We see this in the flexible open building concepts of John Habraken, the simple modular housing system of Walter Segal, the self-build and self‑management theories of John Turner, the cooperative strategies and ‘pragmatic anarchism’ of Colin Ward, the tecnica povera of Riccardo Dalisi with children from the Traiano Quartiere in Naples, and the ‘action planning’ of Otto Koenigsberger in India. Besides a common concern with the groups or ‘users’ most often marginalized or excluded by formal processes of authority and control, these projects are linked by a modesty that contrasts starkly with the heroic projections of the modern movement. It is a radical urbanism characterized by sensitivity to scale and time, an appreciation of context, and a shift from author to enabler.
