Main issues, as the Inspector framed them

  • Whether the proposal would preserve or enhance the character or appearance of the Wimbledon West Conservation Area, including its effect on the host as a locally listed building

What decided it

The proposal would unduly harm the character and appearance of the host dwelling as a non-designated heritage asset and fail to preserve or enhance the character or appearance of the Wimbledon West Conservation Area, conflicting with the development plan and NPPF requirements for high quality design sympathetic to local character.
