Description

Nos. 4 and 6 Lon-y-dail are a pair of semi-detached houses. They are roughcast rendered, featuring a brick centre ridge and lateral stacks. The houses have a hipped low-pitched slate roof with boarded overhanging eaves. The design is symmetrical, consisting of 4 bays, with the two end bays projecting. Originally, each bay had 8-pane sash windows with architraves and narrow sills on each floor, along with a platband running below the upper sill level across the front. There are no doors on the front; instead, there are round-arched entrances on the side. It is noted that No. 6 has replaced windows.
