Breachwood Green Mill Breachwood Green · Hertfordshire · England

Breachwood Green Mill stands on Windmill Road at King's Walden, west of Roundabout Plantation and close to Breachwood Green. Earlier windmills are recorded in the parish in 1329 and 1762, but the surviving tower mill belongs to the nineteenth century. It was built around 1859 as a five-storey brick tower corn mill.

The first recorded miller was William Dellow in 1861. His son, also William Dellow, continued the family connection and worked the mill until 1900. The mill was equipped with a domed cap turned by fantail, four patent sails, a cast-iron great spur wheel, and two pairs of millstones. The tower measured about 24 feet in outside diameter at the base, with brickwork about two feet thick, and rose about 42 feet to curb level.

The mill lost its sails by 1930, and by 1936 the cap survived only as a bare frame. The Grade II listed structure remained as a distinctive tower mill in the agricultural landscape. Later conservation assessment described the building as a nineteenth-century red-brick tower mill with iron and timber remains of mill fittings, the ogee cap removed, and remains of the curb, frame, and part of the fantail structure surviving.

The tower was converted to residential accommodation in 1998. During or after conversion, the brick tower was clad in weatherboarding, so that the former tower mill now visually resembles a many-sided smock mill. Despite this change, the building preserves the form and location of Breachwood Green's nineteenth-century tower corn mill.
