Main issues, as the Inspector framed them

Whether the proposals would preserve the listed building or any features of special architectural or historic interest which it possesses and, linked to that, whether the proposal would preserve or enhance the character or appearance of the conservation area

What decided it

The less than substantial harm to the significance of the Grade II listed building and conservation area, when weighed against the limited public benefits of the scheme, did not justify the grant of planning permission or listed building consent.

The less than substantial harm to the significance of the designated heritage assets was weighed against the public benefits of the scheme including economic benefits and creation of a third bedroom; the harm outweighed the benefits and the statutory presumptions in favour of conservation were not displaced.
