Description

No. 11, Southgate Street is a town house, likely with a core dating from the 14th century, though the visible structure is primarily 17th century with later additions. The rear wing has rendered rubble foundations and walls, while the rest of the building is timber-framed and jettied to the upper floors, with slate hanging to the front, including some fishscale slates, and rendered to the left-hand return. It has a steep dry slate roof. The building originally followed a double-depth plan with a gable end facing the street. It is three storeys high, including rooms within the roof space, and has a narrow frontage onto Southgate Street with a one-window range, and a two-window range to the left-hand return. Most of the windows are 20th century replacements, with the exception of a mid-19th century twelve-pane two-light casement window on the first floor of the left-hand return, positioned above the doorway. This doorway has a 17th-century segmental-arched opening to its right and a 20th-century pair of top-glazed doors under the street front jetty. The interior has not been inspected.
