It took Anton Jones 15 years to buy what was known locally as Llantwit Castle from the Vale of Glamorgan council and another five years to transform the medieval house.
No cranes or cement mixers were used and all the materials were mixed and constructed using traditional methods.
Lime mortar was used and the solid oak beams were cut and constructed on site.
Anton was fascinated with the building since he was a child where he used to play but was also “scared to death of it.”
He said: “It was very, very creepy in those days because the ruin was totally covered in ivy.
“It was always very gloomy even on a summer’s day and there was always an eerie presence here and I actually got chased by horses here once.
“I can still hear the hooves hitting the stones now when I’m working here.”
When he bought the property for £5,000 the “conservation builder” feared he had bitten off more than he could chew when the extent of the restoration project became fully clear.
Anton said: It was completely ruined, in fact it shouldn’t really have been saved because it was too far gone.
It looks nice.
Unfortunately, it is in Britain.
