Lamberton Engine Works, Sunnyside Road, Coatbridge

Lamberton Engine Works, located on Sunnyside Road in Coatbridge, is a late 19th-century industrial building that forms part of a group of engineering shops and offices constructed around 1870 and onwards. The complex consists of a main single-storey range, a lower single-storey range at the east end, and a two-storey office range at the west end.

The main range is built of brick with painted brick voussoirs above arched openings. It features steel roof trusses covered with corrugated iron cladding and strip glazing. The south elevation has tall arched windows with timber-framed multi-pane glazing in the lower part of the wall, arranged in groups of two, and there are six bays on the east side that are later additions. The name "LAMBERTON" is painted above the central windows. There are cast iron band steel strip tie plates that are irregularly spaced, and the cills and eaves have a moulded brick band. An extension to the east has a lower brick part and an upper part clad in corrugated iron, with a slated roof and strip glazing. The west elevation is gabled and features glazing at two levels with round-headed windows, including six windows on the upper level and three on the lower level, along with a modern sliding door below the three northern windows. The name "LAMBERTON" is also painted above the upper windows. The gable head is clad in corrugated iron, suggesting that the roof may have originally been piended. Other elevations are obscured.

Inside, the wrought iron in the roof extends eastward in steel, with the north wall being supported on steel lattice stanchions that also carry travelling cranes, one of which has a fish-bellied design. The bay to the north features a Polonceau truss roof.

The east range is an adjoining extension of the main range, consisting of a single-storey block with a gabled end facing Russell Colt Street. It has a pair of large round-headed windows with wood-framed multi-pane glazing and a large oculus above, which has wooden louvres. The roof is later and made of corrugated iron with corrugated acrylic glazing. Other elevations are obscured, but traces of masonry are visible on part of the east front.

The office range is located to the north of the west end of the main range and is two storeys high, featuring segmental arched windows that have been altered to accommodate a new office block built between 1962 and 1963. It has a slate roof, and other elevations are obscured.
