18 and 19, High Street

18 and 19 High Street are shops with living spaces above, built in 1825 by Henry Edmund Goodridge, incorporating earlier materials. They serve as the entrance to The Corridor, an early shopping arcade. The buildings are constructed of limestone ashlar, with roofs hidden from view.

The structure has three storeys and an attic, featuring five windows arranged in a one:three:one pattern, with the ends set forward. The ground floor has modern plate glass shop windows framed by original stone Tuscan pilasters, with the centre splayed into an entrance to The Corridor. This area is flanked by two polished pink granite Greek Doric columns, which were originally stone, and features a heavy iron and glass hood above. These elements were added in the 1870s.

On the first floor, the windows are sashes set in plain reveals, with the outer windows having cornice heads on console brackets, while the centre window features a pediment on consoles. The second floor has a sill band in the centre, with windows that have architraves, including three plain sashes and two with margin glazing, which may be original. The building is topped with a cornice and a decorated attic storey that includes three lunettes, and the parapet is ramped up in the centre with a wreath.

The interiors have not been inspected. The Corridor was developed by Goodridge as a speculative project and is one of the earliest shopping arcades outside London, closely contemporary with James Foster's arcade in The Horsefair, Bristol, built between 1824 and 1825. The polished granite columns at the entrance were added in 1870, and a glazed canopy was installed in 1927, designed by A.J. Taylor.
