Main issues, as the Inspector framed them

  • The effect of the proposal on the character and appearance of the host building
  • Whether it would preserve or enhance the character or appearance of the Castelnau Conservation Area

What decided it

The proposal would create an overly dominant roof form that harms the character and appearance of the host building and the conservation area, with no public benefits to justify the less than substantial harm to the heritage asset.
