Listed Building: TORR VALE MILL ATTACHED WEIR SLUICE GATES WATERCOURSE WALLS HEADRACE ARCHES RETAINING WALLS AND STEPS (1119721)

Textile factory, including attached weir, sluice gates, watercourse walls, headrace arches, retaining walls and steps. C. 1790, with major alterations and additions in 1860, and fully-developed by 1879. Rubble grindstone walling, with dressed quoins and dressings to door and window openings. Welsh slate roof coverings. Complex comprised of 3 linked principal components, and ancillary buildings extending roughly north-south, the site defined on the western and north-western edges by the River Goyt. These components are; OLD MILL, c.1790 to the north, with a narrow LINK BLOCK connecting it to COTTON MILL, 1860, to the south-west, and with a later brick BOILER HOUSE attached to the south-west side wall. Behind this, WATERCOURSE WALL and TAILRACE ARCH. Attached at the south corner of the 1860 mill, and extending southwards, the L-shaped WEAVING MILL, c.1860. Within the angle of the L-shaped range, a tapered square CHIMNEY, with attached RETAINING WALL extending north and south to define approach to short flight of stone STEPS. These lead into a narrow yard bounded on the cast side by a range of service buildings, including MILL HOUSE, OFFICE,, OPEN-FRONTED SHED, WORKSHOP and SMITHY. To the rear of Old Mill, the mill WEIR,, with attached raised WATERCOURSE WALLS, RETAINING WALLS, SLUICE GATES and HEADRACE ARCHES with STEPS above. OLD MILL: 4 storeys, originally 5 and of 3 bays. Possibly built as an unpowered loomshop, with 2- and 3-light flush-mullioned Windows, some of which survived radical late C19 alterations. Lower 2 storeys with blocked C18 doorways. East end with inserted taking in doors to upper floors. INTERIOR,: late C19 floors, with timber spine beater supported on cast-iron columns. Floor of upper storey removed, with tall cast iron columns supporting timbers above. Late C19 roof trusses with angled struts, and a vertical tie rod. LINK BLOC 4 storeys, 4 bays with stacked tall window openings with C20 frames. Stacked taking-in doorways off-centre, with stone surrounds, and with heads set lower than adjacent window heads. INTERIOR: lower 2 storeys of fireproof construction, comprised of transverse brick ceiling vaults supported by a single row of cast-iron columns. Upper floors of timber construction, below king-post roof trusses. COTTON MILL: 5 storeys, 11 bays, with triple-ridged roof behind shallow parapet. Wide end wall with 6 windows to each storey. Stacked tall rectangular window openings with plain heads and cills and C20 frames. Staircase with later 2 storey rectangular entrance lobby to south-east corner. INTERIOR: fireproof construction for both the mill and the attached stair tower. Mill with transverse brick ceiling vaults supported on 2 rows of cast iron columns and cast iron beams with side flanges and circular yokes at the junctions with the tie beams. Cast-iron bearing boxes and blocked floor traps for an upright power shaft are visible on the north-cast end avail. The basement incorporates the remains of an earlier water~powered mill with 2 wheelpits, one of which remains accessible through a tail race arch in the north-west corner of the building. The attached single-storeyed BOILER HOUSE is a replacement for an earlier building in the same position. Shallow pitched roof with small ridge louvre. The building still houses a single Lancashire boiler. To the rear, the rubble stone WATERCOURSE WALL for the cast tailrace to the cotton mill, and the shallow stone TAILRACE ARCH for the western tailrace. SPINNING MILL: L-shaped range with main block of 8 bays, extending into 3-bay wing to the north-east. Stacked tall rectangular window openings with plain heads and calls and C20 frames. End plates to tie rods between windows to lower storeys. INTERIOR: timber floor construction, with cross beams supported originally by a single column of slender cast-iron columns. At ground floor level, these were supplemented by columns on either side of the originals. Substantial roof trusses, with struts inclined inwards to support collars which carry short king posts. CHIMNEY forms part of 1860 development and was linked by underground flue to Cotton Mill basement, which housed the steam engine. Range of ancillary buildings extending northwards from south end of yard includes a 3 storey, 2 bay HOUSE of coursed grindstone, with a ground floor 8 over 8 pane sash window, and windows with C20 frames above, a 2 storey, 3 bay OFFICE with a long ground floor office window, first floor 2 over 2 pane sashes, and a panelled, half glazed L-shaped interior corridor. Further north, an OPEN-FRONTED SHED, with workshops above, linked to a taller 6-bay WORKSHOP of rubble gritstone, formerly joiners shop, with mechanics shop above, and added SMITHY to rear, with forge remaining in situ. To north~east, at rear of Old Mill, the masonry curved WEIR extends the full width of the River Goyt from the WATERCOURSE WALL. At the north end of the wall, a pair of cast-iron sluice gates and bevel -geared controls are located at the mouth of the headrace, at the end of which are masonry HEADRACE ARCHES, one within the other, with a flight of steps over, leading up to Old Mill. HISTORY: Torr Vale Mill was built as a water-powered cotton spinning and weaving factory c. 1790. The present Old Mill probably served the now demolished water-powered spinning mill as a handloom weaving shop. The site was enlarged and remodelled between 1860 and 1879, and new spinning and weaving buildings erected, the former incorporating the basement storey of the earlier spinning mill which housed its water wheels and wheelpits. These were used in tandem with a newly introduced steam engine to power the site until the 1940's. Torr Vale Mill is a near-complete example of a multi-phase integrated cotton spinning and weaving factory, which retains extensive evidence for both water- and steam-powered phases of manufacture, buildings which represent each stage of the development chronology of the site, and examples of both fire-proof and conventional timber-floored construction. There is also clear evidence of manufacturing processes and power transmission having been adapted to the constraints of the steeply-sided valley it sits within. As such it represents a remarkable survival, its significance enhanced by the fact that it has remained in continuous use for textile manufacture from the 1790s.
