The younger Wilkins, responsible for Downing College and London's National Gallery during his career, designed a new theatre nearby to replace the 1807 building.
[6] On his father's death in 1815, Wilkins inherited the leases of the new site and six other theatres – Norwich, Bury St Edmunds, Colchester, Yarmouth, Ipswich and King's Lynn[7] – and continued to run them.
Proprietorship passed to his son, W Bushby Wilkins, and a succession of lessees, but the Norwich circuit declined, despite hosting readings by Charles Dickens.
The interior was modernised, with the proscenium arch widened by the removal of the private boxes,[10] and the introduction of electric lighting, a brick cyclorama and an early example of a revolving stage.
Herbert M. Prentice was also involved with the theatre; in April 1927 he directed George Bernard Shaw's Androcles and the Lion there.
[13] Historic England describe the interior as "a virtually complete example of a Georgian theatre with a three-tiered horseshoe auditorium with the galleries supported on cast iron columns."
