St Mary's Shopping Centre West Building

St Mary's Shopping Centre west building, originally a school and master's house, was built in 1856 and converted into shops in 1990. Designed by Sir Gilbert Scott, the building features brick with ashlar facades and a tile roof adorned with fishscale bands, and is laid out in an L-plan in the Gothic style.

The exterior consists of a single storey with a two-storey house to the north. The south range has three windows, while the west range has four, along with a re-entrant gabled porch. The gables are coped, and the windows have either two or three single-chamfered trefoil-headed lights. The entrance on the south range has a segmental-pointed head and is located to the left of centre, accompanied by three windows of three lights and a 20th-century gabled dormer. The porch features a pointed arch with return half arches leading to a passage, and a trefoil design on the gable.

The west range includes two entrances with segmental-pointed heads, a two-light window at the left end, and three windows of three lights. The former house has a three-light window on the ground floor and a two-light window on the first floor. The right return has a gabled wing and a lean-to re-entrant porch with a segmental-pointed entrance, alongside a two-light window to the left and a 20th-century raking dormer above the porch and gable end. There are also 20th-century glazed canopies supported by enriched cast-iron piers.

The rear of the south range is brick with a short gabled wing, while the rear of the west range features brick and ashlar on the first floor, a lateral stack, and a gabled projection from the former house. There is a short gabled wing, and a longer wing at the right end has a hipped roof with a belvedere.

Inside, the building showcases arch-braced collar roof trusses. It forms a courtyard group with the former St Mary's Church of England Infants' School to the east, located immediately south of the Church of St Mary, where Scott conducted one of his earliest restorations.
