Main issues, as the Inspector framed them
- whether the proposal would preserve the Grade II listed building or its setting, or any features of special architectural or historic interest which it possesses
- whether the proposal would preserve or enhance the character or appearance of the Duncan Terrace/Colebrook Row Conservation Area
What decided it
The absence of any significant public benefit to outweigh the less than substantial harm to the significance of the Grade II listed building meant the proposals could not be convincingly justified.
less than substantial harm to the significance of the listed building was not outweighed by any public benefits, as the works represented private aspiration rather than securing the building's optimum viable use or conservation
