The development of affordable urban housing, historically, has been linked to the process of industrialisation and the contextual urbanisation of the labour masses (Arku & Harris, 2005; Morgan, 2005). The transformations produced by the shift from the industrial to the post-industrial era involved profound changes in the city, and the stock of public housing built during the industrial era is now often obsolete, showing its limits not only in terms of construction, materials and technology, but also at the urban, social and economic levels (Kennett, 1994). The problem of regenerating or re-building important stock of social housing, which have became increasingly obsolescent and unpopular, requires specific responses from policy-makers and social housing landlords (Hall & Hickman, 2005), and can play a major role in the urban transformation to adapt to a post-industrial and sustainable era (Smith 2006).Numerous factors indicate good practices for contributing to sustainable housing regeneration (Winston and Pareja Eastaway, 2008), however their synthesis in a project process appears extremely complex.The integration in the urban context, or, more often, the lack of integration of the architectural and urban form, is the factor that probably contributes most heavily to the stigmatisation of the social housing areas (Blanc, 1993). The ghetto-effect due to the concentration of low-income households is among the most frequently recognised urban character of public housing areas (Priemus and Dieleman, 2002).This study analyses the sustainability of different responses to the problem of obsolete public housing, particularly focusing the perceived values and meanings of home, (a) as abode/house, (b) as living environment (immediate surrounds and neighborhood) and (c) as where I come from (home town, etc).Looking at three case studies in Italy, Belgium, and France, it discusses competing strategies for approaching the regeneration processes, studying the impact of political, spatial (urban and architectural), social, psychological, economic factors on the social and cultural values of ‘home’.The case studies show that sustainable regeneration projects of obsolete public housing encompass multiple levels of complexity, and therefore the criteria for the decision making are numerous and can be contradictory. The social identification and the socio-cultural values take particular account of the role of the place in generating references of identity (we belong to that settlement); extending the meaning of ‘home’ and challenging the boundaries between private and public action; and the embodiment of the memory of the place. The successfulness of the regeneration project in addressing these factors, and in enhancing and extending the meaning of ‘home’ and a shared perception and sense of responsibility and ownership between residents appears to be a key factor for a regeneration sustainable and successful at various levels.
