Hoare Jenkins was a High Sheriff of Glamorgan who was involved in the suppression of the Merthyr Rising of 1831 and is recorded as stating that he found the execution of Dic Penderyn the most difficult of his civic duties.

Around 1800 some major improvements were made to the house with the addition of a three-storey circular stair hall which includes a dramatic geometrical staircase.

Following his death in 1915 Colonel Blandy-Jenkins's wife kept the house until 1953, after which it was bought by Sir George Williams CBE MC,[4] a descendant of Oliver Cromwell,[5] of the Williams family of Aberpergwm House and St Donat's Castle and his wife Grizzle a descendent of Thomas Cochrane, 10th Earl of Dundonald.

The house has been used regularly for filming for programmes such as Sherlock, Upstairs Downstairs, Doctor Who and Pobol y Cwm.

Actors including Sir Alan Bates, Ruth Negga and Ed Stoppard have all performed at the house.
