Urban design

In urban places where alterations of institutional use prescriptions – that is, disorder – are revealed, there is often the presence of two qualities of burglary: the one that derives from a rejection of the prescription in terms of external contradiction and the one that derives from the overriding of the prescription in terms of internal contradiction. The first is positive and generates active disorder, contestation material, creative alternatives; the second is negative and generates passive disorder, oppression, brutality protected by institutional armor.
