Plas Hafod

Plas Hafod is a small late Georgian country house dating from the early 19th century. It consists of a square main block with attached, contemporary and later service ranges to the rear, forming a rough "T" shape. The house is built of rough-cast stone with a shallow-pitched hipped roof covered in slate-stone, featuring oversailing eaves.

The main (southeast) elevation has two storeys and three windows, displaying a near-symmetrical design. Recessed 12-pane sash windows are present on the first floor, with projecting stone cills. A centrally-placed classical stone porch, likely added in the mid-19th century, provides the main entrance, featuring a shouldered architrave, pediment, twin Doric pilasters, a moulded cornice, and a flat lead roof. The recessed entrance door is a four-panel design. To the left of the porch is a tripartite 20-pane sash window. The original 12-pane window to the right has been removed and replaced with a modern conservatory that extends around the northeast side of the building. Two rendered chimney stacks are visible, the one on the right being larger and with exposed brick upper courses. Further modern additions exist on the northeast side, including a half-octagonal single-storey porch with a projecting square entrance bay. Upper-floor windows are 12-pane sashes, matching those on the front elevation. A single-storey, six-window modern extension is situated to the north.

At the rear, a four-bay, two-storey gabled service wing is present, with an off-centre brick stack and cusped, decorative bargeboards on the west gable. The two westernmost bays of this wing were added in the mid-19th century. The first floor has near-flush 12-pane sashes, with the westernmost being smaller. A large cart entrance is situated to the left, with contemporary boarded doors and a cambered head. A recessed, boarded door provides access to the right, with a cambered head. In the space between the rear of the main house and the service range, a 19th-century single-storey glazed porch is visible, alongside a further modern glazed extension.

The interior features a full-height hall with a single-flight stone staircase leading to a balustraded upper landing under a wide segmental arch. The staircase has a swept rail with a scroll end and columnar support, along with stick balusters, made mostly of pine, though iron balusters are used where they tie into the steps. A round-arched service entrance is located at the end of the hall, featuring fluted pilasters and simple Y-tracery fan. The ceiling has a simple plaster cornice with squared foliate bosses in the corners. Contemporary reeded doorcases are present in the hall, along with a six-panel door to the left. Inside, panelled window shutters and fluted pilasters flank a central fireplace, with a blind shutter on the left and a recessed door on the right. The chimney-piece is wooden, featuring a decorative cornice, egg-and-dart ornament, and a frieze with swags and a central urn.
