Statement of Special Interest
Built for A & W Smith, general engineers specialising in sugar machinery manufacture. Now Smith Mirrlees; this is the only such works still operating in the UK.
The works recently expanded over Tradeston Street. Aisles 2-4 extended by about 4 bays each are steel clad and are not included in the list. The modern offices and the southern fabrication shop are also excluded. The main rectangle survives from the 19th century. The works includes
examples of every phase in the construction of engineering works, from multi-storey blocks to brick arched shops to iron framed and late steel framed aisles.
