The session aims to overcome the long-standing fragmentation between housing policy and spatial planning in Europe. Existing studies show that affordability crises, uneven development, and climate-adaptation pressures are structurally interlinked, yet governance systems still operate in silos. The emerging European Task Force on Affordable Housing offers an institutional window to reconnect these domains, but this requires shared instruments, comparable data, and new research capacities. The Netherlands—long recognised for integrated planning traditions, yet currently struggling with acute housing shortages—offers both cautionary lessons and strategic opportunities for European collaboration. The programme therefore brings established experts, practitioners, and young researchers together to explore how a cross-border, multi-scalar agenda can be shaped in practice.
