Main issues, as the Inspector framed them
- The effect of the proposed development on the architectural integrity of this Locally Listed property and thereby whether it would serve to preserve or enhance the character or appearance of the St Albans Conservation Area
- The effect of the proposal on the living conditions of neighbouring residential occupiers in terms of potential of the proposal to appear overbearing and result in a loss of outlook
What decided it
The proposed dormer's non-traditional materials (fibreglass roof and Cedral cladding) would compromise the architectural integrity of the locally listed building and harm the character and appearance of the conservation area, with public benefits insufficient to outweigh this harm.
