Details

The monument includes the largely intact remains of a combined wind and
watermill, with living accommodation and the remains of associated
outbuildings, pond, race, sluices, leats and culvert. The mill, built by a
local millwright James Middleton in 1802 was extended in 1837 by the inclusion
of an additional single storey to the tower. The structure, built largely of
hammer-dressed limestone and coursed rubble, consists of a two storey
roundhouse c.12 metres in diameter, surmounted by a seven storey windmill
tower c.19 metres high. It retains much of its original plant and fittings,
including timbers from earlier post mills, gears, shafts, treadle lathe, under
and over driven mill stones converted from water-power to machine in 1912.
Wind driven plant in its original location includes the crown wheel, upright
shaft and cast-iron spur wheel driving two pairs of stones, the stones since
removed. Fireplaces on the ground and first floor, the latter including a
cl9th century ducks nest grate, attest to the mill's use as a dwelling up to
the 1880s. Hibaldstow Mill is a very rare survival of a mill combining wind
and watermill and living accommodation in one building. At present
"Hibaldstow Mill and retaining walls to mill pond and wheel-race" is a Listed
Building grade II*. The outbuildings and culvert approximately 5 metres east
of Hibaldstow Mill are Listed grade II.

Included in the scheduling are the whole of the building and its machinery,
associated outbuildings, comprising the remains of the wheelhouse, (originally
adjoining the south wall of the mill) and the site of a rectangular two-room
outhouse, separated from the mill by a track. Also included are the mill pond
and retaining wall to the west of the mill. The pond was infilled in the
1940s but still survives as a buried feature defined by the present property
boundaries. The sluices, mill race, wheelpit and culvert for the tailrace
associated with the site are also included. The surface of the access track
is excluded from the scheduling, although the ground beneath the track
including the culvert and overflow channel are included.

Reasons for Scheduling

Combined wind and watermills were constructed to maximise the energy potential
from the two major power sources for milling available before the advent of
reliable steam power in the l830s. They are a very rare monument class with
only 13 known examples recorded in a survey of 1965, with only seven surviving
as upstanding buildings. Of these seven only three, including Hibaldstow,
retain any machinery. Hibaldstow is the only mill in the country to combine
wind and water milling and living quarters in one building. James Middleton's
design represents a considerable technical achievement in its efficient and
compact organisation of internal space, which was also reflected in its
external layout, with outbuildings, culvert and the millpond condensed into a
small area. Neither of the other two surviving examples of combined mills,
Tottenhoe or Little Cressingham, is considered to be as accomplished
architecturally or technically as they retain independently constructed dual
power sources, whereas Hibaldstow achieved the combination, including
accommodation, in one free-standing building.
