shapes.Again, History of the industrial production organization which enable to place under the same roof an experimental workshop, an assembly line, a rectification workshop, an export site ; all those as a living picture of the concept of flexibility.The project is made of 3 distinct elements. First, the 400 Hall (with offices upon it) then the 1200 Hal : two parts connected by a public Hall inserted in the concrete post frame of the Halle Dubigeon. Finally the studios take place in a volume suspended above an old air-raid shelter.
