Unused private and public buildings: Re-discussing merely empty and truly abandoned situations, with particular reference to the case of Italy and the city of Milan

There is much debate today over the problem of unused buildings. This debate is often conducted in alarmed and concerned tones. Our idea is that it is indispensable to reconsider the issue with greater critical reflection and some necessary distinctions: in particular, between situations and aspects relating to public buildings and situations and aspects relating to private buildings; and, within the latter category, between totally natural and legitimate situations and truly problematic ones. To this end, we shall focus on definitory issues, quantitative issues, ethical issues and policy issues. We shall do so with particular attention to the Italian situation, which we believe is especially challenging, and to a specific case study, the city of Milan. However, part of what we shall say also applies to other contexts.
