This thesis has investigated the controversy surrounding Green Belt policy in England, reflecting on the relevant planning policies that define the use of land across England. This project has focused specifically on the impact of small-scale, minor residential developments in eroding Green Belt boundaries and the subsequent alteration in the use of land throughout England. The south-east county of Surrey and the district of Tandridge have been employed as unique case studies, in which the prevailing Green Belt trends and the predominant policy arguments employed in decision-making have been examined.
