THEY say that every man’s home is his castle, but what if that home also comes with its own Iron Age hill fort?

The 19th century Nant-Y-Coy Mill, in Treffgarne, has been put on the market, and comes with around thirty acres of grounds, a quarter of a mile of salmon river, and a 14-foot water wheel.

The property – which agents Country Living Group describe as providing a “fantastic lifestyle opportunity with huge income potential” – has been listed for sale for £1.35 million.

The mill house offers a myriad of interesting features.

Along with its five bedrooms and one-bedroom annexe, there's a slate-floored reception room from where an archway opens out into the kitchen which runs the length of the building.

The living room comes with original slate flag flooring with exposed beams and contains the original workings of the water wheel, with a home bar created adjoining.

To the back of the main house is a rear garden cut into the rockface which houses a pizza oven and outdoor dining area.

Along the path heading from the main house to the ancient woodland is a charming, elevated, summer house, which provides another wonderful entertaining space with a hot tub, dining area, and power connection.

The grounds also feature a former café, which could also provide additional letting accommodation and be converted in to two one-bedroom units or a larger three-bedroom property, subject to planning.

The property includes four paddocks which have been the base for a successful glamping business run by the owners. This has permission for ten pitches, with an option for five more.

“It offers huge scope for a buyer to develop their own lifestyle and business,” a Country Living Group spokesperson said.

On the opposite side of the road from Nant-Y-Coy, the property also owns the meadow and around a quarter of a mile of the Western Cleddau, including fishing rights. This stretch of water also includes an island, accessed via a footbridge, which is the perfect spot for anglers or those who just want to take in nature.

The owners have planted numerous trees around the estate including fifty gala apple trees in the meadows.
