Is it possible to share management of common public spaces in cities in a way through which macro and micro-urbanisms can communicate? What negotiations allow a public space in the city to be characterised by the protagonism of its spontaneous use? What is needed for the lessons learnt from successful prototypes to be replicated, improved or even extended to shape public policies for the entire city? Doing it Together is a step forward, partially answering these questions by exploring and rethinking practices of city-making in a variety of contexts, analysing how scales intersect and how citizens get involved in the co-construction of public spaces. By bringing cases of public policies, legal instruments and other cooperation tools, and by identifying their obstacles, successes and results, the idea is to understand the context of each territory and how cooperation is practiced."
