Description

The Former National School and Schoolhouse is a mid-19th century building that consists of a school and an attached two-storey schoolhouse, constructed as a single range. The main elevation of the schoolhouse faces the street. The school features a staggered wing with two units: the infants classroom is located in a cross wing at the southeast end of the schoolhouse, while the girls and boys classrooms are in a wing set at right angles to the rear. Access to the girls and infants classrooms is through a lobby situated between the schoolhouse and the infants classroom, while entry to the boys classroom is via a gabled porch at the northeast end of the rear wing.

The exterior is faced with local rubble stone arranged roughly in courses, complemented by freestone dressings. The building has steeply pitched slate roofs with stone copings and ashlar stacks. The schoolhouse features a brick gable stack that is corbelled out at the northwest end, along with an axial stack. The school is fitted with horned sash windows throughout, although some are now boarded over. The infants classroom has large gable windows with ventilation slits above, and the southwest gable includes a corbelled chimney. The southeast elevation has two 4-pane sash windows. The girls and boys classrooms each have tripartite windows made up of 8-pane sashes, with the girls classroom located to the left and featuring a window in an advanced gabled wing, topped with a corbelled chimney. The northeast porch has a steeply pitched gabled roof, with entry through boarded double doors beneath a segmental-headed fanlight. The schoolhouse itself is a two-storey, four-window range, with the doorway offset to the left end, and the first-floor windows are 2-pane, side-hung casements.
