Enhancing the Historic Public Social Housing through a User-Centered Design-Driven Approach

The study presents a didactic experience for the deep refurbishment and the revitalization of the San Siro neighborhood in Milan (Italy). The public housing is a significative example of the 20th-century architecture (also named “Italian Modernism of Architecture”), designed by the Italian architects—Franco Albini, Renato Camus, Giancarlo Palanti, and Laslo Kovacs (1938–1941). Nowadays, it is a multicultural area, characterized by the presence of a fragile population, with strong socio-spatial inequalities, intercultural and intergenerational conflicts. Here, an architectural design project is realized, experimenting with innovative and up-to-date design solutions. This experience develops a sensitive awareness of the multidimensional complexity of the environmentally responsible design, which requires a critical balance among dierent disciplines and skills. The reusing of existing buildings has sustainable importance for preventing new land-uses and for saving the potential energy consumption related to the construction process. Only a widespread knowledge of the local socio-economic conditions through participatory actions permits the selection of appropriate retrofit solutions, considering also the high cultural, social, and economic values. Functional and social mix, space flexibility, green design, renewable energies, circular economy criteria, and continuative maintenance are the correct strategies for boosting the social revitalization and for improving fairness, safety, architectural quality, human comfort, energy eciency, and sustainability in this public housing neighborhood.
