Timber framed house of two medieval phases the earlier of which is a single-bay of a single aisled structure of the first half of the 15th century while the later is a slightly later formerly open 2-bay hall. There may have been a lower end which was replaced circa 1600 by a single bay. In the 18th and 19th century the front wall of the medieval phases was heightened. (2)
