1 Twyn Square

1 Twyn Square is a terrace of three cottages, built in the 19th century, with number 1 slightly projecting from the others. The cottages are rendered and painted, featuring a continuous deep steep-pitched slate roof with slightly swept eaves and two brick corniced ridge stacks. They are two storeys high, and each house has a two-window upper range with 4-pane horned sash windows.

On the ground floor, number 1 has two doorways with 20th-century glazed doors and an intervening sash window. Number 3 has a doorway to the right with a 20th-century glazed door and a sash window to the left. Number 5 has a step up to a segmental headed doorway to the right with a 20th-century glazed door and a sash window to the left. There is a battered base on the right side.

Number 5 has been refurbished as a shop, with boxed-in metal beams and a 20th-century staircase. There is a blocked side window with a lintel on the wall adjoining the hotel.
