Description
Mathafarn is a three-story, three-window house built of rubble stone, likely dating to the 18th century. The front elevation is heavily overgrown. It has a shallow, hipped roof covered in graded slate tiles, with two brick chimneys at the rear of the main range—one yellow on the left and one red on the right—and a red brick end stack to the wing. A central porch, probably dating to the 20th century, features a flat, moulded stone roof, a 20th-century panelled door with a small light, and a plain overlight. The window openings have segmental yellow brick heads at ground and first floor levels, rising to the eaves on the second floor, with slate sills. The windows are mostly three-light wooden casements with small panes, except for the central windows which are two-light.
The east side of the main range has a 16-pane hornless sash window with a timber lintel to the right of the first floor. The west side is slate-hung and has no openings, except for a small, single-story lean-to that is also slate-hung and has a three-light, 20th-century window. A lean-to porch with a 20th-century door to the north and a 20th-century window to the west is situated against the rear wall, in the angle with the wing.
The rear wing is slate-hung on the west side and features a four-light window to the left of the porch. There's a three-light 20th-century window on the first floor with a small light to the right, and a three-light wooden casement to the left of the second floor. An outshut on the east side is two-story and has a 20th-century two-light window with a segmental brick head on the ground floor; a three-light wooden casement is above, rising to the eaves. The gable end of the wing is blank except for a datestone moved to the apex just below the stack. The datestone bears the inscription “1628 / RP / M” in relief, within a moulded surround. In front of the wing is a small, single-story gabled range of rubble stone, offset to the left, with a planked door to the left and a two-light wooden window to the right, both with timber lintels. To the right of this range are two small, brick and blockwork lean-tos.
Inside, the house has a central stair hall with reception rooms to the left and right, and service rooms at the rear. A dog-leg wooden staircase is on the right side of the stair hall, featuring narrow, square-section balusters, square newel posts, and a moulded handrail. The living room to the left has a spine beam to the ceiling with a shallow chamfer, and a large stone fireplace with a cambered timber lintel, which may have been taken from an earlier house. The reception room to the right has a plastered spine beam and a smaller, classical-style fireplace to the rear.
