Trailer of a documentary on post-war industrialized housing. The story of the Dura Coignet factory at Heyplaat, Rotterdam is told by the sons of its creators Groosman & Dura. Former residents relate how the modern flats were an upgrading of living conditions. The question is raised what is the future of the concrete slab buildings? The project is inspired by the documentary 'alle vogels hebben nesten' (all birds have nests) thatLouis van Gasteren made about the Dura Coignet factory in 1963 [see youtube.com/watch?v=GjrQ5ZRmW8U].
