In 1919 Col. William Nathaniel Jones of Dyffryn, Ammanford bought the Estate from Major Hughes, the son of Adah Abadam who was the daughter of Edward Hamlin Adams.
An industrialist, Col. Jones was granted his military title when he was put in charge of the Ammanford Home Guard during the First World War. Jones never lived at Middleton Hall. He put in place a caretaker, Mr Hilbert Lloyd, and his family who farmed pigs, while the rest of the land was tenanted.
But then disaster struck “a fine old country mansion….was reduced to ruins by fire” (Carmarthen Journal, November 6th, 1931). The property was mortgaged and in 1934 Carmarthenshire County Council bought the “mansion house, park lands, messuages, tenements and all buildings thereon, lands covered with water and other hereditaments known as The Middleton Hall Estate” from Barclay’s Bank for £7,500.
The County Council converted the outbuildings, including the servants’ block which was the only element of the mansion house to survive the fire, and built new farmsteads to create seven individual starter farms to encourage young people to enter the agricultural industry. The estate became a thriving community which continued through to the 1990s.
Waun Las Farm was built by Carmarthenshire County Council in the mid 1930s.
