T-Factor is a Horizon 2020 project that seeks to unlock the transformative potential of temporary use in urban regeneration. We gather together cities, universities, businesses and grassroots organisations committed to creating new knowledge, tools and approaches to temporary urbanism that can contribute to inclusive and thriving futures in cities. We work across advanced and early stage regeneration initiatives in Europe and beyond, leveraging international collaboration to advance strategic policy-making, research and innovative practice in this emerging field.
