In 1929, the Gramophone Company acquired the premises and converted it into studios. The property benefited from a large garden behind the townhouse, which permitted a much larger building to be constructed to the rear; thus, the Georgian façade belies the true dimension of the building. Pathé filmed the opening of the studios in November 1931 when Edward Elgar conducted the London Symphony Orchestra in recording sessions of his music. In 1934, the inventor of stereo sound, Alan Blumlein, recorded Mozart's "Jupiter Symphony" which was conducted by Thomas Beecham at the studios.
