Description
11-15 Bridge Street is a shop with a dwelling above, now converted to offices, built in an eclectic late Victorian classical style. The building has three storeys and four bays, featuring painted roughcast walls and moulded sill bands. It has a hipped slate roof with bracketed eaves and a roughcast ridge stack. The Bridge Street elevation is asymmetrical, with a narrower bay to the left of the centre that lights the stair. This bay has a replaced window with a pedimented architrave on the middle storey, and a keyed oculus above. The other three bays have camber-headed three-light windows, renewed in moulded architraves on the first floor, and two-pane sashes in moulded architraves above. Each window is defined by a pedimented head in the outer bays, with a triangular pediment in the centre-right bay. Of the original ball finials at the eaves, one finial is still retained on the left of the left-hand bay. The shop front is from the late 20th century.
The distinctive rounded corner bay features pedimented architraves for two-pane sashes on both storeys. Above this is a moulded cornice leading to a steep pyramidal roof topped by a central turret with panelled sides and a conical roof.
The rear elevation has a stepped parapet and replaced windows.
