the authors of "carmarthenshire and ceredigion" consider the heavily decorated late 17th-century ceilings of the house to be "the finest single architectural legacy among the country houses of the region". as in plas taliaris and several other country houses in the county, the ceilings are panelled, with "thick moulded beams and wreaths in the panels and winged cherubs' heads in the corners". the entrance hall contains a columned doric screen with a 19th-century ribbed and bossed ceiling. the old dining room to the right of this features a coffered ceiling dated to the 17th century, containing "low plaster relief mouldings including guilloché, acanthus and egg and dart". the chimney piece has been removed. the drawing room to rear of the property also features a richly adorned coffered ceiling with "frieze bearing rosette bands" and a "centre oval with bay leaf design". the 17th-century staircase features thick balusters and prominent finials, with foliage patterns ingrained in the plasterwork of the handrail. a billiard room was added to the house in 1896. a strongroom with walls and heavy steel fire-proof doors was added in 1914, for the dynevors to keep their important documents and valuables. on the upper floors are rooms with 18th-century fittings, including "panelled dados, lugged architraves, low relief plaster ceilings and closets within angled turrets". the bedroom on the northeast of the house features a particularly detailed coffered ceiling with floral patterns.
