Main issues, as the Inspector framed them
- Whether the proposal would preserve or enhance the character or appearance of the Arlington Square Conservation Area
What decided it
The full-width roof extension would cause less than substantial harm to the conservation area's character by introducing uncharacteristic built form above the undisturbed roofline of the terrace, and the limited public benefits do not outweigh this harm.
