Also known as Trafalgar Studios at the Whitehall Theatre in honour of its former incarnation, the building consists of two intimate theatres designed by architects Tim Foster and John Muir. Studio 1, the larger of the two spaces with 380 seats, opened on 3 June 2004 with the Royal Shakespeare Company's production of Othello. Studio 2, with 100 seats, opened in October 2005 with the play Cyprus.
The original Whitehall Theatre, built on the site of the 17th century Ye Old Ship Tavern was designed by Edward A. Stone, with interiors in the Art Deco style by Marc-Henri and Laverdet. It had 634 seats. The theatre opened on 29 September 1930 with The Way to Treat a Woman by Walter Hackett, who was the theatre's licensee. In November 1933 Henry Daniell appeared there as Portman in Afterwards. Hackett presented several other plays of his own before leaving in 1934, and the theatre built its reputation for modern comedies throughout the rest of the decade. During World War II it housed revues, which had become commonplace entertainment throughout the West End. In 1942, The Whitehall Follies, featuring Phyllis Dixey, the first stripper to perform in the theatre district, opened with great fanfare and became an immediate success. Dixey leased the theatre and remained in it for the next five years.
A series of five long-running farces, presented under the umbrella title "Whitehall farce" by the actor-manager Brian Rix, were staged at the theatre from 1950 to 1966: Reluctant Heroes, by Colin Morris (1950–54); Dry Rot, by John Chapman (1954–58); Simple Spymen (1958–61); One For the Pot, by Ray Cooney and Tony Hilton (1961–64); and Chase Me, Comrade, by Cooney (1964–66). Excerpts from the shows were televised by the BBC.
In 1969 a nude revue called Pyjama Tops took over the venue and remained for five years, after which the building was shuttered until July 1982 when a production of "Private Dick" starring Robert Powell ran for 16 weeks. After considerable refurbishment that retained most of its Art Deco features, it reopened on 5 March 1986 with a successful revival of J.B. Priestley's When We Are Married. Subsequent productions included When I Was a Girl I Used to Scream and Shout, The Importance of Being Earnest, The Foreigner, Run For Your Wife, Absurd Person Singular, Travels with My Aunt, tributes to Patsy Cline, Roy Orbison and the Blues Brothers, and solo performances by Ennio Marchetto and Maria Friedman.
