Former School Room, New Bethel, and attached wall

The Former School Room at New Bethel is a single-storey building that was originally a Nonconformist school, constructed in 1847. It features stone walls with some yellow brick dressings and a slate roof adorned with decorative terracotta ridge tiles, which is half-hipped at the southwest end. The stone rubble is laid in snecked courses. The building has a six-window front, with a gabled porch located southwest of the center. The three windows on the southwest side are more closely spaced, and all windows are 10/10 pane casements with stone sills. The porch has a doorway with a moulded six-panel door and a barely legible stone plaque above it that reads "Islwyn School Erected 1847."

At the northeast end, there is a smaller adjoining single-storey outbuilding, also with stone walls and a slate roof. The ground in front of the building, to the northwest of the front elevation, is set high above the road and enclosed by a stone rubble boundary retaining wall with rounded stone coping. This wall extends northward as far as the chapel house and features a flight of stone and brick steps that ascend between stone walls to the school, with iron railings. The boundary wall to the southwest descends in height as the ground rises. There is also a rooflight on the front elevation. The building has been converted into a dwelling.
