Trefnant Hall

The entrance hall, in the E bay, has dado panelling and a plasterwork Doric triglyph frieze with guttae around 3 sides. It contains a remarkable early-mid C18 dog-leg stair, with triple turned balusters to each tread and wreathed handrail with spiral finish. The treads have foliage carved brackets, and are inlaid with a 'barber's pole' band of bog oak and contrasting holly, with a central pagoda-like feature. The hall enters directly into the large but plain ceiled drawing room, with 3 fielded and six panelled doors, and an axial fireplace. An enfilade door leads directly to the parlour, which has two chamfered spine beams and an arch-headed and dentilled doorcase, now blocked, originally opening to the small secondary hall at the W end. This room has a fine C18 chimneypiece having pilasters with a strongly tapered lower section, and a dentilled cornice, surrounding a very fine mid C17 carved oak overmantel of 2 arched panels with floral carvings, and at the head, confronting grostesqe beasts. Opposite, a round headed double door opening with dentilled cornice formerly opened into the small western end hallway. The added rear range contains the kitchen with a huge fireplace, behind which is a service room and a secondary stair. Doors are 2-slightly fielded panels, probably early C18. The roof is of 4 bays; heavy framed collar trusses, raking struts and straight windbraces to 2 tiers of purlins, and with one arched doorhead, apparently surviving from the C17 house. The rear wing roofs are of similar construction, indicating that they may be of the same date as the front roof.

The C18 exterior is built of local stone rubble with a slate roof. Probably originally of four window bays either side of a central entrance. The remaining house is of two storeys, 5 window bays, with the main entrance now at the extreme right (E) bay; a margin-glazed door in an eared architraved frame with pulvinating frieze and steep pediment. Above, the stair hall is lit by a Venetian pattern window set in a fluted stone surround and keyed arch over the centre 15-pane sash window. The rest of the front has flush-framed 12-paned sashes (renewed) set under voussoired flat arches of local stone, those of bays 2 and 3 originally extending to ground level. Over bays 3 and 4 there is a jettied raised gable of rendered timber framing on brackets, with deeply protruding eaves and small attic window. A low outbuilding, probably of the C19, is added to the E gable. To the rear, there is a substantial 2-storey wing, which was probably added soon after the original construction, terminating in 3 gables facing N. Blind relieving arches of brick in the gable indicate possible later alterations but may be decorative. A Venetian window identical to that at the front is placed at the rear of the E hall bay. Brick lean-to in angle.
