Description

The former National School and National School House is a building that includes a school with an attached teacher's house, constructed in 1863. It is made of squared purple rubble stone with tooled grey sandstone dressings and features imitation slates on the roofs. The building has flush grey stone quoins and presents a symmetrical appearance to the main road, highlighted by a central tower-porch with a saddleback roof, flanked by two schoolroom windows and outer crosswings—one serving as part of the school and the other as the house.

The school section includes small-paned cross-windows set in flush grey stone rusticated surrounds, with one window on each side of the porch tower. The tower features a narrow pointed doorway with stone voussoirs, a keystone dated 1863, and a boarded door. There are small lancet windows on each side wall of the tower. Above the main eaves level, the next stage is slightly recessed and includes a roundel frame for a copper clock face. The top stage steps out again above a grey stone chamfered course and is supported by three corbels at the front, topped with a steep gable that has a narrow louvred lancet and a steep bargeboarded slate roof with a vane on the ridge.

The left crosswing has a larger cross-window in the gable and renewed plain bargeboards, with no windows in the left side wall. A parallel rear range features two cross-windows in the east end gable. The house has 20th-century windows in the original grey stone flush surrounds. The crosswing gable facing the main road has one window on each floor, while the right side wall includes a small window above a door in the angle of a gabled projection, which also has a window on each floor in the gable end. A rendered chimney is located on the south side. The interior has not been inspected.
