This large detatched house in Regency style was built in the early-mid C19. Forming part of The Lawn, which was a large wooded enclosure of about 20 acres containing 3 large houses built for the Rhymney Iron Company, consolidated 1837; one traditionally used by the Directors, one by the Manager and one by the Surgeon. This building was converted in 1924 to a school and was one of the first in the country to provide a joint grammar/secondary education, a pioneer of the later comprehensive system.
Although converted to a school, the interior retains its plan of a central corridor with rooms leading off and to rear a staircase which has turned newel posts, stick balusters and a ramped handrail. Some rooms retain plaster cornice mouldings, moulded plaster panels and brackets, 6-panelled doors with architraves, panelled reveals and shutters.
It was listed notwithstanding alterations as one of a group of 3 important residential buildings associated with the Rhymney Iron Company.
