All the buildings on the east of the Haymarket from the theatre southward were rebuilt circa 1820 in connection with John Nash's schemes for the improvement of the neighbourhood. Nash persuaded the proprietors of the theatre to rebuild on a site a little south of the old one so that the portico should close the vista from Charles Street. The main front feature of Nash's elevation in the Haymarket was (and is) a pedimented portico of six Corinthian columns which extends in depth to the edge of the pavement and includes the whole frontage. It is sometimes stated that Nash rebuilt the theatre entirely, but there is evidence that he incorporated a house in Little Suffolk Street with the theatre, removed two shops which were in front, in the Haymarket, built a portico, increased the number of avenues and added a second gallery to the existing auditorium.
