Trefecca Fawr

Main hall has a stone flagged floor and fully fielded moulded panelling divided by sharply tapered Ionic pilasters, the panelling eared over the bolection moulded chimneypiece, enriched with tongue-and-leaf moulding. Cornice partly survives. Plaster ceiling, comprising a central rosette within a wreath, within a square, set in a large roundel, containing sparse foliage sprays with detached fruits. Each angle of the room has similar foliage sprays enclosed in shaped panels formed by harvest wreaths.

Beyond a small room, the great parlour, also panelled, has an unusually fine coffered plaster ceiling of 1680-90, the ribs enriched with luxuriant harvest motifs, each of the compartments containing a garland enclosing similar curiously sparse foliage sprays. Wall panelling, the panels above the dado recessed to take stretched fabric. The small chamber adjoining now incorporating a former passage to a side door, has recessed oak shelving and a simple ceiling comprising a moulded central cross panel. A fireplace is contained in the NW angle of the room. Adjoining, in the N wing, is the dog-leg framed oak stair, also C17 and extending to attic level, comprising panelled square newels with ogee caps, and robustly turned balusters supporting a heavy moulded handrail.

Rubble sandstone with hipped tiled roof. Two storeys. The form of the original house consists of a 2-bay hall and kitchen set E-W, to which is added c1675-1700 a 2-bay cross wing at the W end, perhaps replacing a parlour bay, providing the great and small parlours. Central main hall has an axial stack backing on to the kitchen, which has an extension to the N added after c1700 forming an approximately symmetrical N elevation. A C19 service building, separately roofed, is attached to the E side of this addition.

Central low nail-studded door with segmental head to hall, perhaps inserted post-1700 to replace a lobby entry. Above a mantled and crested arms of Gwynne family, with 20 quarterings. Either side, ovolo-moulded transomed 4-light windows, and 3 light symmetrical windows to upper floor. Parlour wing, built shortly after the main hall range has 2-light transomed windows, with thrice-rebated timber lintels, the soffits painted red. On the N front transomed stair window and a similar window to the great parlour. The added kitchen wing has 3 transomed windows on 2 floors. Two stacks to W side of parlour wing. E elevation, enclosed in small courtyard, has a 4-light ovolo moulded window to the kitchen, and a similar window to the S elevation, replaced with a C20 oak window.

Opposite the main N front is the Scheduled Ancient Monument No B87, probably the remains of landscaped formal gardens and canals, perhaps converted from earlier fishponds.
