Owen Hatherley’s Walking the Streets, Walking the Projects proposes the theory that, “in the 1960s, a new ideology emerged in New York. It held that cities thrived through the spontaneous ‘ballet of the streets’ and died when the state erected sterile projects.” This premise is then tested through a travelogue. Lynnette Widder, professor at Columbia University and author of Year Zero to Economic Miracle: Hans Schwippert and Sep Ruf in Postwar West German Building Culture, discusses Hatherley’s book recently published by Repeater Press.
