Blaenddol House

Blaenddol House is a Grade II* listed building, primarily two storeys high with a cellar, featuring a central rear wing that houses the staircase. A curved flight of slate steps leads up to a terrace next to the central entrance, which is sheltered by a later hipped-roof porch. On either side of the doorway are three-light casement windows with splayed stone lintels, and there are three similar windows above. The house has a stack on the rear wing, which originates from the fireplace in the right-hand unit, and another stack on the left-hand gable. The early 18th-century wing projects to the left and is built on a full-height basement storey. Its gable end has paired blocked windows on the high ground floor and first floor, along with doorways on the return elevation, featuring decorated slate inscribed with the date and initials R over G.M. A large lateral chimney is tied back to the main roof line by a gablet.

To the west of the house are former farm buildings, with the earliest structure immediately adjacent. This building has a doorway at the angle with the west wing of the house, and adjoining it is a somewhat later building with a doorway to the right and paired windows. Further along is an even later building that features two doorways and small windows at varying heights. The earliest building is internally divided into two bays by a central truss, which appears to have been partially altered in the roof line. It has queen posts above the tie beam and a broad king post above the collar. The remains of a panelled partition wall below the truss and a chamfered and stopped spine beam in the lower unit suggest earlier domestic use. The roofs of the other buildings feature queen struts.

Inside the main range, there are two rooms with a central entrance and stair hall. The right-hand room includes a rear wall stack and chamfered and stopped joists along with a transverse beam. The left-hand room also has a similar beam and an end wall fireplace that contains a mid-19th-century cast iron range. Most internal partition walls are timber framed, and the roof is divided into three bays by A-frame collar trusses. The principal room of the west wing boasts a fine plaster ceiling, which is divided by a central beam into two panels, each featuring central and corner roundels adorned with low relief rosettes, birds, suns, or pendant stars.
