As well as redesigning the main auditorium to allow for more seating and improved acoustics, the winning practice will be asked to design new studio space and front-of-house facilities.
According to Canterbury City Council, 'the principal objective of the project is to improve the spatial flexibility of the space available in order to programme a much wider range of shows, commission new work and engage in education and training activities'.
The current building, designed by local architects Alfred and Vincent Burr, was originally opened as a cinema in 1933 before it was bought by the council and converted into a 1,300-seat auditorium.
It is thought the existing Art Deco facade will be lost during the revamp. The theatre wants to expand the building forward into an open courtyard in front of the auditorium.
The 'transformed' theatre is expected to reopen in November 2009.
