Main issues, as the Inspector framed them
- Whether the proposed development would preserve or enhance the character or appearance of the Highgate Conservation Area
What decided it
The proposed extension would erode the established symmetry and consistent architectural rhythm of the Victorian terrace's rear outriggers, causing less than substantial harm to the Highgate Conservation Area that cannot be outweighed by the limited public benefits.
