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 proposals would fail to preserve the special architectural and historic interest of the Grade II listed building, and the identified less than substantial harm to the heritage asset is not outweighed by the limited public benefits of the scheme.
