Twynysheriff

Twynysheriff is a farmhouse featuring roughcast walls, a slate roof, and red brick end wall stacks. It is two stories tall with a three-window front that includes small-paned sash windows. The first floor has a 16-pane sash window on the left, a small 12-pane sash window in the center, and a higher 16-pane sash window on the right. On the ground floor, there is a 20-pane sash window on the left, a roughcast gabled porch in the center with a Tudor-arched entry, and a French window on the right. Inside the porch is a fine 17th-century studded oak plank door with iron strap hinges and a chamfered oak doorframe. The windowsills are made of tooled stone. The east end has a stone-tiled lean-to, while the west end features a lean-to pantry.

At the rear, there is a red brick lean-to on the left with a door and window, and a window in the inside end wall. The main rear wall of the house is made of rubble stone and has a pair of casement windows and a door. The northwest rear wing includes a stone chimney and a notable three-light diamond mullion window on the inside east wall. The west side of the house has a dormer.

The original house has a two-room plan, with added rooms and a stair at the rear. The east ground floor room features three cambered beams that are plastered over and a 20th-century fireplace. The west hall, refitted in the earlier 18th century, has stone flags and five deep chamfered beams with stepped hollow stops. There is a post and panel partition on the east wall, and a west end 18th-century fireplace with pilaster jambs and a lintel that has quadrant curved corners and a keystone. To the left is a cupboard with a panel door, and to the right is an oak door that was originally external but now leads into the lean-to pantry down stone steps. A built-in dresser is located on the rear wall. The rear door is also an oak plank door in a 17th-century ovolo-moulded frame, aligned with the front door. There is a straight flight of stairs to the rear, located outside the original rear wall, which features some reused panelling. The northwest rear wing has an internal spine wall with an oak stud partition, heavy beams, and plank doors.
