Numbers 48 and 50 Street

Numbers 48 and 50 Watergate Street comprise a medieval undercroft and a town house, now used as shops and a photographer's premises. The building was constructed in the medieval period, with early 18th-century fabric, the Row enclosed in the 18th century, and a refronting in the early 19th century. It is built of brown Flemish bond brick, with a tall parapet concealing a grey slate roof.

To the exterior, the building is four storeys high. The shop occupying the former undercroft has an altered 19th-century facade with a recessed part-glazed three-panel door and a three-pane window. A recessed porch to the far left contains twelve steps leading to a door with four fielded panels above two flush panels, which corresponds to the former Row level. The Row storey has a two-pane sash set forward of the wall face, with a fascia and cornice at the former bressumer level. The third storey features a canted oriel with a two-pane sash above a boarded cheek on each face, and ornate cast-iron cresting. The fourth storey has a two-course brick string at floor level, two four-pane sashes, and a stone-coped parapet. The rear gable end has a twelve-pane sash and small inserted windows to each of the two lower storeys, with a corbelled two-course brick string and a sixteen-pane sash above. The gable is stone-coped, with a chimney at the northwest corner.

The interior of the undercroft reveals a medieval west wall constructed of painted coursed sandstone rubble, along with five large chamfered oak cross-beams. The Row storey has a part-glazed inner hall door. The front room features a door with a glazed panel above a pair of smaller panels, along with early 18th-century wall panelling, featuring a row of panels beneath the dado rail and tall panels and a cornice above. The chimney breast has an overmantel consisting of one large panel above a pair of smaller ones, set between full-height fluted pilasters. Part of a Tuscan pillar from the former Row front is visible in the west embrasure of the window. The back room has a six-panel door covered to the hall, and panelling largely covered above the dado rail. A dogleg newel stair to the third storey features two plump vase balusters to each step. The front room on the third storey has a cornice and a moulded plaster beam. The open-well stair rises to the fourth storey, where the rooms have two-panel doors.
