20 Stanley Street

20 Stanley Street is part of a terrace of two-storey brick houses, built with a slate roof and brick stacks. The windows feature dressed limestone surrounds with monolithic jambs and round heads with keystones on the lower storey. The two-light windows have wooden mullions, small-pane casements, and transoms in the lower storey. The houses are arranged in pairs of three bays, with the central bay containing a passage that has a plain round brick arch, leading to boarded front doors and the back yards. Above the passage, there is also a window in the central bay. On the right-hand end, the passage provides access to No 23 and the yard behind 9 Wexham Street. The return elevation on Wexham Street has three windows and features a boarded door beneath a round-headed overlight and plain brick arch, with the upper left-hand window blocked. A window was added in the 20th century at the right end.

The left gable end of No 13 is roughcast, and the rear of the property has small-pane horizontal-sliding sash windows. This terrace is part of a group that includes 13-23 Stanley Street and 9 Wexham Street.
