Unlocking Sustainable Development Opportunities in the Green Belt
In December 2024, the revised National Planning Policy Framework (NPPF) introduced the concept of grey belt land, a transformative shift in UK planning policy. This new designation has opened the door to sustainable development within the Green Belt, offering a unique opportunity for housebuilders, developers, investors, landowners, and local authorities to address the housing crisis while preserving the best parts of the Green Belt. At Marrons, we’ve analysed the first year of grey belt implementation and compiled a comprehensive report that explores its impact.
What’s Inside the Report?
