Main issues, as the Inspector framed them

  • The effect of the proposal on the character and appearance of the host property and the area, including whether it would preserve or enhance the character or appearance of the Sunray Estate Conservation Area

What decided it

The extension's considerable height, scale and footprint would create an awkward and overbearing appearance visible from neighbouring properties and the public realm, failing to be suitably subordinate to the host and thereby harming the character and appearance of the conservation area, with insufficient public benefits to outweigh this harm.
