Stirling and Gowan were tasked to design spaces for offices, laboratories, auditorium, and workshops with heavy machinery.

The workshops are located in the low-rise section of the building, in a hall with a rectangular floor plan.

The angled auditorium floor results in a pronounced wedge-shape on the building's exterior.

The building was at risk failing completely without a full fabric replacement, and it was always freezing cold in winter and unbearably hot in summer.

The project was commenced in January 2016 and successfully completed by the end of 2017, saving the building's unique architecture for many generations to come.

[6] The Red Trilogy in general, and the Engineering Building in particular, are recognized as turning points in the development of postwar modern architecture.

The Engineering Building's color and geometry are more decorative than the typical 1950s and 1960s brutalist architecture.

[7] At the same time, the Engineering Building als is praised as one of Britains high points of brutalist architecture.

Elain Harwoods book Space, Hope, and Brutalism features a photo of the Engineering Building's workshop hall on its cover.
