Interventi per il tessuto urbano di Ortigia(SR): la reversibilità come parametro per la selezione delle tecnologie di intervento

In the last twenty years, the Municipality of Siracusa has been managing a complex urban spaces rehabilitation process, enjoying of extraordinary financial resources and of an appropriate coordination strategy between all the authorities involved. A urban unitary image saving the existent identity, has been defined as the primary aim for any rehabilitation operation. Starting from a study on local materials and ancient technologies, acceptability thresholds for restore and requalification interventions have been defined. Taking into account cultural strategies behind restore interventions realized on urban empty spaces of Ortigia, the research defines design scenarios as a sort of pursued vocation that can be achieved with an appropriate selection of materials and technologies. Assuming the Piazza Duomo restore operation as a case study, the research comes to a performance grid, affording on reversibility of the design solutions.
