Main issues, as the Inspector framed them

  • Whether the proposed development would preserve or enhance the character or appearance of the Harpenden Conservation Area, including its effect on the significance of the appeal dwelling as a non-designated heritage asset

What decided it

The scale, mass and design of the proposed dormers would harm the significance of the non-designated heritage asset and fail to preserve or enhance the character and appearance of the conservation area, with no public benefits sufficient to outweigh this harm.
