A temporary theatre which has housed Shakespeare productions while two other theatres are redeveloped could be open for an extra two years.
The Royal Shakespeare Company (RSC) plans to apply for planning permission to keep The Courtyard Theatre in Stratford-upon-Avon open until 2012.
Full performances in the Royal Shakespeare and Swan theatres are due to be held in 2011.
The Courtyard Theatre, which seats 1,000 people, opened in summer 2006.
The RSC said it was likely to submit an application to Stratford-on-Avon District Council's planning committee in September this year.
The Courtyard Theatre was established at the site of The Other Place, the company's small studio theatre, which the RSC said it would reinstate as a 200-seat space.
It added the project for the transformation of the Royal Shakespeare Theatre was "still on time and on budget".
The RSC said it was planning to open the theatre in late 2010, following its closure in 2007.
"Preview events" would be held ahead of full performances being staged during a "measured move" back into its new home, the company said.
