 The venture was profitable, and a new theatre was built in 1856, of unprecedented size, seating 1,500.In order not to interrupt the flow of profits, the theatre was constructed around the walls of the 1852 hall, and when it was complete, the old building within was demolished in a single weekend.This new theatre was the first purpose-built "tavern music hall" and opened in December 1856, as the New Canterbury Hall.
