Main issues, as the Inspector framed them
- The effect of the development on the character and appearance of the area, including the preservation or enhancement of Harefield Conservation Area
- The effect of the rear single storey extension on the living conditions of the occupants of 59 Newdigate Road having regard to outlook and light
What decided it
The roof alterations and dormer cause less than substantial harm to the Conservation Area that cannot be justified by the limited public benefit of increased accommodation, whereas the single storey rear extension is acceptable as it is subordinate, not visible from public views, and does not harm neighbour amenity.
