Public spaces are always the result of continuous coexistence and negotiation, especially in densely populated urban areas, where different people experience them in different ways, according to different times, activities, interests, values and meanings. They are therefore not stable or uniform places, but realities in constant flux, heterogeneous and subject to negotiation. It is precisely there that the social interactions and everyday experiences of urban life take place. 

A public space cannot exist without a shared sense of belonging and an urban culture resulting from the confrontation between all those who inhabit and pass through it. Designers can play a role as facilitators of processes of spatial and social regeneration of public spaces, rooted in bottom-up participatory processes.
