The regeneration of degraded spaces is the most concrete expression of sustainability: it conserves building capital, avoids new construction, reduces land consumption and embodied carbon emissions and returns use value to the community. The reuse of the former Benedictine Church is the objective of this thesis. The project focuses on the functional redesign of the building, but at the same time opens up broader scenarios of urban regeneration, with the aim of restoring value to an area currently characterised by neglect, decay and a general state of decay. The project aims to create a unique auditorium, designed to host musical, cultural and performing arts events, in line with the history and spirit of the place.
