Category B listed colliery winding group comprising a c.1968 steel headframe, capped shaft and c.1896 steam winding engine and engine house within Highhouse Industrial Estate.
This record has completed the HAABase Mines source-by-source fact-checking process.
The history, timeline and surviving-site classification shown here reflect the reviewed account.
The record identifies this site as Highhouse Colliery at Merlinhill Farm, Auchinleck, and distinguishes it from the nearby Barony Colliery and from other Baird-owned pits around Lugar. The surviving site is the winding group within Highhouse Industrial Estate: the c.1896 brick engine house and Grant, Ritchie and Company steam winding engine, the c.1968 riveted steel headframe and the capped shaft. The history is supported principally by Historic Environment Scotland's official listed-building and national site records, East Ayrshire Council planning documentation, contemporary reporting of the 1908 fire, museum material and established specialist mining and railway-history sources.
The evidence establishes development in the mid-1890s, the surviving winding engine's date and maker, the 1908 fire, National Coal Board ownership, replacement of the wooden headframe about 1968, closure in 1983 and Category B designation in 1992. Uncertainty remains over the exact year in which sinking began, the precise early shaft measurements and parts of the older beam engine's multi-site provenance. Claims concerning Dorman Long headgear, an underground connection with Barony and a fatal roof fall in 1906 are not included in the historical narrative because sufficiently specific evidence has not been identified.
The core site history and all retained timeline events have high evidential strength, with qualifications applied to the early development and machinery provenance.
The surviving site comprises a capped shaft, the riveted steel headframe erected about 1968, the brick winding-engine house dating from about 1896 and its in-situ Grant, Ritchie and Company steam winding engine. It is classified as a repurposed site with a headframe and associated buildings because this compact colliery group remains within an active industrial estate where some former mine buildings were adapted to later uses. Its authenticity is mixed: the engine and principal engine-house fabric belong to the late nineteenth-century colliery, the steel headframe is an original operational replacement for an earlier wooden frame, and the engine house has later brickwork, roof alteration and inserted openings.
The former wider colliery has largely disappeared. Historic Environment Scotland designation LB6580, the national site record and East Ayrshire Council's planning documentation support the identification and surviving-site assessment. The classification does not imply that the full historic colliery complex survives.
Highhouse Colliery was developed by William Baird and Company at Merlinhill Farm near Auchinleck during the mid-1890s as part of the company's Ayrshire coal and ironworking operations. Sinking created two shafts, reported in specialist accounts as approximately 177 metres and 174 metres deep. A two-cylinder horizontal steam winding engine made by Grant, Ritchie and Company of Kilmarnock was installed about 1896.
A serious fire affected the engine-house area in July 1908. The colliery later became part of Bairds and Dalmellington Limited and passed to the National Coal Board at nationalisation in 1947. About 1968 the earlier wooden headframe was replaced by the surviving riveted steel structure, whose dog-leg raking struts span the engine house.
Highhouse closed in 1983 and the site was adapted as Highhouse Industrial Estate. The steam winding engine, brick engine house, steel headframe and capped shaft remain together in situ and were designated as Category B listed building LB6580 on 4 September 1992.
Highhouse Colliery was established at Merlinhill Farm, south of Auchinleck station, by William Baird and Company during the mid-1890s. Specialist records place the start of the colliery between 1894 and 1896. Two shafts were sunk, reported as approximately 177 metres and 174 metres deep, to work coal in the Ayrshire Coalfield as part of Baird's extensive mining and ironworking interests around Lugar.
A two-cylinder horizontal steam winding engine made by Grant, Ritchie and Company of Kilmarnock was installed about 1896. The engine remains in its original engine house. Historic Environment Scotland records cylinders approximately 0.5 metres by 1.22 metres, a later winding drum approximately 3.03 metres by 2.01 metres and Stephenson link motion. Highhouse also employed an older beam engine for haulage. Traditionally attributed to Walkinshaw of Bridgeton and dated to about 1790, it had previously served at other workings before reaching Highhouse in the 1890s. It ceased working there in 1956 and was subsequently transferred to Heriot-Watt College for preservation.
A serious fire broke out in the engine-house area on 30 July 1908. Contemporary reporting identifies Highhouse coal pit and William Baird and Company directly, and the damage led to substantial repair and rebuilding. Highhouse continued as a producing colliery through the first half of the twentieth century. In 1931 it became part of Bairds and Dalmellington Limited following the combination of William Baird and Company with the Dalmellington Iron Company. It passed to the National Coal Board when the coal industry was nationalised in 1947.
The earlier wooden headframe over the winding shaft was replaced about 1968 by the structure that survives today. It is a riveted steel frame with two pulleys side by side and distinctive dog-leg raking struts arranged to span the engine house. Historic Environment Scotland describes it as probably the last traditional headframe built in Scotland.
Highhouse Colliery closed in 1983. Its wider surface complex was subsequently reduced and adapted as Highhouse Industrial Estate, but the winding group remained in place. The surviving engine house is a single-storey brick building with later alterations to its upper walls, roof and openings. It retains the c.1896 Grant, Ritchie and Company winding engine, while the c.1968 steel headframe stands directly above the capped shaft.
The engine house, winding engine and headframe were designated together as Category B listed building LB6580 on 4 September 1992. The designation identifies the engine, apart from the example at Lady Victoria Colliery in Newtongrange, as the only steam winding engine in Scotland remaining in situ. Together, the engine, building, headframe and shaft preserve the principal winding arrangement of Highhouse Colliery within the later industrial estate.
