Serpentina is a pilot project for co-creation and urban transformation that sees play not only as children’s right, but as key to rethinking the city as a space for encounter, freedom and imagination. At the heart of the project is the rehabilitation of the Largo Soares dos Reis Playground, transformed into an intergenerational green park, where multiple uses interconnect naturally.
The proposal was developed by a multidisciplinary team coordinated by Maria João Macedo and Patrícia Costa. It was based on a participatory methodology involving the local community — residents, families and, above all, children — in diagnostic walks, workshops, assemblies and surveys. The results of these actions form the basis for the playground’s redevelopment project, which will be built by the municipality of Porto.
The project is part of a wider vision for a playful city, calling for a paradigm shift in how we understand the presence of children in public spaces and extending the study to the surrounding urban area. Specific interventions are proposed — such as the creation of “school streets,” the natural integration of playgrounds, or the conversion of streets into communal areas — which adopt principles of tactical urbanism. These proposals aim to create a more humane and inclusive city, in which the involvement of the local authority is fundamental.

Core Programme
Happisodes
Promoted by the Porto Design Biennale, Happisodes are co-design projects between designers, communities, and municipalities that bring to life, in Porto and Matosinhos, the joy of collectively recognising that the present can be reimagined. They are living, inhabited processes where design gives shape to the common.
Publications
Book publishing is a fundamental part of the Porto Design Bienniale, conveying, through the editing and materiality of the books and catalogues, the concept and curation of the projects.
Constellations
The selected projects are independent and autonomous projects regarding curation, financing and production that engage with the theme of this edition.
