Description
Mary Anns is a house dating from around the early 19th century. It is constructed of stone rubble with granite dressings, and has a slate roof with gable ends. A stone rubble stack, shared with an adjoining house, is located on the right. The plan consists of a front range with two rooms and a cross or through passage, with the entrance situated near the centre. The front elevation is symmetrical, featuring a two-window arrangement. The windows have been renewed in the 20th century. A 20th-century door is flanked by two 2-light casements with granite quoins and granite lintels that also form a flat string band. Two 2-light casements are located on the first floor, above the ground-floor openings. The interior of the house has not been inspected.
