Main issues, as the Inspector framed them

The effect of the proposal upon the character and appearance of the appeal property and the wider area, including the Duncan Terrace/Colebrooke Row Conservation Area

What decided it

The proposed dormer would fail to preserve or enhance the character and appearance of the conservation area, contrary to the statutory duty under section 72(1) of the Planning (Listed Buildings and Conservation Areas) Act 1990 and development plan policies, with no public benefits identified to justify the harm.
