Description
Bod-Ysgawen-Isaf is a two-storey central chimney house, likely dating to the 16th century, with later additions primarily from the 19th century. The structure is built of local rubble with a renewed slate roof. Distinctive crow-stepped gable parapets are present, featuring slab coping and curved kneelers in a characteristic regional style. A tall central chimney is visible, with weathered courses, although the capping is missing. A later 19th-century chimney sits on the right gable.
The main entrance is positioned off-centre, incorporating a boarded and studded door with a two-pane overlight, set within a 19th-century segmental arch constructed from finely-tooled limestone voussoirs. Flanking windows also feature segmental arches, although they now have plastic glazing. Two square-headed windows are visible on the first floor, also with the same out-of-character glazing. All windows are situated within original openings, and the evidence of former mullioned windows remains visible in the form of brown sandstone reveals. The left gable showcases a six-pane wooden mullioned and transomed window at its apex, with a 19th-century window opening on the ground floor.
A lower, storeyed addition extends from the centre rear, featuring a projecting gable and a tall chimney stack. A blocked opening is present on the right, at the rear of the main block. To the left, a long 19th-century catslide extension runs, covered with a corrugated iron roof, and includes an eight-pane 19th-century sliding sash window on the first floor. Adjacent to the left gable, and set back from the main block, is a lower, two-storey, single-bay 19th-century addition. This features a rebuilt squat end chimney and a sliding sash window. The rear elevation includes a large modern window, and a large, single-storey modern porch addition adjoins this block to the front.
The building follows a lobby-entry plan. The former hall, located on the left, is accessed via a Tudor-arched wooden entrance. The hall’s ceiling is framed with stopped-chamfered main and subsidiary beams. A wide fireplace is present, featuring a stopped-chamfered bressummer. The first-floor solar chamber above the hall was originally open to the roof and contains a fireplace with a stone-corbelled, stopped-chamfered bressummer. The bressummer is carved with the date 1595, along with the initials IL and KH, all contained within a guilloche-patterned border. A later 17th-century ceiling with wide chamfered beams has been added to the chamber. The roof is a three-bay structure, with pegged and chamfered arched-braced collar trusses above the former solar.
