21, Monmouth Street

No. 21 Monmouth Street is a late 17th-century terraced house, with alterations made in the early 18th and 19th centuries. The building was refronted and the roof replaced after 1973. It is constructed of red brick with a tiled mansard roof and dormers. The house is three storeys tall, with an attic and basement, and has two windows. A shopfront, originally from the earlier 19th century, has been altered in the 20th century. The windows are recessed, 20th-century sash windows with exposed boxing, set within gauged brick flat arches. A parapet tops the building. Inside, the house hallway retains some original panelling. The ground-floor front room features a match-boarded ceiling and original cornice.
