Co-design of public spaces through design and art

The article describes solutions for public spaces, or those that are open to the public, to create scenarios forther use in the long termine a temporary and experimental way, which show a strong relationship between the worlds of design and art. Using a comparison of applied research experiences of the POLIMI DESIS Lab (PDL) research group (Design For Social Innovation and Sustainability) of the Politecnico di Milano, this article explores possible collaborations between designers, artists and critics and art curators for the redesign of portions of public spaces – or those that are open to the public – via co-planning actions and the involvement of educational activities in the design of spaces and services.The three cases presented differ in terms of relationships between the subjects involved and the impact of the result obtained:Arnold-Art and design in Nolo District (2017) in Milan; The Garden of Daniel Spoerri (2018) in Seggiano (GR); and Trentami in Verde (2019) in Milan. These cases present component systems that interact with each other to produce results that can improve a public space, or be used by an audience, in a temporary and experimental way to create scenarios for their use in the long term.
