Beeleigh Steam Mill and bridge over tail race

A steam mill, the ruins of an earlier water mill, and a connecting bridge, dating from the early 19th century. The steam mill is constructed of red and cream Gault brick, topped with a hipped slate roof featuring a blue clay ridge and hip tiles.

The exterior features embellished elevations facing both the North East and South East towards Beeleigh Falls House. The South West elevation is a mix of Gault and red brick, displaying a series of circular tie-bar plates. A large semicircular-arched opening provides access to the engine, which remains visible. The segmental-headed door opening, along with other smaller openings, are now largely blocked or concealed by ivy. The short North West elevation is of Gault brick, with a centrally placed segmental-arched opening containing a cast-iron window with 24 small panes. Set into the north corner is the truncated base of a former chimney that wraps around to the North East elevation. The North East elevation has four broad semicircular-arched recesses, each featuring similar 24-pane iron windows on the lower storey. The South East elevation mirrors this design, with cast-iron windows on both storeys and two semicircular-arched recesses.

To the South West, the remains of the water mill consist of a rectangular enclosure of varying height brickwork, using both Gault and red brick. Surviving openings indicate former doors and windows, and two large chambers remain where breast-shot water wheels were located, alongside two barge docks for unloading flour and grain. To the South East, a bridge provides access to the former mill house, Beeleigh Falls, and features red brick parapets, stone copings, and two semicircular arches.

The interior of the steam mill is divided into two compartments by a brick partition. The north-western compartment is open to full height and contains a complete iron, double-acting compound steam engine from 1845, manufactured by Wendworth. Alongside it is an 'Elephant' boiler with two safety valves and a firebox. On the ground floor is an iron upright shaft with a large spur wheel, the driving machinery, and a circular-plan iron husting. The upper floor retains emplacements and drive spindle ends, designed originally for five pairs of stones. The earlier water mill was a five-storeyed building clad in weatherboarding, originally housing 12 pairs of stones and two water wheels; it was destroyed by fire in 1875.
