The document outlines the 'Tamalaca Tuttamialacitta’' project focused on participatory planning in Sassari, emphasizing urban rights and the quality of life for children in marginalized urban areas. The project aims to transform derelict spaces through children's input, fostering community engagement and collaborative design, exemplified by the successful 'Portacolori' initiative, which revitalized a school playground. Future efforts will extend beyond school boundaries to further integrate community and educational spaces.
