Ty Brith, and attached courtyard wall

This is a large townhouse, dating back to the early 18th century, which has been divided into three separate dwellings, each with its own roof. The exterior is stucco-rendered and painted, with a slate roof, sprocketed eaves, and prominent rendered ridge stacks. The main frontage on Priory Street, known as Ty Brith, features a central gable containing a small arched attic sash window with glazing bars within a rectangular frame. The first floor has a three-window range of 12-pane sashes set within reveals with shallow sills, a quoin strip, and a plinth. An early Tudor-arched doorway, constructed of painted stone with light mouldings stopped at the base, features a wooden studded door with long hinges and an unusual small hexagonal upper light, sheltered by a shallow bracketed gabled hood. The rear, south-facing elevation has a single window range of similar sash windows, with canted bays on the ground floor. The side elevation facing Twyn Square is gabled, with 12-pane sash windows on three levels, alongside a larger multi-pane fixed window. An earlier smaller square opening with two iron bars is visible to the left. To the lower cross wing, forming Ty Brith Cottage, are paired sashes. Two smaller, deeply set lights indicate the thickness of the wall. A lower hipped roof wing extends, pebble-dashed to the rear, and features a brick-surrounded doorway. An old rubble wall with blocked features is attached, with a doorway leading to Ty Brith Cottage, flat coping, a small pointed brick-arched opening that sweeps upwards to join a former stable block. Ty'r Ardd, the wing parallel to the main frontage, has rendered end stacks, slightly swept eaves, and a two-window range of tripartite sashes. A large restored conservatory is attached to the south gable end, built against a partially external chimney stack.

The interior of Ty Brith is stepped up to the north. The central hallway has a Tudor-arched doorway with a 19th-century decorative wood and coloured glass inner door, alongside a dado and flag floor. The front right room contains an early fireplace with a chamfered stone lintel and niche. Throughout the house, there are panelled reveals, six-panelled doors, shutters, and wide floorboards. An open well staircase to the rear includes decorative treads, a repaired/replaced balustrade, and a circular roof lantern for illumination. The first floor retains a small Victorian cast-iron grate; a north-facing room has deep chamfered spine and cross beams. The top floor has three fine moulded wooden Tudor-arched doorways and two wooden fire surrounds with bolection moulding. In the north section, the roof structure is visible, showcasing an A-frame truss with angled struts and three rows of trenched purlins, staggered to the left and continuous to the right, culminating in a ridge piece.
