Under the motto "Time is Present. Inventing the Common", the 4th edition of the Porto Design Biennale brings us new perspectives on qualitative time and the collective ability to shape the present. The programme, curated by Angela Rui, proposes the active involvement of design in the materiality of the present time and in the experience of community dynamics. Working with communities and associations in Porto and Matosinhos, this edition of the Biennale seeks to promote joint creation practices and be a platform to support local projects.
