In the field of social housing, practices of the residents are often badly taken into account (Faure, 2001). During the 1960s and early 1970s, in North America, the municipalities initiated a variety of programs of citizen participation (Cole, 1974). But, the typical community rarely participates in the architectural or urban design. Social alienation and inhuman environments are a common condition of urban life (King, 1989). Moreover, the quality of social housing is often concentrated on the aptness of the architectural models or prototypes. The interest on quality of the urban shape in the residential neighbourhoods is relatively recent. Indeed, although some precursor projects were born at the beginning of the eighties, it is only at the beginning of the nineties when real concerns about urban characteristics of residential neighbourhoods were born. Nowadays, the urban design could be perceived like a field of knowledge where different analyses and theoretical methods can be joint to be applied in a complementary design process. The research team refers notably to the application of the urban morphology analysis and the New Urbanism values in a sustainable development perspective. That is, the principles and techniques of true urban design may have been forgotten, but they can be relearned (Duany & al.2000). Therefore the importance of the design inspired by the typomorphology principles and the New Urbanism values, that aims to restore a convivial dimension to the urban neighbourhoods with a participatory process of design. Finally, sustainable development refers to a perspective of development that does not call for short-term corrective measures.
