Llanfair-fach House

Llanfair-fach House is a two-storey and attic house with an added house and kitchen wing, dating from the 17th century. The building is constructed of stone rubble with freestone dressings, now plastered and limewashed, and has a Welsh slate roof with stone chimneys. The main elevation faces south.

The south front features a large square chimney to the right and a central chimney. A two-storey gabled porch has a 2-light stone mullioned window on the first floor, with an ovolo mould and wide central fillet under a hoodmould. The ground floor of the porch contains a Tudor-arched entrance with voussoirs, and a main entrance doorway with an ovolo-moulded wooden frame and a 17th-century door with ovolo-moulded styles and long strap hinges. Diaper stone tiles pave the porch floor. To the right of the porch, the first floor has a 2-light stone mullioned window under a hoodmould, while the ground floor contains a 3-light mullioned window (replacing a 19th-century sash window) under a broad hoodmould; a small stair window is located to the right. To the left of the porch, a gabled dormer has a first-floor 2-light stone mullioned window under a hoodmould, and the ground floor features a 3-light mullioned window (replacing a 19th-century sash window) with a relieving arch. The right-hand gable has a projection housing the stair and chimney; a blocked first-floor window, originally intended to light the stairhead, is now a modern casement.

At the rear, a kitchen extension is set at a right angle, with a gable chimney. An outshut to the east has a small ovolo moulded window in the north wall. A catslide roof covers the pantry. To the left end of the main elevation is a small additional cottage, also two storeys high. This cottage has a central plank door flanked by casement windows, with two smaller windows above. All features on the cottage date from the 1990s, as do the small rooflights. The roof is plain, with a stack added to the existing house stack to the right. The rear elevation of the cottage has a plank door and a small casement on the ground floor, mirroring the front, and the upper floor is blind apart from a small rooflight.

A stone outbuilding to the north has reused medieval pointed arch (no longer visible following resurvey), suggesting a possible medieval house previously existed on the site.

The interior, inspected in 1995, features a cross-passage with a partition and central doorway to the hall. The ceiling is plastered and beams are boxed-in, although the condition may have changed since the 1995 inspection. Diaper stone tiles cover the floor. The parlour has an arched doorway to a former stair, now a cupboard, and has exposed beams, with the west beam having curved filleted stops. The rear wing has a wooden stair, roughly chamfered beams, square joists, and a separate pantry. Heavy roof trusses are visible through gaps in the slates. The west wing was reportedly converted to a separate dwelling in the 19th century, with two rooms to each floor. It has a cobbled floor, a fireplace, and stone stairs to the east wall.
