This book draws a line of reasoning collecting many voices around the project theme of urban interstitial spaces [In-between] in the era of globalization and di?.use city and how the discipline of Spatial Design is concretely able to give an e?.ective and original contribution.It collects ideas, re?.ections, researches and projects developed in collaboration with professors, researchers, practitioners and students, run mainly in the academia context - in Italy at the School of Design, Politecnico di Milano and in England with the University of Brighton, Faculty of Arts - while of course related to the international research and project culture.Questo libro elabora a più voci un ragionamento intorno al tema del progetto per gli spazi urbani interstiziali [In-between] nell'era della globalizzazione e della città di?.usa e di come la disciplina dello Spatial Design sia concretamente in grado di dare un proprio valido e originale contributo.Esso raccoglie idee, ri?.essioni, ricerche e progetti maturati dalle diverse collaborazioni con docenti, ricercatori, professionisti e studenti, sviluppati principalmente nel contesto del mondo accademico - italiano presso la Scuola del Design del Politecnico di Milano e anglosassone con la University of Brighton, Faculty of Arts - anche se naturalmente relazionati alla cultura internazionale della ricerca e del progetto.
