Delfont Mackintosh, the theatre group owned by producer Cameron Mackintosh which owns and operates eight West End theatres, has announced plans to restore and renovate four of its theatres over the next three years.

Each theatre will be closed for a period of two-to-four months in order to complete renovations, which will begin with the Wyndham’s Theatre in August, followed by the Noël Coward and the Gielgud in 2019.

The Queens Theatre, home to the long-running hit Les Misérables, will be the last to close in 2020. Mackintosh is currently making plans to temporarily relocate the production during renovations at the venue, which has remained largely untouched since reopening in 1959 after withstanding significant bomb damage in World War II, which destroyed the entire front of house and rear auditorium.

The closure of the Queens Theatre will bring major renovations and updates to the theatre’s backstage space, as well as the restoration of Edwardian architect William Sprague’s original boxes and loges.

Delfont Mackintosh has already completed more than half of the renovations at the Novello Theatre, while the Prince of Wales and the Prince Edward Theatres will undergo renovations following the runs of The Book of Mormon and Aladdin. Renovations on the Victoria Palace were completed prior to the arrival of Hamilton.

“Having just completed the hugely rewarding but very expensive restoration of the Victoria Palace, news of the timing of these works which are necessary to ensure that my other theatres will be in tip top condition for actors, producers, and audiences, long after the final curtain has dropped on me, was not the most welcome,” Mackintosh said. “There are major financial consequences—not just the considerable cost of the capital works, but the knock on costs of closing these theatres for several months will run into many millions of pounds. However, I love these buildings and luckily my success as a producer has given me the resources to preserve their life for another 100 years—so that the show can go on and on and on.”
