Castle House And No 19 (Carriage House)

Castle House and No. 19 (Carriage House) are two houses, originally a single property, dating to the mid to late 18th century, with remodeling circa the early 19th century and later 20th-century modifications to the front elevation. The construction is stone rubble, formerly plastered to the front, with a slate roof, gabled at the ends. There are two rear stacks to the main range, a right-end stack, an end stack to the rear wing, and an axial stack to that wing.

The building follows an L-shaped plan: the main range, facing Castle Street, consists of two adjoining houses (Castle House on the left) with a rear left wing set at a right angle. The rear wing, featuring 18th-century details, appears to be the earliest part, while the single-depth main range showcases early 19th-century features. Castle House, the left-hand block with three bays, has two principal heated rooms, one on either side of an entrance passage containing an open-well staircase in a central rear wing. The three-bay right-hand block, No. 19, has a smart early 19th-century front elevation, although the remains of an archway on the right suggest modifications. A single-story lean-to projects from the rear.

The front elevation is two stories high, with a 3-bay left-hand block (Castle House) and a roughly symmetrical 3-bay right-hand block (No. 19). Castle House features a molded cornice and dentil frieze; the left and right pilasters and projecting architraves to the windows are later 20th-century additions. A 19th-century recessed panelled front door is centered in Castle House, topped with a rectangular fanlight, panelled soffit and reveals, fluted half columns, and an entablature. The ground floor windows are 12-over-8-pane sashes, while the first floor has 12-pane sashes. No. 19 has a recessed panelled front door with a panelled soffit and reveals, pilasters, and a cornice. 20th-century architraves frame the windows, similar to those of Castle House. The first floor has three 12-pane sashes, while the ground floor has a 12-over-8-pane sash on the left and a 20th-century insertion into a blocked stone archway on the right. The rear wing of Castle House contains some 12-over-8-pane sashes with thick glazing bars, likely from the mid-18th century. The stair wing has a hipped slate roof and a round-headed stair sash with glazing bars.

Inside Castle House, 19th-century joinery is evident in the main block, including a good stick baluster staircase with a wreathed handrail, and a circa early 19th-century marble fireplace in the ground floor room to the right. The rear wing retains 18th-century joinery, including two-panel doors and fixed cupboards with fielded panels. In 1761, John Goodman, a sergemarker, lived at the property; later, it was occupied by a leather merchant, Hulland.
