There are nearly 2,700 seats in this facility. The Opera Theatre is the venue for Opera Australia and seats a bit more than 1,500 patrons. The Drama Theatre (544 seats) offers plays by the Sydney Theatre Company, and The Playhouse (398 seats) is a slightly smaller auditorium for the same purpose but with a different configuration. There are also two smaller halls — The Studio (400 seats) and The Utzon Room (210 seats) — for chamber concerts and other such entertainments. The Sydney Opera House Trust in late 1990s started to communicate with Jørn Utzon to result reconciliation and for securing his future involvement chances to the building. The trust appointed him as a design consultant in 1999. The Utzon was renamed as “The Utzon Room” for showing honor to him in 2004.
