This was (and is) the subway's most distinctive building – an ornate, Flemish Renaissance, late-Victorian red sandstone structure; designed by James Miller in 1896.

To facilitate its preservation, the original foundations were removed to allow the construction of a concrete box to house the expanded station and new subterranean ticket hall.

Memorable images exist from the late 1970s showing the building seemingly perilously sitting on its new foundations with the empty void of the old station underneath.

[10] St Enoch is the only station on the system which requires two escalator rides to reach the platforms owing to its deep location.

[11][12] As part of the wider refurbishment of the city's subway, St Enoch station received new glass canopies for each entrance, and an overhaul of the ticket hall.
