School Room at Llidiardau including adjoining wall to W

The building is a small mid-Victorian village school room, featuring a simple rectangular hall with two windows. It is constructed of rough-dressed slatestone and has a medium-pitched slate roof with plain bargeboards. A squat red brick chimney is located on the right side. The road-facing elevation has two large vertical rectangular windows that extend up to the eaves, complete with projecting slate sills and iron quarry glazing. To the left, there is a 20th-century rendered lean-to porch with a slated roof, which includes a boarded door and a steel-framed window on the left.

Adjoining the school room on the right and extending westward for about 20 meters is a contemporary or near-contemporary rubble wall. This wall stands approximately 1.5 meters high and features crude "cock and hen" coping primarily on the east and west sides. It ends at the western side at the forecourt of the Llidiardau chapel. The interior was not inspected during the survey.
