The structure itself is a three-bay, gable-ended building of two storeys. What makes it architecturally distinctive is the mix of window types: the ground floor openings are pointed, giving the facade a faintly ecclesiastical quality more often associated with church design of the period than with vernacular schoolbuilding, while the first floor on the north elevation uses large rectangular windows. Unusually, the original glazing bars survive throughout, a detail that tends to disappear early in a building's life as glass breaks and repairs accumulate. A pointed doorway in the east wall continues the Gothic note, and lean-to additions along the south and west walls suggest the building acquired ancillary uses or extra accommodation at some point after its original construction.
