Llwynywermod, (Welsh: Llwynywermwd), also known as Llwynywormwood, is an estate owned by the Duchy of Cornwall, in the Brecon Beacons National Park in Wales.
The 192-acre (0.78 km2) estate is near the village of Myddfai, Llandovery, Carmarthenshire; the Duchy completed its purchase of the property in March 2007. The three-bedroom farmhouse was converted into a residence for Charles, Prince of Wales, who is also the Duke of Cornwall, by Craig Hamilton Architects[1] using traditional building techniques.[2] It was once the coach house to the now ruined 13-bedroom country house of the Griffies-Williams family that stood nearby.
Charles and Camilla, Duchess of Cornwall, took up residence at the property in June 2008.[3]
The courtyard range adjoining the main house is let as holiday accommodation when the Prince is not in residence.[4]
The historian Mark Baker has written a book detailing the history of the estate and restoration, entitled A Royal Home in Wales: Llwynywermod.[5] It was originally commissioned by the Welsh Historic Gardens Trust, who presented a special leather-bound copy to the Prince of Wales in February 2008.
