Plas Bellin

Plas Bellin is a country house, primarily dating from the 19th century, with a significant earlier 17th-century block at the rear. The main, two-story block has five windows and is faced with stucco, featuring a shallow-pitched slate roof with deep eaves. A projecting bay, built in the early 20th century, sits centrally and has chamfered corners, a bow window on the first floor, and an exposed stone porch with double entrance doors, flanked by windows on each side. The two bays on either side of the central bay each contain two windows; the ground floor has 12-pane sashes, while the first floor has 6-pane sashes. A lower block with a hipped roof and a glazed entrance doorway is located on the left-hand side.

Behind the 19th-century block is a lower, remodelled block dating from the 17th century, again with a hipped slate roof and stucco to the east where a projecting stone chimney stack with a brick top is flanked by a 9-pane sash window to the left and a smaller sash window to the right on the first floor; on the ground floor, there are 12-pane sash windows on either side. The rear elevation, facing the yard, is of exposed stone and features a similar chimney towards the right. The ground floor has a square window and a three-light stone mullioned window, while the first floor has 9-pane sashes.

A two-story, four-window wing facing the yard (aligned north-south) has a hipped slate roof, a brick chimney, a stone ground floor, and a brick first floor. The first floor has four small-pane casement windows, while the ground floor has a doorway with a two-light cambered window to the left, followed by two similar three-light windows and a smaller cambered window. The rear of this range is constructed of stone and brick from various periods. A single-story-plus-attic brick range extends from the yard, aligned east-west.

The interior of the 19th-century block has been altered but retains a wooden staircase leading to a hallway with a high, beamed ceiling. The interiors are generally simple. A corridor links the 19th-century block to the 17th-century block. To the right of the corridor is a stone arched doorway leading to a crosswing, now used as a chapel, which features heavy ovolo-chamfered ceiling beams with stops, a stone fireplace with a cambered lintel and moulded jambs, and a cellar below containing a stone mullioned window and some original massive beams, including a heavy beam over a restored timber-framed partition with a doorway featuring moulded jambs. The dining room has heavy chamfered beams with ovolo mouldings and stop-chamfered joists, as well as a stone fireplace on the north wall. A heavy beam spans a restored timber-framed partition with a doorway, and a square opening is situated to its right. This room is also accessed from the corridor via a stone arched doorway with a massive lintel and broach-stops to the jambs. Heavy timber-framed construction continues in fragmentary form into a corridor and into the toilets to the east.
