Main issues, as the Inspector framed them

  • The effect of the proposal on the host dwelling and whether the proposal would preserve or enhance the character or appearance of the Cole Park Road Conservation Area

What decided it

The extension's limited depth, single-storey scale, rear positioning, and replacement of an existing structure would preserve the visual gap between properties and the spatial hierarchy of the conservation area whilst maintaining the prominence of the host dwelling's key heritage features.
