The Edwardian auditorium was recreated from the 1950s reconstruction with the addition of a curved rail and new boxes at dress circle level, named after Maggie Smith and Judi Dench. Overhangs and ceilings on each tier were also redecorated with a recurring Sprague-inspired cherub design in carved plaster and "fifteen colours and seven shades of gold". In total, approximately 70% of the plastering in the building was redone and a new, custom-made chandelier was hung. The stage was also lowered 30cm to be closer to the audience, and 32 additional toilets were installed in a void space next door to the theatre. Additional space on every floor from the basement up was also reclaimed from a former electricity substation leased to the electric board in 1907. This allowed for more space on stage as well as additional dressing rooms on several floors, now fitted with showers. Finally, new seating was installed to improve audience comfort and sight-lines. Following completion the Sondheim Theatre re-opened on the 16th January 2020 for its first performance of Les Miserables in the 2009 touring staging.
