Main issues, as the Inspector framed them

  • Whether the proposed development would preserve or enhance the character or appearance of the Gunnersbury Park Conservation Area

What decided it

The hip to gable roof conversion would harm the character and appearance of the Gunnersbury Park Conservation Area by appearing more prominent than existing examples and failing to preserve the established hipped roof character of the street scene, with no public benefits identified to outweigh this harm.
