45 High Street

45 High Street is an office building with shops, constructed in the 19th century. It features painted stucco and a slate roof, with no chimneys. The building is large, four storeys high, and has a four-bay front with altered ground floor shops. The upper floors display stucco quoins and hornless 12-pane sash windows on the two main floors, with smaller 9-pane sashes on the top floor. All windows are framed in moulded architraves with sill brackets. The main floors also feature cornices on consoles above, linked to the sills by shallow raised stucco details. The upper windows have lion-mask keystones.

The ground floor has modern shop fronts with beige marble facing on the piers, inscribed "Provincial House." The end wall facing Hill Lane is made of rubble stone with brick in the gable from a former chimney. There is a blocked attic window, two 9-pane sashes on the second floor, and two 12-pane sashes on the first floor. The ground floor has been altered in the 20th century, featuring a stucco band over a recessed entry leading up steps to the first floor offices. To the right, there is a long shop window, three-light with transoms on each side of a similar two-light in a former doorway. A 20th-century door is located to the far right. Above the shop window is a broad brick relieving arch, with a stucco band beneath it. The upper floors have one 9-pane and one 12-pane sash, along with two 9-pane sashes on the top floor; the 12-pane sash has a brick head, while the others have concrete lintels.

To the right of the main building is a mid to late 19th-century L-plan warehouse range of two storeys. The single-bay end wall has a hipped roof, a blocked upper window, a 20th-century window on the first floor, and a ground floor with an oak lintel over blocked openings. The south front of this range faces a rear yard enclosed by this range and another on the east. The first floor has an outside door with a concrete lintel and three large hornless 12-pane sashes in red brick surrounds above the door, which leads up modern steps. There are three similar windows, with the right one blocked. The return wing facing west is also two storeys and four bays, featuring 12-pane sashes and doors in the third bay, with the upper door blocked. The second and fourth bays have narrower windows.

The interior has been altered, but some mid to late 19th-century panelled shutters remain on the first floor front. There are also two iron columns in the rear shop.
