Erecting Shop And Assembly Shops, Coalbrookdale Ironworks

The Erecting Shop and Assembly Shops at Coalbrookdale Ironworks were built in 1879 and extended between 1883 and 1886. The building is constructed of red brick with white brick dressings and features a clay plain tile hipped roof with a white and red brick eaves cornice. It is a long rectangular structure with 16 bays, including an original range of 11 bays and an additional 5 bays added during the extension.

The east front has 16 large round-headed windows with white brick rebates and a continuous white brick cill band. The windows are multi-pane cast-iron with radiating glazing bars in the top panes. To the right, there is a large doorway with a sliding door at the north end. At the south end, there is a lower single-storey flat-roof compressor house.

Inside, the space is large and open to the roof, featuring timber tie-beam and collar trusses supported by steel struts, ties, and braces. The west wall contains 14 blocked arches and high-level knuckle joints that once supported jib cranes and bearing boxes for a cable drive. There is also a gantry with its rails on the walls and a railway line on the floor. This erecting shop replaced smaller engineering shops that were located at the nearby Upper Works.
