Description

This is a single-story and attic terrace dwelling, built with asymmetrical gables on pairs of reflected houses. The exterior is rendered with pebbledash, and the roof is covered with local slate, featuring pebbledash chimney stacks. The windows are steel-framed casements with small panes, and distinctive bell dripmoulds; however, the windows at number 11 have been replaced. The ground floor features broader windows alongside lean-to porches, with mostly boarded doors, some of which have been replaced. There are also small windows to the stairwells.

The rear elevation mirrors the front with similar detailing, including swept roof dormers to the pebbledash. The property was undergoing restoration at the time of inspection in October 1987.
