19, 20, 21 and 21a South Parade

A terrace of four houses, now offices, built in the late 18th century and later altered. The buildings are constructed of stucco with painted stone dressings and have a slate roof. They stand four storeys high, with attics, and include a semi-basement ground floor. The five-bay facade is symmetrical, with the outer bays wider than the central ones. The ground and first floors have considerably recessed elevations with arcaded terraces to the front.

The ground floor has an irregular elevation with three six-panel doors flanked by late 19th-century sash windows. A flight of stone steps with a wreathed iron handrail leads to a first-floor stone-flagged terrace supported by six Tuscan columns in antis with simple iron railings. Behind the terrace, a central segment-headed tripartite sash window with glazing bars is surmounted by a tympanum decorated with swags. This is flanked by matching semi-circular headed doorcases with moulded architraves, decorated spandrels, and fluted consoles supporting moulded cornices. The doorcase to the left is blocked, while the one to the right has a six-panelled door and a traceried fanlight. Further doorcases, similar to the preceding ones but with flat heads and swagged friezes, are located on either side. The doorcase to the right now contains a 20th-century casement window, whereas the left one has a six-panelled door and radial glazed overlight. A twelve-pane sash window is at the far left, and a similar tripartite sash window at the far right. The second floor features three full-height bow windows, with unequally hung fifteen and five-pane sashes, and moulded cornices. The central bow is flanked by twelve-pane sashes in architraves with cornices, while the side ones are flanked by narrow moulded semi-circular headed recesses. The third floor has three central twelve-pane sashes and tripartite sashes with glazing bars, with narrow moulded flat-headed recesses on either side. All windows have projecting stone sills except those in the first-floor bows. There is a substantial moulded cornice and blocking course, topped by four large swagged urns to the centre three bays. The building has rendered and brick ridge and end stacks, and gabled roof dormers to the two right-hand bays. The ground floor accommodation is separate from that of the upper floors.

Nos 19 and 20 both feature open-well stick baluster staircases with ramped handrails and profiled cheekpieces. The entrance hall to No 20 has a moulded round-headed arch leading to the staircase hall. Six raised and fielded panelled doors in architraves and moulded cornices are found throughout the interior. Some original reeded fire surrounds are also present.
