Davison's mill was built in 1866 by the Canterburymillwright Thomas Holman, replacing an earlier open trestlepost mill with common sails. Milling by wind ceased in 1925, but the mill continued to work by a Ruston & Hornsbyoil engine which had been added in 1923. In April 1935, the mill was restored to full working order. The work was financed by Miss H Laurie, as a memorial to her brother Colonel Ronald Macdonald Laurie, who had died on 21 October 1927. Miss Laurie was awarded a Windmill Certicifate by the Society for the Protection of Ancient Buildings in 1936. One pair of sails was blown off in the early 1950s, and the mill worked afterwards with a single pair, assisted by the engine. Elham Rural District Council donated £100 towards the cost of repairs estimated at £500 in the 1950s. When Alec Davison retired in the autumn of 1970, the mill was the last in Kent working commercially by wind. After the death of Mr Davison, the mill was acquired by Kent County Council. A restoration of the mill commenced in 2003, with the sails being taken down on 19 July and the cap removed on 20 July. The work was financed by the Heritage Lottery Fund and Kent County Council. It was carried out by IJP Millwrights of Binfield Heath, Berkshire and took three months to complete.
Davison's mill is a four-storey smock mill with a stage at first-floor level. It is built on a low brick base only 14 inches (360 mm) high. The mill is 43 feet (13.11 m) tall to the top of the cap. It has four patent sails carried on a cast-iron windshaft. The mill is winded by a fantail. The mill drives two pairs of millstones underdrift. The Brake wheel is iron. This drives a cast-iron Wallower. The Great Spur Wheel is also of cast iron.
The engine is a Ruston & Hornsby "1912" hot-bulb engine, which was despatched from Holman's in Canterbury on 7 May 1923.
