Housing refers to much more than a building: the quality and accessibility of housing have social, economic and cultural repercussions for cities. Housing policies influence social diversity, participation in civic life, and residents’ access to public and local services, and have a major impact on quality of life in the city. Propriety forms and their monetary value are also determining factors. Whether it be through land trusts, housing cooperatives or housing for target populations in need, the SSE has shown itself to be a key partner of local governments that are seeking to design and implement projects to facilitate access to housing in the short and long term.
