Synopsis

How do we foster trust in our public spaces, communities, and each other? Trustmaking explores how the youth can lead the way in reimagining cities through collaboration and creativity. This book introduces trustmaking as an approach to inter-generational co-creation, grounded in principles that transcend conventional urban-planning paradigms. Featuring insights from four European Urban Living Labs, this guide offers strategies - such as arts-based interventions and placemaking - that empower young people to co-create inclusive, trust-filled urban futures.

For planners and policymakers, and anyone invested in inclusive cities, Trustmaking offers fresh perspectives and actionable, co-creative tools to bridge generational gaps, foster collaboration, and rethink the role of trust in a post-pandemic world.
