Killick's mill was built in 1801 by three brothers named Killick from Strood.[2] Unusually, the mill is hexagonal in plan. Most smock mills are octagonal in plan.[3] The mill was run by the Killick family until 1889 when it was sold to the Norton family.[2] The mill last worked by wind in 1929, and then by oil engine and electric motor until the 1965.[4] The mill was acquired by Kent County Council in 1960 and restored by E Hole and Sons, the Burgess Hillmillwrights at a cost of £4,375.[5]
Killick's Mill is a three-storey smock mill on a two-storey single-storey brick base. There is a stage at second-floor level. It has four double patent sails carried on a cast-iron windshaft. The sails are 27 feet (8.23 m) long.[5] The mill is winded by a fantail.[2] The wooden Brake Wheel is 6 feet 6 inches (1.98 m) diameter. The Wallower and Great Spur Wheel are of cast iron.[3] When the mill was built, it had two pairs of millstones. Later a third and then a fourth pair were added. One of the added pair of stones came from Richardson's mill, Boughton under Blean, as did the 15 horsepower (11 kW) auxiliary oil engine.[2] The stones are driven overdrift.[3] At one time, the mill generated its own electricity to power electric lights within the mill.[2]
