Description

Chestnut House is a 17th-century house that was refaced in the 18th century, along with an attached well house. The house is timber-frame construction, now covered in brick and some chalk blocks, with an old plain tile roof. It is two storeys high and originally had three bays, with a narrow stack bay and a projecting, single-storey well house in front of the right bay. The second bay from the right features a wide, 18th-century top-lit door, covered by a 20th-century gabled hood. There are 20th-century, wide, three- and four-light casement windows with brick arches, replacing older windows above the first-floor string. A single light is positioned above the door. 19th-century, three-light casements are also present, with the left-hand one having a segmental head. The roof is half-hipped, with a large ridge stack positioned above the door. The well house has cambered, single and small double doors, a steeply pitched gabled roof, and a string course on the gable. Inside, the left-hand room has ovolo-moulded beams and joists. The well house contains a 17th-century donkey wheel, 4 metres in diameter, with a well beneath the other end of the shaft, which extends over 100 metres deep.
