In the building designed by Scott, the theatre had a proscenium-arch stage, and a seating capacity of about 1,400 people, on three tiers (stalls, circle and balcony). Two tiers of seating were later added to the side walls of the theatre and the stage extended beyond the proscenium, by means of an 'apron'. Balcony seats could only be accessed by means of a staircase to the side of the building, separate from the main foyer and bar. The theatre has several notable Art Deco features, including the staircase and corridors at either side of the auditorium. It is a Grade II* listed building.
