Main issues, as the Inspector framed them
- Whether the proposal would preserve or enhance the character or appearance of the host building and the Maida Vale Conservation Area
What decided it
The harm to the conservation area, albeit small, must be given great weight and cannot be outweighed by the private benefit of additional living space to the occupier.
The less than substantial harm to the conservation area was weighed against the private benefits of additional living space, which are not public benefits; the harm outweighed the benefits.
