laboratory concern social support actions related to the urban regeneration project of the neighbourhood promoted by the Lazio Region and Ater and the urban renewal action of the 'piano libero', the so-called 'Quarto Piano'. This is the project 'Il Chilometro Verde' [5], which consists of social housing construction where services were offered instead.

The designer Mario Fiorentino intended the 'Quarto Piano' for services, collective spaces, professional studios and urbanity. Those who lived on the upper or lower floors (the fourth floor also coincides with the change of building type from terraced house to the bannister's house) had to find themselves in a building in the city. The history of Corviale's 'Quarto piano' was different. Immediately after its construction and more and more over time, this space was adapted to the needs of a diverse population with different housing conditions, sometimes even with distant origins. These additional living spaces became inhabited and somehow became houses. The census had counted 135 households, but the regeneration project came up with 103 instead, a number lower than that of settled households but higher than those eligible for social housing. Families who had applied to the municipality of Rome's 'Bando Speciale' and met the requirements for social housing allocation are eligible for a new flat (73 applications of which 47 were accepted and 26 were not). The social support activity implemented by the 'Laboratorio di Città Corviale' aims to promote the 'Quarto Piano' regeneration project. This activity foresees the involvement of the current occupants of the illegal houses in the rehabilitation process. There are three moments in which the project will be carried out: the temporary departure of the occupants, for the time necessary to renovate the building, and then, only for those who have the requisites, the return to the new home. For those who do not have the right to return, the accommodation outside the neighbourhood remains and the temporary accommodation in one available Ater flats.
