Former Dalmarnock Ironworks, 73 Dunn Street

The Former Dalmarnock Ironworks, located at 73 Dunn Street, was built for William Arrol and Co in 1871, with additions made in 1889 and later. The structure consists of a two-storey, 31-bay rectangular block, which has a four-bay return, and a three-storey block with a later attic that originally served as a shuttle factory, positioned to the right. This building is part of the remaining structures from the Dalmarnock Ironworks complex. At the rear, there is a large steel-framed workshop with a rectangular plan.

The exterior is constructed of red brick laid in English Garden Wall bond, featuring a yellow brick eaves course with a dentilled cornice on the two-storey section. The three-storey section has a moulded eaves course, a recessed glazed attic storey, and a cast-iron balustrade above. The workshop has later corrugated metal cladding over the brickwork on its north elevation. The ground floor has round-arched openings, while the first and second floors have shallow-arched openings with projecting cills. A large rectangular opening on the far right of the two-storey section includes a steel I-beam lintel and a roller garage door. The lower portion of the ground floor openings in the centre has been replaced with rectangular openings, and there is a single rectangular opening on the north elevation under the second window to the right at ground floor.

Inside, as observed in 2010, there is a foreman's office on the first floor, featuring vertical timber boarded walls leading to the workshop and some six-pane cast-iron framed windows, accessed via a replacement steel staircase. The workshop has an open, steel-framed interior, equipped with a replacement Arrol Five Ton travelling crane and post cranes. The windows are predominantly 32-pane cast iron frames. The two-storey section has a piended roof covered with grey slates, while the former shuttle factory has a flat roof. The workshop is topped with a later corrugated, plasticised sheeted roof.
