La città che si sgretola: nelle politiche urbane ed economiche le risorse per un’efficace manutenzione / Crumbling cities: urban policies resources for effective building maintenance

In this article, in reporting the results of a study, we try to show that a collective approach is now essential to the needs of maintenance. The thesis is: that the global economic crisis has quicken the evidence that the city model that is gradually emerging, with a difficult internal changes if it is going beyond the regeneration of the interstitial spaces, is incompatible with an idea of separation between public and private competences strictly coincident with the edge of the property; that, in the moment in which the facade is no longer the simple bark of a personal function becoming a piece of a collective mosaic, becoming a part of that common good which is beauty, culture, identity, quality, balance, order and art of the city, the it competes to the public, for its share of property, to provide to maintenance and enhancement.
