ACTION AND RESEARCH ON THE PUBLIC RESIDENTIAL HOUSING HERITAGE

In Europe the public residential neighbourhoods constitute a rich and extended heritage and often tell a lively tissue still essential for the urban???s destiny. A lively tissue, for too long abandoned, that today is often characterized by obsolescence and decline and in which it???s necessary a regeneration, both physical and social, also with the aim to activate processes of urban and environmental retrofit. Some advanced experimentations in Europe (in France: PLUS+, REHA; in Germany: in Leinefelde the works of the architect Stefan Forster; in U.K.: the retrofit process of Park Hill in Shaffield; ecc) insist on interventions that can change the image of anonymous architectures through the integrations of technological and structural aspects with energy-saving and social aspects. They propose to modify the public residential neighbourhoods through interventions for additions or subtractions that fragment the buildings or enhance the surface and maybe even the total number of apartments with volumetric gains placed in front or on the roof. Following the ???Urban housing program for the renewal of the affordable fee??? of 2008, promoted by the Regione Lombardia, for the neighborhood of street Barzoni 11 in Milan was foreseen in the complete demolition and the realization of a new project that, rejected by the inhabitants, it would meet the requirements expressed in the call for doubling the number of housing. After the rejection, we were instructed to initiate a process of participatory planning and following a feasibility study by ensuring the required volumetric increase by the new municipal administration and Aler. The experimental protocol provides a multi-scale analysis on the areas that focuses on the following aspects: geometric/morphologic, physical/environmental, social/economic and civic/administrative. The protocol fits into the theme of the energetic, economic and social awareness, in the belief that an adequate analysis of the project area and an effective mapping of local data may give rise to information that will positively influence the choices of the administrators and, therefore, provide more precise input to the designers
