40 King Street

This is a late 18th-century, two-storey house constructed of squared rubble stone with ashlar dressings, and a Welsh slate tile roof with stone coped verges and ashlar stacks with moulded capping. It is situated in a row and exhibits group value from the contribution to the streetscape.

The house originally presented a single-depth plan with a central hallway and a room to either side. A rear extension now provides a continuation of the hallway, along with other rooms, and a single-storey range to the rear. A room to the north of the extension has been divided into two.

The principal, east-facing elevation has three bays and a gable end stack to the north. The central entrance features a six-panel door with a rectangular fanlight above, featuring intersecting tracery, beneath a stone open triangular pediment supported on brackets. Matching six-over-six sash windows flank the entrance, and a further three matching sash windows are present on the first floor. The west-facing rear elevation includes two dormer windows and a lateral chimney stack with a brick shaft. A two-storey extension of coursed rubble stone with a Welsh slate roof partly conceals the ground and first floors, along with two top-hung, casement windows to the ground floor, and three to the first floor. A single-storey range with a gabled roof extends from the rear, featuring a round window and a large rectangular window with plate glass to its north side.

The interior features a hallway leading to rooms on either side. The north room has a plain, chamfered stone fireplace with applied timbers and a chamfered ceiling beam. The south room features an early 19th-century stone fireplace with ovolo moulding, square corner blocks and a cast-iron grate. Both rooms have decorative cornicing with foliate detailing and moulded architraves to the doorways, which also incorporate square corner blocks with a floral motif. Four-panel doors are used throughout, and the windows have moulded architraves with retained window shutters. The 19th-century rear extension contains a room with a tall, open fireplace and access to a rear range featuring a fireplace with a bread oven. A 19th-century staircase has square stick balusters, a moulded handrail and turned newel posts. First-floor bedrooms have 19th-century cast-iron fireplaces. A later staircase provides access to the attic, where partially visible 19th-century principal rafters and trenched purlins are visible.

A late 20th-century conservatory to the rear is excluded from the listing.
