Tan-y-castell

Tan-y-castell is a terraced house built with painted brick in Flemish bond, featuring a slate roof and a small brick stack to the right of the center, as well as a brick stack on the rear southeast wing. The house stands three storeys tall and has three bays, with the top floor showcasing three early 20th-century wooden casement pairs. The original structure includes a full-width band over the ground floor and a band over the first floor that stops just beyond the windows. The windows are three 4-pane sashes, which have replaced the original 12-pane sashes seen in an old photograph, and feature gauged brick heads. The ground floor has a ledged door to a through-passage on the left, which has a cambered head.

A notable feature of the front is an early 19th-century shop front located in the middle and right sections. This shop front has thin reeded pilasters on the outer sides, a broad curving fascia, and a cornice that slightly projects forward over the central door. The two broad shop windows gently curve outward towards the center and each consists of 32 panes set on a painted brick base. The recessed central doorway has deep flush-panelled reveals and a flush-panelled six-panel door with lozenge tracery in the overlight, along with lozenges carved on the lintel above the door.

The rear of the house has a whitewashed rendered gable with a brick stack on the roof slope and a leaded cross-window on the first floor. The front is paved with stone setts.

Inside, there is a square lobby with two fielded-panelled six-panel doors: one leading to the shop on the right and the other straight ahead to the house. The left room on the ground floor features two stopped and chamfered ceiling beams, while the right room has two similar beams with ovolo stops. The left room also has a brick south wall with a large fireplace arch. The staircase, which is crude in style, is late 17th century but likely dates from the 18th century. It has a solid closed string and pierced wavy slat balusters, with a matching landing rail.

In the rear wing, there are two large north-south chamfered beams on each floor, with the northern end featuring a timber-lintel fireplace that backs onto the front room chimney. The first floor has two massive axial beams in the front rooms and two beams at right angles in the eastern room. There is a fireplace on the back wall without a surround, and a leaded cross-window in the back wall. Timber-framed partitions separate both floors from the rear wing. The steep attic stairs have flat balusters, and the attic retains heavy purlins at both the back and front.
