Llwyn Offa Farmhouse

Llwyn Offa Farmhouse is a square-plan house dating from the Tudor-Gothic style, likely built in the 19th century. It is two storeys with attics, and each elevation presents a three-bay facade, with the outer bays gabled and slightly projecting. The house is constructed of dressed snecked sandstone with quoins, and has slate roofs with stone ridge stacks, buttressed with offsets. Decorative features include openwork bargeboards to the gables, a plinth, square hoodmoulds over windows, and transoms to the windows in the outer bays.

The west-facing front has a single-storey sandstone porte cochere with a pair of entrance arches featuring Tudor heads, incised triangles to the spandrels, and two orders of mouldings. The portico is topped with battlemented parapets, centrally adorned with a blank shield and ribbon, likely intended for a coat of arms. Diagonal buttresses with offsets are present at the angles of the portico, and each side has a narrow light with an arched head and transom. Inside the portico is a part-glazed, panelled door to the right, set under a square hoodmould, and a two-light window with margin glazing to the left. Above the portico is a similar window to the first floor. To the right of the portico is a three-light window with a transom, with the left-hand window later replaced by a plain-glazed window in the original opening. The gables each have a stepped three-light window with margin glazing. Small Tudor-arched windows with large hoodmoulds provide lighting to the attics. To the left of the front is a wing, added later, featuring a three-light window to the upper storey.

The south-facing garden front has a central glazed door with side-lights and an overlight, flanked by canted bay windows with parapets containing two-light windows. Above these are stepped windows, consistent with the west front but lacking margin glazing. A three-light window is positioned above the French doors. The east side of the house features a two-light window at the centre, infilling a former doorway. This is flanked by a three-light window to the left and a four-light window with margin glazing to the right. The upper-storey windows are similar to the south front, with the central window being two-light. The north side has a recessed, planked door with an overlight, alongside a two-light window to the left and another above with margin glazing. Against the left gable end is a brick outshut, and the gable end of the added wing has no openings.

Inside, the entrance opens into a large, square stair-hall with a glazed lantern in the centre of the ceiling and a 20th-century open-well wooden staircase to the left. Panelled doors with moulded surrounds lead off the stair-hall to various rooms.
