Why it was refused

The proposed development, by virtue of the dwelling being a replacement dwelling and the resultant floorspace uplift from the original building, its size, bulk, width and depth would result in a disproportionate addition over and above the size of the original building. The development would therefore constitute inappropriate development, which is, by definition, harmful to the Green Belt. The proposal would also result in limited harm to the openness of the Green Belt. No very special circumstances have been demonstrated which would clearly outweigh the inherent harm to the Green Belt or any other identified harms. The development therefore fails to accord with policy P2 of the Guildford Borough Local Plan: Strategy and Sites (adopted by Council on 25 April 2019) and Chapter 13 of the National Planning Policy Framework 2024
The proposed rear dormer window, by virtue of its substantial width and considerable depth, would not respect the scale and proportions of the existing dwelling, appearing an overly dominant, bulky and incongruous addition to the roof slope, to the detriment of the form, scale and character of the existing dwelling. The proposal would therefore fail to comply with policies D1 of the Local Plan: Strategy and Sites 2015, D4 and H4 of the Local Plan: Development Management Policies 2023, EH-H7 of the East Horsley Neighbourhood Plan, the Residential Extensions and Alterations SPD 2018, and the National Planning Policy Framework 2024.
