Trefecca Fawr

Trefecca Fawr is a large farmhouse dating back to the 17th century, built of rubble sandstone with a hipped tiled roof. The original house comprised a two-bay hall and kitchen arranged east to west. Between approximately 1675 and 1700, a two-bay cross wing was added to the west end, likely replacing a parlour bay and creating what are now the great and small parlours. A further extension to the north of the kitchen, added after approximately 1700, created a more symmetrical north elevation. A 19th-century service building, with its own separate roof, is attached to the east side of this northern addition.

The central hall has a low, nail-studded door with a segmental head, which may have been inserted after 1700. Above the doorway is a mantled crest bearing the arms of the Gwynne family, displaying 20 quarterings. Either side of the door are ovolo-moulded transomed four-light windows, and three-light symmetrical windows illuminate the upper floor. The parlour wing, constructed shortly after the main hall, features two-light transomed windows with thrice-rebated timber lintels, the soffits painted red. On the north front is a transomed stair window and a matching window to the great parlour. The kitchen wing extension has three transomed windows on two floors. Two chimney stacks are situated on the west side of the parlour wing. The east elevation, enclosed within a small courtyard, exhibits a four-light ovolo-moulded window to the kitchen, with a similar window on the south elevation, now replaced with a 20th-century oak window.

Facing the main north front is the Scheduled Ancient Monument No. B87, likely the remains of landscaped formal gardens and canals, possibly converted from earlier fishponds.

The main hall has a stone flagged floor and fully fielded, moulded panelling, divided by sharply tapered Ionic pilasters, with the panelling incorporating a bolection moulded chimneypiece and tongue-and-leaf moulding. Part of the original cornice remains. The plaster ceiling features a central rosette within a wreath, set within a square and a larger roundel, containing sparse foliage and detached fruits. Similar foliage sprays are enclosed in shaped panels formed by harvest wreaths at each corner.

Beyond a small room is the great parlour, which is also panelled and boasts an unusually fine coffered plaster ceiling dating from approximately 1680 to 1690. The ceiling ribs are enriched with luxuriant harvest motifs, and each compartment contains a garland surrounding sparse foliage sprays. The wall panelling includes recessed panels designed to hold stretched fabric. An adjoining small chamber, which now incorporates a former passageway to a side door, contains recessed oak shelving and a simple moulded central cross ceiling panel. A fireplace is located in the northwest corner of the room. The dog-leg framed oak staircase, also from the 17th century, extends to attic level, featuring panelled square newels with ogee caps, robustly turned balusters, and a heavy moulded handrail.
