Former National School

The Former National School is a single-storey building constructed from coursed grey rubble stone with thin red brick banding and slate roofs. The window heads and flush sills are made of limestone ashlar, while the jambs are in sandstone. The building has a T-plan layout, originally featuring a short hipped centre porch projection, which was extended in 1867 to create an additional classroom.

The main schoolroom has a chimney stack located on the ridge of the lower projection, near the junction, and is adorned with crested ridge tiles. A fleche sits on the ridge of the main range towards the southeast end. The added classroom includes a large battered side-wall stack, which has been truncated at the eaves. The windows, which were similar to those on Withers' Cardigan Guildhall, originally had small panes with a central timber mullion and shouldered heads, but these have all been replaced since 1989 with plain hardwood glazing.

The main range features subtle brick banding that corresponds with the window heads and sills, including a double band at sill level and three single bands in the gable ends, with one on the side walls. The gable ends each have two long windows with chamfered shouldered surrounds and pointed relieving arches, along with small rectangular vents. The sides of the building have two windows on each side of the projecting wing, which also have similar shouldered heads and relieving arches. The projecting wing retains its original 1859 doors on either side, which feature similar heads and relieving arches. A ledged door with strap hinges remains on the southeast side. Adjacent to this is the classroom addition from 1867, which has a broad chimney breast with set-off sides (the lost stack previously had two further pronounced set-offs). The northwest side has two flat-headed windows, one of which retains an original 12-pane sash. The gable end features a single long window with a segmental-pointed head. At the northeast corner of the main range, a flat-headed doorway with an ashlar lintel connects to the corner of Llanarth villa, the former teacher's house.

Inside, the main range consists of a single room with a stone side-wall fireplace that has a five-sided beaded opening and a heavy shelf. The roof is supported by six scissor trusses, with cusping in the angles of the purlins and trusses.
