Bach-y-graig Farmhouse

Bach-y-graig Farmhouse is an L-shaped farmhouse, likely dating to the 18th or early 19th century, with a main range to the west and a south range. The house is constructed of brickwork decorated with decayed horizontal bands of stucco, covered by slate roofs and featuring brick chimneys. A plinth rises 1 to 1.5 metres high.

The west elevation, now the front of the house, retains elements of its original symmetry despite later alterations. It is a four-window range with an advancing bay to the right. Much of the original brickwork is visible. Original 18th- or early 19th-century sash windows are set in exposed frames, although their positions have been altered, and have stone sills and stone drip moulds over the lintels. A tall archway, originally with an ashlar arch, is now filled with brickwork and contains a modern semi-glazed door with stone steps. A small modern circular window has been inserted into the angle of the advancing bay, and a single upper sash window is present in the return wall. The east-facing elevation, which looks onto the yard, also retains much original brickwork, although window positions have been altered, with three modern upper windows and one lower window. A string-course runs at mid height, passing over the rear arch of the original archway. A door is located on the right side, above a lintel of pediment form decorated with strapwork and bearing the date 1567.

The north gable of the west wing has been rebuilt using reclaimed bricks in English Garden Wall Bond and incorporates a tall chimney stack.

The west range returns one bay to the east, adjoining a six-bay range which is thought to have been a warehouse. This warehouse features a Tuscan loggia facing the yard, with stone columns on tall plinths, an oak continuous architrave, and a stone cornice. The lower storey of the loggia is now bricked-in and has modern windows or doors. The loggia cornice aligns with the string course of the yard elevation of the main house. The brickwork of the upper storey is original. It contains five window positions and one door position, the latter beneath a small gable containing a hoisting beam. The door has been replaced by a six-pane window. The window and door openings are surrounded by unbonded brickwork jambs and arches, with stone imposts and keys. On the rear (south) elevation, two original stone windows with mullions survive, along with one lacking its mullion, and one original elliptical-headed doorway.

The east side of the yard, which was the site of the original house, is now occupied by 20th-century farm buildings.

Inside the west range, now the principal part of the farmhouse, a living room features reused wainscot and a fireplace with a large bolection moulding in timber.
