Main issues, as the Inspector framed them
- Whether the proposal would be inappropriate development in the Green Belt and, if so, the effect on the openness and purposes of the Green Belt
- Whether the proposal would preserve a Grade II listed building, 'Trench Farmhouse', and any features of special architectural or historic interest it possesses
- Whether the proposal would preserve or enhance the character or appearance of the Coldharbour – Hildenborough Conservation Area
- Whether any harm by reason of inappropriateness, and any other harm, would be clearly outweighed by other considerations, so as to amount to the very special circumstances required to justify the proposal
What decided it
The cumulative effect of the proposed extension combined with the existing substantial rear extension would amount to disproportionate additions to the original dwelling in the Green Belt, and would fail to preserve the special interest of the listed building and character of the Conservation Area, with no public benefits to outweigh the identified harms.
