Inspector: Owen Woodwards
Postcode: TN15 0QZ

Main issues, as the Inspector framed them

whether or not the proposal preserves the Grade II listed building 'Old Allens' or any features of special architectural or historic interest which it possesses
whether or not the proposal preserves the Grade II listed The Barn or any features of special architectural or historic interest which it possesses in terms of how the building is experienced in its setting
whether or not the proposal would preserve or enhance the character or appearance of the Conservation Area

What decided it

The loss of legibility of the inter-war extension's plan form as a subservient area, combined with loss of important historic fabric and poor design of the rear extension, resulted in less than substantial harm to the listed building which outweighed the limited private benefits of improved internal layout.
