Mixed social housing blocks of flats where homeless and economically vulnerable people live together, which is beneficial for both groups. It facilitates access to housing more quickly for many people while the community activities carried out in the buildings promote social reintegration and break down the social isolation and stigmatisation of homeless people.

Mixed Living is a form of housing in which 70% of the people who live there are on low incomes and in need of social housing and the remaining 30% are people who are vulnerable, usually homeless people who are beneficiaries of the Housing First programme. Both parties must comply with the previously established conditions of commitment and rules, mainly regarding the care of the environment they share. Participating in this social accompaniment programme is advantageous for people in the first group, reducing their waiting time for access to social housing.

It is also clearly favourable for homeless people —and not only, because the programme is also aimed at people with a lack of social network or psychological problems— for whom the contact and cohabitation with other residents facilitates their social reintegration. In this sense, the shared housing enables proximity between the two groups with common meeting spaces that make it easier for them to have coffee, watch a football match or look after the courtyard. The project is supervised by professionals who visit the block of flats at least once a week and are responsible for assessing and managing the functioning of the cohabitation.
