Completed in 1932, it employs the classic Roman Doric order in a reserved and sober form appropriate to its function commemorating all those who served in World War I (1914/17–1918). A colonnade of paired columns screens colossal arch-headed windows above a severe rusticated basement, a scheme that was influenced by the severe design of the Louvre Colonnade.
The lobby has staircases with overlooks at each end and entrances to the main level at left.
The interior contains a grand entrance hall with a high barrel vaulted and coffered ceiling parallel to the street, with overlooks from staircase landings at each end.
Stage and proscenium
The theater space is dominated by a massive aluminum and glass panel chandelier under a blue vault, and the proscenium arch is decorated with gilded figurative sculpture. The theater has 3,146 seats plus standing room for 200 behind the orchestra and balcony sections.
During the years of Kurt Herbert Adler's general directorship, the inadequacies of the house became apparent as the season was expanded. In particular, there was a lack of office space and rehearsal space. In 1974, The Pointer Sisters were the first pop act to perform at the theatre.[3] In 1979 the backstage area was extended, followed in 1981 by the opening of a new wing built onto the house on the Franklin Street side. This gave spaces for sets, coaches, and dancers as well as more administrative space. At the same time, the nearby Zellerbach Rehearsal Hall, with a stage the same size as that of the Opera House, was opened as part of the complex which included the Louise M. Davies Symphony Hall.
In 1989, the Loma Prieta earthquake caused major damage to the Opera House. The architectural firm of Skidmore, Owings & Merrill and the theatrical consulting firm of Auerbach and Associates were retained in 1992 to oversee the building's technical renovation and a seismic retrofit. At this time additional private donations were raised for extensive technical improvements. These include:
State-of-the-art lighting system – which at the time, made it one of the most extensive and sophisticated systems in the world.
Replacement of chambers for a never-installed organ with modern restrooms, sorely needed since the original construction. The organ is not needed with the completion of the nearby Davies Symphony Hall.
An underground extension below the neighboring plaza to accommodate additional dressing rooms and backstage facilities.
