Hack the city: Designing inclusive, smart and nature-Integrated urban environments together.
Cities today face intersecting challenges: climate pressure, social fragmentation, car-dominated infrastructure, data overload, and widening inequalities in access to high-quality public space. Streets, squares and transit hubs are too often designed for speed, consumption and traffic efficiency rather than for wellbeing, connection and ecological resilience.
The Widening Hackathon: Crafting Future Cities responds to these challenges by creating a structured space for experimentation, collaboration and applied innovation.
Organised under the UNITE! Widening framework by Wrocław University of Science and Technology, Universidade de Lisboa, and KTH Royal Institute of Technology,
This 48-hour hybrid innovation challenge brings together students, researchers, professionals and engaged citizens to rethink public space as a living, shared and regenerative commons.
We are creating a Europe-wide platform to turn urban challenges into actionable solutions. Over two days, multidisciplinary teams tackle real issues – mobility, climate adaptation, public health, circular infrastructure, and digital inclusion using human-centred, data-driven approaches. Teams prototype ideas that are feasible, scalable, and socially equitable, factoring in finance, governance, and environmental impact. By showcasing solutions through engaging storytelling and compelling pitches, ideas gain momentum, attract collaborators, and spark real change. Our mission is to transform innovation into impact – making Europe’s cities smarter, fairer, and ready to meet the challenges of tomorrow.
