Description
The Sir Walter St John’s Grammar School building dates primarily from 1859, with later additions. The oldest part was designed by Butterfield in an asymmetrical 14th-century Gothic style. To the south-east is a recessed two-bay ground-floor range with half-dormers. The main part of the original building features a prominent two-storey gabled bay. The facade is constructed of red brick with pale gault brick diaper decoration, stone dressings, and a slate roof with crocket tiles. The gabled bay has twin plate tracery windows on the ground floor. Above these is a bandcourse, a recessed plaque displaying the school's name, and a cillband. A tripartite traceried window rises from the cillband, projecting into the diaper pattern of the gable. The recessed range contains a twin-arched entrance featuring an inscription reading 'Rather deathe than false of faythe' within a pointed arch, all decorated with quatrefoil moulding. The upper floor's half-dormers have twin cusped lancet windows, each with an elaborate roundel above. An octagonal open wooden lantern with a spire and weather vane rises from the junction of the gabled bay and the recessed range. A six-bay, 15th-century Gothic-style extension was added in 1915 by A H Ryan Tennyson, built in red brick with stone dressings. Further sympathetic extensions were added in 1925 and 1938, which are not considered to be of particular interest.
