Description
Old Tan House is a 19th-century double-fronted house built from red sandstone rubble with some ashlar dressings. It features a hipped slate roof and rendered stone stacks. The building has a symmetrical two-storey front with projecting gable chimneys. The windows are hornless sash types; the window heads have slightly cambered arches made of stone voussoirs and thin stone sills. On the first floor, there is a central 12-pane sash window flanked by 16-pane sashes on each side. The ground floor has a central entrance doorway with a semi-circular voussoired arch, a glazed overlight, and a 6-panel door, with 24-pane hornless sashes on each side. The south elevation is rendered and features 20th-century glazed doors on the ground floor and a 16-pane sash window on the first floor. The building was not available for inspection at the time of the resurvey.
