Shirley Windmill is a five-storey brick tower mill.
It has four double Patent sails carried on a cast-iron windshaft.
The Kentish-style cap is winded by a fantail.
The tower is 21 feet (6.40 m) diameter at the base and 11 feet (3.35 m) diameter at the curb.
The mill is 55 feet (16.76 m) high to the top of the cap.

The iron Brake Wheel is 9 feet 3 inches (2.82 m) diameter and has 172 cogs.
It drives an iron Wallower of 4 feet (1.22 m) diameter with 75 teeth.
The cast iron Upright Shaft is 25 feet (7.62 m) long and has a dog clutch just below its midpoint, to allow the mill to be driven by engine without working the sails.
The Great Spur Wheel is of iron, with wooden teeth, and drove two pairs of underdrift millstones.
