Subject of the competition is the design of a residential complex of social housing extended over 9,000 sqm, plus integrated residential, commercial and urban services. The main objective is to design a building complex integrated with the existing neighborhood but at the same time is characterized by its own identity by creating a new local centrality. The project proposes a housing model based on the concept of “small clusters”, following which the different units are aggregated by type in order to avoid phenomena of social tension. The lay-out of the buildings maximizes the common areas not only from the physical, but also from the visual and functional point of view and minimizes the number of stairways and elevators that distribute on average 5 or 6 units that form a small cluster (of about 20- 25 people) to increase socialization and sense of collective solidarity and create a real neighborhood. This integrated approach of social character is practically achieved through the disposition of buildings that can be described as double slats rotated by 15 degrees along the heliothermic axis; the central corridor swells until it assumes the dimensions of an open courtyard for physical and social hygiene reasons. Within the inner courts are located open stairways and walkways connecting the two opposite buildings..
