Bowman'S Water Mill

Bowman's Water Mill

A water-powered corn mill dated 1847, located on Mill Lane in Astwick. The mill and attached despatch building are constructed of local gault brick with slate roofs.

The main mill building is three storeys on its upstream side and four storeys on its downstream side, with an additional upper floor lit from gable ends. The east and west elevations are articulated by five bays, each with two full-height round-headed recessed panels, while the south elevation has three bays arranged symmetrically. The gable ends feature a single broad recessed panel. Windows are metal-framed fixed lights with small panes set under segmental arched heads. The east front has inserted doors and windows under concrete lintels, with a loading door at first floor level. The west front contains a large rectangular entrance at basement level in an altered opening under a steel joist, flanked by a metal-framed light, with the upper floor largely comprising metal-framed lights and some blind openings. The north front is recessed with a single upper floor light, partially obscured by an abutting two-storey block.

An octagonal cast iron overshot water wheel survives in the wheel pit. The interior contains mill floors of broad elm boards connected by ladder stairs with floor hatches at each level. The lower, ground and first floors are supported on cast iron columns, while upper floors rest on timber shafts. A broad internal doorway with vertically boarded door on the north wall at ground level connects to the despatch building. The roof is a queen strut design braced to the lower purlin.

In the basement, an intact octagonal cast iron hurst frame with classical detailing to the piers remains linked to the water wheel, with a drive shaft extending upward and a crown wheel at first floor level. Stone floor stones, hoists and bins from the upper floors have been removed.

The attached despatch building is two storeys with three bays and an external stack to the north. Its east front is symmetrical with a wide central entrance under a segmental brick arch and a first floor loading door. Windows are small-paned metal lights with opening central elements, except for the ground floor right window which is a timber sash. The north elevation has a doorway, while the west front has been extended and altered.

Historical Context

By 1855, Bedfordshire had four hundred mills producing flour. Bowman's mill is one of the few surviving examples from the mid-19th century corn milling industry on the River Ivel in mid-Bedfordshire. The river provided reliable water power, though some mills like Bowman's supplemented this with auxiliary steam power. The mill site remains undeveloped with archaeological evidence of both water and steam-powered systems surviving. A contemporary mill house stands adjacent to the property, with the river enlarged to form a mill pond and blocked penstock located within the house grounds.

Taylor's Mill in the same parish is an earlier combined mill and mill house, now converted to residential use. Stotfold Mill, also listed, was rebuilt after severe fire damage in the 1990s and restored as a working mill, featuring a similar large octagonal cast iron hurst frame, a local characteristic. Langford Mill and Biggleswade Mill are architecturally comparable but have been converted to residential use and lost their milling context. Jordan's (Holme) Mill remains the only commercially operating mill in the area, has been extended and contains later 19th-century machinery. Bowman's Mill represents one of the best-preserved examples of a mid-19th century mill in the county, retaining its dated structure, architectural integrity, sufficient machinery and surrounding archaeological evidence to remain readable as a working mill. Both the mill and adjacent mill house are prominent landscape features.
