Description

16 Foundry Terrace is a pair of 2-storey cottages featuring one window each, constructed with blue and dark brick fronts. The cottages have a slate roof, boarded eaves, and blue brick stacks shared between each pair. The openings are camber headed, with 6 and 12-pane sash windows and 4-panel doors that include plain overlights. The ground floor openings for Nos 15 and 16 are slightly elevated. At the rear, there are modern windows that overlook a high revetment wall from a former foundry complex. Each cottage has front gardens with contemporary simple iron railings that are arched at the top.
