Eglinton Engine Works, 25-27 Cook Street, Glasgow

The Eglinton Engine Works, located at 25-27 Cook Street, Glasgow, were built from around 1855 and demonstrate significant group value as a substantial industrial complex. The main block on Cook Street is a three-story, fifteen-bay ashlar building, originally serving as a fitting shop and later a machine shop; it is now used for storage, a canteen, and offices. The front and sides are constructed from ashlar, while the rear is brick. The building has ten-pane windows with stone margins, and two ground-floor windows now contain doors, with one large arched doorway blocked. An eaves cornice sits above a slate roof. Two eastern bays were originally offices, separated by a brick party wall and chimney.

The western portion of the building features a three-story structure with cast-iron columns and square-section fittings for shafting, supporting rivetted wrought-iron beams that likely replaced earlier timber beams. Seven bays between the office section and the arched front doorway originally housed a high-ground-floor fitting shop with iron stanchions and a gantry. The third floor was a finishing shop.

A former lodge building, approximately dating from 1870-1880 with later additions, stands east of the Cook Street block.

A single-story, one-bay brick engine house on West Street, built around 1855, originally powered the entire works. It features an arched, fanlit window and a slate roof. A four-story, nine-bay brick block of circa 1855 adjoins it. This block has arched ground-floor windows with keystones, yellow brick margins, and iron frames. A large arched doorway has been filled in. The upper floor windows feature sixteen-pane iron-framed glazing, yellow brick lintels, and stone cills, topped with a slate roof.

The ground floor of this West Street block initially served as a smithy and boiler room, later converted into a weighing-machine shop. The first floor was used as a pattern maker's shop. Iron columns with square-section fittings for former shafting support wooden beams and floors. The upper floors were used as pattern stores, featuring stout iron columns and wooden beams. To the south, brick fronts face two machine shops; one from 1866-8 is two stories high with large arched metal-framed windows, a stone cornice, and a parapet, fronting an erecting shop. An adjacent boiler shop dates from 1874-5 and has four arched windows and a large arched doorway with ashlar keystones and original timber doors, surmounted by a stone cornice and a brick parapet. The south wall is brick, buttressed with large arches and oculi, some of which have been filled in.

The complex's internal layout is comprised of five distinct workshop areas. The light fitting shop features steel stanchions and a modern roof covering a former yard, bordered by the front blocks. The heavy fitting shop, formerly a general shop, has five tall H-section stanchions supporting a rail for a travelling crane, two of which have jib cranes attached. The south wall has brick relieving arches from circa 1868, some pierced, with an iron rail above and a thinner brick parapet with oculi. A wide kingpost timber roof covers the space. The heavy machine shop, formerly the Erecting Shop, has a brick arcade with oculi on the north side, plain brick buttresses on the south side with two arches (circa 1868), and a kingpost timber roof. The light machine shop, formerly the Boiler Shop, similarly features a north wall with plain brick buttresses, a south brick arcade with oculi, a kingpost timber roof from 1874-5. The fabrication shop, formerly the smithy, retains a corbelled brick arcade with oculi, part of which is visible from West Street. A railway runs north-south through the engine works. Remnants of shaft supports are visible within the walls.
