The campaign for a purpose-built theatre in Milton Keynes ran for about 25 years before the doors finally opened on 4 October 1999. The result was a large, modern receiving house at the heart of the new city, designed to bring major touring work to an audience that had previously travelled elsewhere for it.
The building was designed by architects Blonski-Heard, working with Kut Nadiadi and Robert Doe. The design used the building techniques and stage equipment of the day, with the aim of handling productions of very different shapes and sizes under one roof.
Its best known feature is the adaptable auditorium. The ceiling can be lowered or raised and the seating repositioned, changing the capacity from around 900 to 1,400 depending on the show. Arup Acoustics tested the effect of the moving ceiling using a 1:50 scale acoustic model, so that intimate drama and full-scale musicals both sound right in the same room.
Ambassador Theatre Group, now ATG Entertainment, was appointed as operator in 1998, a year before opening, and has run the theatre ever since. The programme has settled into a familiar annual rhythm of West End transfers and tours, touring opera and ballet, drama, comedy and a Christmas pantomime.
