Stonebridge House and 34 Bridge Street with associated raised garden wall, steps and railings

Stonebridge House and 34 Bridge Street, together with the associated raised garden wall, steps, and railings, comprise a terrace of four houses built in the early to mid-19th century. Originally used as a school and offices at the time of listing, they have since been converted to offices. The houses are constructed of stock brick in Flemish bond, with the sides and rear of flint and brick quoins. The roofs are slate-covered, with a projecting eaves on No. 28 and two chimney stacks on the ridge, each featuring two sets of eight chimney pots.

The rectangular plan features a single-fronted design for each house. The three-storey structure includes a high service basement, with a symmetrical arrangement of 2+2+2+2 bays divided by narrow channels for downspouts. The doorways of Nos. 30 and 32 are coupled in the centre, while those of Nos. 28 and 34 are at the outer ends. Ground-floor openings are round-headed with intersecting glazing bars and margin panes, set within gauged brick heads. The doorways have set-in fluted columns, panelled doors, and fanlights; the sash windows are recessed. Upper-floor sashed windows have twelve and nine panes respectively, also with gauged brick heads and raised sills. Basement windows and doors are large, segmental-headed, sixteen-pane sashed, and are located under the bridges.

The rear elevation, constructed of knapped flint with brick dressings, incorporates segmental-headed sashed windows, mainly of twelve and nine panes. A modern single-storey flat-roofed extension is attached to No. 30. A two-storey addition to the right-hand side of No. 28 is not included as part of the listed building.

The raised front garden is defined by a flint retaining wall, supporting cast-iron spear railings with urn finials. A central common gateway serves Nos. 30 and 32, featuring ramped double gates and a scrolled wrought-iron overthrow with a circular lamp-holder, in addition to steps up to the houses protected by matching railings. A long flight of restored steps leads to No. 34's entrance.

The terrace represents a good example of early 19th-century middle-class town housing.
