Main issues, as the Inspector framed them

  • The effect of the proposed development on the character and appearance of the host dwelling and the surrounding area, including whether it would preserve or enhance the character or appearance of the Harlington Village Conservation Area

What decided it

The excessive scale and bulk of the proposed roof works, combined with the loss of characteristic chimneys, would cause less than substantial but considerable harm to the Harlington Village Conservation Area that cannot be justified by the private residential benefits of the scheme.
