Main issues, as the Inspector framed them
- Whether the proposal would preserve the special architectural and historic interest of The Sussex Barn, a curtilage listed building, and the setting of Thistleworth Farm, a Grade II listed building
What decided it
The extensions would cause less than substantial harm to the significance of the curtilage listed barn and the setting of the Grade II listed farmhouse, and the public benefits of the scheme do not outweigh this harm.
The public benefits of providing an additional home and securing the barn's long-term maintenance were outweighed by the less than substantial harm to the significance of the designated heritage assets.
