The refurbishment saw significant structural changes made to the hotel/theatre complex. Initially, it was suggested that the theatre be largely remodelled to a two-tier concert hall design. However, architect Peter S. Parkinson resisted this push to fundamentally alter the design of the theatre and a sympathetic restoration was instead favoured. Within the auditorium, it was found that the reinforced concrete floor of the stalls was substandard and was completely replaced. Additionally, on one of the upper levels a wall was discovered which was not supported by a beam in accordance with the building plans. The much-maligned supporting pillars were shifted back to improve sight-lines for the audience. The raked stage was replaced with a new flat one, and the proscenium arch widened by and decorated with plaster mouldings of the original arch. The pressed-metal ceiling was also replaced with a plaster-moulded copy. The sliding dome in the roof was permanently sealed, and redecorated to match its original design from 1904. The orchestra pit was also expanded and new lighting and counterweights installed.
