Planning appeal 3368052 at 2 Rookery Cottages Mile Hill, Porthtowan, Truro, TR4 8TY (Cornwall Council) was allowed on 20 October 2025 by Inspector Davies N, by written representations.

Main issues, as the Inspector framed them
- Whether the site is suitable for a new dwelling, bearing in mind the settlement policies of the development plan, and if not, whether the structure could reasonably operate as an annexe to the main dwelling, and whether such occupation would overcome any policy conflict or other harm
What decided it
The structure, although self-contained in facilities, could reasonably operate as an annexe ancillary to the main dwelling based on the intended use and functional interdependence, thereby avoiding conflict with settlement policies while reducing vehicle dependency compared to an independent dwelling.
