Housing in many European countries has become unaffordable for many. In fact, it is now considered to be one of the most important national issues in Europe and its solution is proving very challenging. Providing affordable and sustainable housing is a complex task involving multiple disciplines, sectors and actors and requires transdisciplinary research.The EU-funded RE-DWELL project will train 15 early-stage researchers (ESRs) in design planning and building, community participation, and policy and financing, providing them with the capacity to operate across fields and sectors, generating innovative solutions for the housing problem in the EU.
