The building, previously the Eton Avenue Hall, was reconstructed in 1890. It was equipped with a large pipe organ, built in 1888 by the London firm of Henry Willis & Sons with forty-three stops spread over four manuals and pedals.
The hey-day of the conservatoire was 1896 - 1905, when its Principal was Cecil Sharp. Arnold Bax was one of its pupils between 1898 and 1900. It was also notable for an early and celebrated production of Dido and Aeneas in 1900 by Martin Shaw and Gordon Craig.
The organ was removed and transferred to a church in Brighton in 1910. The conservatoire had closed by 1928 when the building was converted into the Embassy Theatre. The building is now part of the Central School of Speech and Drama
