Description
18 Gwynant Street is part of a group of four 2-storey workman's cottages built in the second quarter of the 19th century. Constructed from roughly-squared stone blocks, the cottages feature a continuous slate roof with a tiled ridge and plain, shared chimneys. Each cottage has a single window with returned slate labels and slate lintels on the ground floor. All the doors are from the 20th century. Notably, number 18 retains its original 16-pane sash window on the ground floor, while numbers 18 and 19 have smaller 19th-century 16-pane sashes under the eaves on the upper floors; the other windows are modern.
