“…Empirically thorough approaches to processes and actors of public space production are neither new nor incompatible with normative and critical standpoints (e.g. Levine, 2002;Mitchell, 2003). There are numerous studies on the spatial and political logics of public space policies and their implementation, including an identification of the different normative views at play (Betin, 2001;Dessouroux, 2006;Fleury, 2007;Jacob and Hellström, 2010); on the impacts of participatory techniques (Söderström et al, 2001;Vareilles, 2006); on the gradual definition of public space projects and regulation practices, including investigations of the locus of decision (Calderon and Chelleri, 2013;Ehrenfeucht and Loukaitou-Sideris, 2007;Smithsimon, 2008); on the circulation of policies and design and management models (Didier et al, 2013;Söderström and Geertman, 2013;Ward, 2006)… These works have demonstrated how actual production processes are defined by contingent, and therefore unique, interactions between autonomous actors and a set of political, technical and organizational constraints operating at different scales.…”
