Description
The Old Grammar School is a former school building, now divided into four dwellings. It dates from the 18th century and features two storeys and a basement. The building has six bays in total, with the outer bays slightly projected and topped with low-pitched hipped eaves roofs supported by deep brackets. Two brick ridge stacks are topped with ten terracotta chimney pots. The exterior is rendered, revealing rubble stone beneath the basement, with an ashlar plinth and surrounds to the ground floor openings.
Nos 1 and 4 have a pair of two-pane horned sash windows on the first floor. The ground floor to the left of No 1 has a four-pane sash window within a minimal pedimented ashlar surround. The entrance to No 4 on the ground floor to the right features a broad, ashlar pedimented doorway with a similar minimal moulding to the window of No 1, accessed by a broad flight of steps, and incorporating C20 doors and sidelights. The entrance to No 1 is set within a windowless section of the left side wall, with a pilastered, pedimented ashlar surround around a C20 door.
The central section, housing Nos 2 and 3, has a sill band to the ground floor, interrupted in the centre by two ashlar-framed, moulded, shouldered doorways leading up a flight of steps. These doorways are flanked by four-pane horned sash windows within ashlar, moulded, shouldered surrounds. Plain four-pane sashes are positioned above each window, with C20 doors replacing those previously in place since 1981.
The east end wall of No 4 contains a large ashlar triple window with long, arched-headed lights, impost and key blocks; the sidelights are narrow. The east end wall and the north rear elevation feature arched cellar entrances, originally with a door and small side light set under a single, semi-circular brick low arch. This original feature survives in No 1 and No 4 (on the east end wall).
