In its own words, the Housing Evolutions Hub "highlights the latest innovations in the field of social, public, affordable and responsible housing. Additionally, it provides a European-wide platform for communities of experts and practitioners to share and learn from innovation challenges that are crucial to enhance and promote their housing objectives".
It includes a map of innovative housing projects from all around Europe that can be a source of inspiration for further research and stories about housing: https://www.housingevolutions.eu/project/
