Main issues, as the Inspector framed them

The effect of the proposed development on the character and appearance of the host building and the local area

What decided it

The proposed mansard roof extension would cause significant harm to the character and appearance of the conservation area and the host building by disrupting the established roofscape and architectural composition of the terrace, with no public benefits to outweigh this harm.

Plan policies cited: Policy CL1, Policy CL2, Policy CL3, Policy CL6, Policy CL8, Policy CL11
