To be well in towns and cities. From the quality of the space to the well-being of the inhabitants - The construction of a new approach to ‘urban well-being’ begins by reconsidering the space-well-being relationships established by traditional urban planning, which have long been fossilised in the standard practices of planning policies and services, which are increasingly less able to satisfy the new demands of contemporary cities for health and wellbeing. The ‘quality of space’ is connected not only with the physical and practical dimension of space but also to its ‘relational’ dimension between forms of life and environment and therefore to the use material and symbolic that people make of space. The intention is to employ a new focus on the forms of everyday life and practices in active citizenship involvement to intercept new needs and also independent social capacities to build well-being through processes of micro-change and the reinvention of people’s own living spaces. Public space, a clamorous example of urban hardship, is assumed as a privileged area for the deployment of such a perspective, by supporting capacities everyday, widespread, microscopic for ‘creating public space’ by society.
