29, 31 and 33, Castle Street

A range of three houses, originally built as one unit in the 18th century, with alterations and additions in the 19th and 20th centuries. The building is timber-framed and plastered, with an ashlar lining, a brick plinth, a slate roof, and red brick stacks. It has a U-shaped plan, following the line of Castle Street with rear wings extending northwards to the east and west.

The front, south elevation has an irregular three-window and three-door arrangement under a hipped roof with two stacks, one at the west end and one positioned between numbers 31 and 33. The ground floor of numbers 29 and 31 has a window to the east of the door, while number 33 is the reverse. All doors are four-pane designs; the original door at number 29 retains a flush, bead-moulded appearance. The windows are recessed into the wall, each with three casements of 6x4 panes. Number 31 incorporates a cellar light below its ground floor window. The first-floor windows are flush with moulded architraves and feature two sashes with glazing bars, divided into 4x4 panes.

The rear, north elevation reveals a plastered street range with gabled wings at each end. An easterly wing extends along the path to Lower Square and features a central, flush gable. The ground floor has a boarded door and a mixed sash window of 3x1 panes combined with a 3x2 pane section. Above this is a two-light casement window with 2x2 panes, alongside a fixed casement window with glazing bars and 3x4 panes. A stack is positioned behind the wing. The south wing has a two-light window of 20th-century origin. A simple lean-to shed is located on the east inner face, below a pair of two-light and three-light windows. The eastern wing features a boarded door with two single-light windows and two-light casements. A gable stack is situated at the junction of the units, with a second stack at the north end.

The east side elevation, facing Lower Square, showcases the end of the street range, followed by the eastern wing and a lower extension. The lower extension is weatherboarded with stacks at each end, alongside a brick and cobble plinth. The ground floor has a sash window with glazing bars (4x4 panes), a boarded door, and a three-light casement window. The first floor features a single-light and a two-light casement window followed by two similar sliding sash windows with 6x3 panes.
