Rhyllon Farmhouse

Rhyllon Farmhouse is a large house, likely dating to the 18th century, constructed of brick with slate roofing and brick end chimneys. The front and left elevations display Flemish bond brickwork, while the rear and right elevations use English Garden Wall Bond. The symmetrical front elevation features three windows with a central eight-panel front door and overlight, sheltered by a reconstructed porch with curved steps. The windows are paired with single-pane sashes, with the exception of a flat-roofed bay window on the right ground floor, which has larger, similar sashes. Segmental brick arches are present above the windows, and they have stone sills. Two small dormer windows are set into the front roof slope, each equipped with horizontally sliding sashes and slate-hung cheeks.

The left side elevation is also formal and symmetrical, with central two-light sash windows, a single-light sash window to the left, and blind brickwork windows to the right. At attic level, the outline of a former second-floor window can be seen; this has been bricked up, retaining only two small lights. The right side elevation is largely plain, punctuated by two small attic windows.

The rear of the house is irregular; it includes a stairwell wing to the left and a parallel secondary block to the right, featuring an end chimney and several single-storey annexes. The rear windows are mostly 12- or 16-pane sashes, with the exclusion of more modern casements in a later lean-to annexe.

The interior remains of a high quality. There’s a broad entrance hall at the center of the house; a large drawing room on the left, formed by combining two earlier rooms and marked by two pillars where the original wall stood. The fireplace associated with the rear chimney has been blocked, but a stove flue now runs within it. A smaller dining room is located to the right, and a former housekeeper's room is at the rear. Original window shutters survive on ground and upper storey windows.

The main staircase is broad with a half-landing, a moulded handrail, turned balusters, and bracket tread ends. A servants' staircase at the rear of the dining room begins with stone steps from the now-blocked cellar; the upper portion of this staircase is timber-framed with a closed string, chamfered newel post, and shaped handrail. The lower flight boasts a balustrade with crossed timbers, possibly from the late 18th century, while the upper flight has a plain balustrade.

The cellars are extensive, containing large fireplaces and area windows. They originally housed the kitchen, wine cellar and wash-house.
