Main issues, as the Inspector framed them

  • Whether the proposed development would preserve or enhance the character or appearance of the Harley Street Conservation Area, and whether it would preserve the setting of the Grade II listed building at 1-6 Upper Wimpole Street

What decided it

The proposed contemporary aluminium-framed windows would cause less than substantial harm to the character and appearance of the Harley Street Conservation Area and the setting of the Grade II listed building, with no public benefits sufficient to outweigh this harm.

Plan policies cited: Policy 38, Policy 39, Policy 40
