Main issues, as the Inspector framed them

  • The effect of the development on the character and appearance of the host property, and whether the development preserves or enhances the character or appearance of the Gunnersbury Park Conservation Area

What decided it

The proposed dormer's scale, position and appearance would harm the character and appearance of the host property and fail to preserve or enhance the Gunnersbury Park Conservation Area, and the modest public benefits could not outweigh the great weight required to be given to conservation of the designated heritage asset.
