House & Family History: The original 13-bedroom country house of the Griffies-Williams family is a today a ruin. The 192-acre Llwynywermod Estate, situated in the Brecon Beacons National Park, was purchased for Charles, The Prince of Wales, in 2006 by the Duchy of Cornwall. Prince Charles engaged Craig Hamilton Architects to convert the former three-bedroom farmhouse (originally the coach house) into his Welsh seat. The architects converted the farmhouse into a modern home using traditional building techniques and the prince and the Duchess of Cornwall took up residence in June of 2008. As part of the conversion, the adjoining courtyard range was renovated and designed to be let as holiday accommodation when the royal family is not in residence. In 2008 the historian Mark Baker published "A Royal Home in Wales: Llwynywermod," a book detailing the history of the estate and its restoration.
