Main issues, as the Inspector framed them

  • The effect of the proposed development on the character and appearance of the site with special attention paid to the desirability of preserving or enhancing the character or appearance of the Osterley Park Conservation Area

What decided it

The proposed extension would visually disrupt the original proportions and symmetry of the host dwelling and its pair, detracting from aesthetic features that contribute to the conservation area's significance, with no public benefits to outweigh this less than substantial harm.
