Bosses at the Manchester Road theatre want to breathe new life into the basement level of the building.
Members of the public are being asked to complete a survey in order to help with the application.
The survey can be found at www.surveymonkey.co.uk/r/2VLJS7Z.
Hard copies are also available from the theatre.
