Across Europe, the push for affordable housing increasingly intersects with the need to decarbonise the built environment. Adaptive reuse and asset activation offer a strategic pathway to transform underused structures into cooperative homes, encompassing everything from converting obsolete office blocks and adding residential layers above retail parks, to regenerating industrial brownfields. Aligning with frameworks like the European Affordable Housing Plan, this approach treats existing buildings as vital resources rather than liabilities. Making these conversions viable requires a robust owner-side activation pipeline. Practitioners must map urban vacancy, navigate complex change-of-use regulations, understand the motivations of institutional asset owners, and structure innovative deals such as long-term leaseholds or joint ventures to secure spaces for community-led living.
Below, you will find a curated collection of resources, organisations, and case studies dedicated to repurposing empty spaces. The knowledge section features practical insights into office-to-residential conversions, tools for tackling vacant housing, and research on building sufficiency. You can explore the work of pioneering organisations such as Assemble, Concular, and Don't Waste Buildings, alongside established bodies like the Austrian GBV. The project directory highlights successful examples of adaptive reuse, including the Hunziker Areal development and Bajesdorp, demonstrating how cooperative models revitalise urban spaces. Finally, the events listings connect you with upcoming gatherings, from the Adaptable Building Conference to the Urban Future Festival, inviting you to engage with practitioners turning obsolete properties into thriving homes.
