Main issues, as the Inspector framed them

  • Whether the proposal would preserve a Grade II* listed building, 12-21 Clapham Common North Side SW4, or its setting or any features of special architectural or historic interest which it possesses
  • Whether the proposal would harm the health of and/or prejudice the retention of trees on the site
  • Whether the proposal would preserve or enhance the character or appearance of the Clapham Conservation Area

What decided it

The proposed glasshouse/conservatory would harm the special interest and significance of the Grade II* listed building and its setting through its size, proximity, siting and incongruity, and the lowering of ground levels would alter the building's relationship with its curtilage, with the identified heritage benefits insufficient to outweigh this harm.
