Description
3 Nun Street is a mid-19th century house and shops constructed in painted stucco over rubble stone, featuring a slate roof and roughcast stacks on the end walls and ridge. The building has two storeys, with Nos 1 and 3 (known as Gwalia) displaying a three-window arrangement, while No 5 has a two-window layout.
Nos 1 and 3 (Gwalia) feature three 12-pane sash windows on the upper floor, with one window on the left and two on the right. The ground floor has a door and one sash window on the right, along with a shop on the left that includes a plain 20th-century plate glass window on either side of a former door, which is now also glazed. The south end wall is roughcast and rendered, although old photographs indicate it was originally slate hung.
No 5 has two 12-pane sash windows above and a large modern wood-framed shop window below.
