Building on work carried out in previous projects, proposals will study, refine and validate existing engagement approaches, that allow residents, businesses, cultural organisations and local governments to co-design and co-create public spaces in neighbourhoods. For instance, this should include how to involve citizens in the development and maintenance of public spaces and neighbourhoods; or flexible designs allowing communities to re-create or re-furbish spaces according to evolving needs. Special attention should be paid to involve diverse groups and citizens at risk of exclusion.
