Rhiwaedog farmhouse

Rhiwaedog farmhouse is a two-storey building with an attached store and barn, and a single-storey lean-to addition projecting from the massive lateral stack at the south end. Constructed of roughly coursed stone with large stones used as quoins and lintels, the building exhibits long blocks in the south gable. A later range is distinctly different, featuring slate lintels. The roof is slate, with slightly advanced eaves and verges at the north end. The original part of the building has a shouldered lateral stack with capping along the front wall and a brick stack to the rear; the 19th-century range has a narrow rectangular brick stack at its south gable.

The principal, east-facing elevation shows the original house at the south end. A doorway is located to the left (south) of the lateral stack, and a single ground floor window is positioned to the left end. A lean-to addition, providing access via a boarded opening in the front wall, projects directly in front of the lateral stack. The rear of this older part of the house is partially obscured by a single-storey block linking the farmhouse to Plas Rhiwaedog. At the southernmost end of the range is a former store and accommodation, with a three-window range to the rear. A partially blocked doorway is visible in the left (north) opening of this rear range. It mostly features four-pane casement windows, with a four-paned light over paired shutters to the right (south). The south gable has a later doorway with brick jambs, a first-floor two-light casement window, and a similar window set into a partially blocked opening, which was formerly a doorway with the remains of a pulley system in the gable apex.

The 19th-century house to the right (north) is a three-window range, with the openings offset to the right, and a doorway between the ground floor windows under a shallow overlight. Horned sash windows with tall panes characterize the openings, with a six-pane window to the right of the door and a larger eight-pane window to the left. First-floor windows are six-pane sashes set in gabled half dormers that break the eaves line. Similar six-pane windows are at the right (west) end of the north gable.

The barn projects at right angles to the south end of the main farmhouse range and features a single central doorway and pitching door in the east gable. A single-storey addition is built against the northeast corner of the barn, accessed via a doorway in the east gable. The rear of the barn is obscured by a single-storey lean-to of profiled metal sheeting.

The left (south) doorway in the east wall leads directly to the farmhouse kitchen, which retains rough chamfered cross beams and exposed joists. A door in the south wall provides access to the rear portion of the range, originally used for accommodation and storage. This area retains plank and muntin panelling, a stone slab floor, and rough chamfered cross beams. The upper storey has a tie beam roof with angled struts and retains the drive wheel of the sack hoist mechanism.
