Adaptive Reuse & Asset Activation

Turning Europe's underused buildings into homes — from conversion strategy to owner-side activation

Overview

Across Europe, the pressing need for affordable homes is colliding with rising vacancy rates in commercial and civic buildings. Rather than relying solely on new construction, cooperative housing movements are increasingly looking to adaptive reuse to transform existing structures into vibrant communities. This approach encompasses everything from converting post-pandemic office spaces and densifying retail rooftops to revitalising industrial brownfields and heritage sites. Making these transformations a reality requires a strategic pipeline that includes vacancy mapping, navigating complex regulatory pathways for change-of-use, and understanding the motivations of institutional and private asset owners. By structuring innovative deals, such as long-term leaseholds or joint ventures, cooperatives can unlock underused urban fabric and bring it back into common use.

Below, you will find resources exploring the mechanics and potential of these conversion strategies. The knowledge section features recent studies quantifying office-to-living potential in cities like Munich, Basel, and Brussels, alongside municipal action plans from Glasgow and Edinburgh aimed at activating empty homes. You can also discover organisations driving this change, ranging from architectural practices like Assemble to dedicated agencies such as Agentur StadtWohnen Chemnitz and AHA Budapest. Featured projects highlight concrete examples of this work, including office conversions in Boulogne-Billancourt and the redevelopment of former military sites. Finally, a listing of upcoming events, such as the Urban Future Festival and symposiums on commoning spaces, invites you to connect with practitioners rethinking the built fabric for the common good.
