Main issues, as the Inspector framed them
- Whether the proposed development would preserve or enhance the character or appearance of the East Greenwich Conservation Area and whether the proposed development would protect the Outstanding Universal Value of the Maritime Greenwich World Heritage Site
What decided it
The proposed development's combined basement, rear and side extensions would disproportionately dominate No 18's existing modest form and undermine its notable contribution as the last remaining Victorian dwelling on the east side of Trafalgar Grove, causing moderate less than substantial harm to the conservation area and World Heritage Site setting that could not be justified by the modest public benefits offered.
