Yes, and with less argument than a village this well-heeled usually allows. No conservation area covers Feock. Two dozen buildings carry a listing, and everything else carries none. The neighbours are putting applications in by the hundred. The obstacle here is not the planning department, it is what the miners left under the fields.
Historic England's register records 24 listed buildings in the area: three at Grade II star and 21 at Grade II, with none at Grade I. Listing protects the whole building, inside as well as out, and usually takes in walls, outbuildings and anything else attached to it. Owning one means listed building consent on top of planning permission for changes that affect its character, which covers a great deal more than people expect: windows, internal walls, a flue, sometimes the colour of the render. For the other several hundred homes in the parish, none of that applies. The register is a small club and most of the village is not in it.
There is also one scheduled monument in the area, which sits at the strictest protection tier of the lot. Scheduled monument consent comes from national government rather than the council, and it bites on the land around the monument as much as on the thing itself. Unless you are buying a plot next to it, this is context rather than an obstacle.
The live evidence is the best answer to the question. The planning record carries 718 applications across the area between April 2024 and June 2026, with 321 of those in the last twelve months. That is not a place where nothing gets built. Outcomes are not consistently recorded, so nobody should quote an approval rate at you, including this page, but the volume alone tells you that extending, converting and reroofing is routine local behaviour rather than a fight.
The ground is the part that catches people out. Cornwall's mining legacy shows up here: about 41% of the area's postcodes have a recorded abandoned mine nearby, with the closest at roughly 265 metres. None sit directly over a recorded working. In practice this means a mining search during conveyancing and, on some plots, a specialist report before anyone digs foundations. It is a paperwork and survey issue rather than a safety verdict, but lenders and insurers do ask, and finding out at the footings stage costs considerably more than finding out at the search stage.
So the practical position is straightforward. If your house is not listed, ordinary permitted development rights apply and a single-storey rear extension or a loft conversion is the sort of thing the council sees constantly. If it is listed, budget for a heritage statement, an architect who has done it before, and a longer timetable. Either way, the ground investigation is the line item people forget and then wish they had not.
Freedom to alter a home is one of the better things about buying here: no conservation area, a short list of protected buildings, and a planning record that shows the work going ahead.
