Description

St Anne House is a symmetrical seven-bay Georgian building dating from the 18th century. It stands three storeys high with an attic, constructed from rough dressed stone and topped with a slate roof. The building features rubble gable parapets and plain end stacks with weather coursing. The central entrance is recessed and has a moulded wooden doorcase with a Victorian four-panel door that includes upper arched lights. There is a 20th-century wooden porch with a pediment supported by plain chamfered columns. The windows are slightly recessed and styled as modern 12-pane sashes. The roof has a three-bay pediment with a multi-pane glazed oculus, complemented by plain 19th-century bargeboards and a wooden finial. Additionally, bays one and six have deeply recessed entrances at the ground floor, which appear to be from the 20th century, featuring modern part-glazed doors.
