Main issues, as the Inspector framed them
- Whether the proposal would preserve the Grade II listed building of 18 and 20, Clifton Hill, or any features of special architectural or historic interest which it possesses

What decided it
The proposal would cause less than substantial but considerable harm to the special interest and significance of the listed building and the character and appearance of the conservation area, and the limited private benefits of adding a bedroom did not provide the clear and convincing justification required to outweigh this harm.
