17 Old Market Street

This is a terrace of houses, originally part of a larger mansion, dating from the 18th century. The building is constructed of stone, with some sections limewashed or painted, and number 17 rendered with a roughcast finish. The roof is steeply pitched, covered in slate and featuring rooflights, with brick end, ridge, and front stacks. The windows and doors are irregularly spaced, most with cambered heads and shallow reveals. The majority of windows are 12-pane sashes, though number 17 incorporates some UPVC casement windows, and has a replaced front door with a deep hood.

Number 19 retains the remains of a doorway with a hollow chamfer, and a corbelled-out wall above, which once supported a chimney. Number 21 has a 2-window range and the remains of a relieving arch above the large ground floor window. At number 23, a single window range also has a relieving arch above the ground floor window. Number 25, which is painted, features large 16-pane sashes set higher than at number 23, a broad relieving arch to the first floor window, and a modern-style door with overlight. Number 27 is a wider section, with a tripartite sash window on the ground floor and a round-headed doorway featuring a panelled, part-glazed door with radial glazing bars. The roof of numbers 25 and 27 is constructed of artificial slate and is not continuous with the rest of the terrace.

The original frontage of the building is at the rear, though it has undergone considerable alteration. A projecting bay at number 25 likely marks the site of the original entrance. Numbers 21 and 23 have hoodmoulds to the first-floor windows, while number 19 has a hoodmould with the remains of quadruple arched heads. High, wide relieving arches are found above the upper windows throughout the terrace. Glazing varies across the building, and ground floor extensions are present.

At the rear of the building are some stone mullion windows with dripmoulds and bearing arches. Internally, a barrel vaulted second floor runs the length of the building beneath the roof, and the great staircase has been removed.
