Main issues, as the Inspector framed them

  • The effect of the proposed development on the character and appearance of the Dartmouth Park Conservation Area

What decided it

The proposed mansard roof extension would cause less than substantial harm to the character and appearance of the Dartmouth Park Conservation Area by introducing an isolated and incongruous addition to a street characterised by consistent roof forms, and this harm is not outweighed by any public benefits.
