The National Planning Policy Framework (NPPF) uses the term tranquillity for the first time in national planning policy. This can apply to relatively confined local areas as ‘Local Green Spaces’ or potentially more extensive ‘areas of tranquillity’ worthy of protection. However, the tranquillity of the countryside is likely to be under greater threat than before as a result of the development and growth policies in the NPPF. This briefing shows how to ensure tranquillity is included in your local plan.
