Densificazione diffusa nella città consolidata

The paper analyses normative measures which, produce urban densification effects on the urban landscape, although conceived for plural aims. It is interesting to observe the evolution in the different regional contexts, especially in Lombardy Region, which took place in two different moments. The first one concerns the introduction of the first regional law aimed at the recovery for habitation purposes of the existing attics; in a second moment devoted to the basement’s recovery. Furthermore, it is interesting to investigate the specific regional declinations of the “Piano Casa” referred to in Legislative Decree 112/2008, in the articulation of regional application models. The controversial effects of the introduction of the mentioned regulatory resources are recognizable both in terms of building growth by adding buildings to existing buildings (densification), and as an increase in the intensity of use of the building heritage through the uses variation (re-use, from appurtenant uses to residence to main uses). The application of these measures, and the debate arised about the practices generated as well as the produced effects, has subsequently solicited efforts by the regional legislators. The last efforts have the goal of reconfiguring the specific regulatory instruments provided by an organic vision expressed by “Governo del Territorio” or “containment of land consumption and soil redevelopment/ urban regeneration”.
