The building was formerly known as Floral Hall. It was originally built by the Opera House to house a flower market (also selling fruits and vegetables), hence the name. It was designed by Edward Middleton Barry and opened in 1860. After being used as a concert hall, it became part of the Covent Garden Market in 1887. A fire broke out in the building in 1956, after which it sat derelict. It was acquired by the Opera House in 1977 and used as storage space.
