Backstage Academy, which runs degree level courses in the creative arts, submitted plans to convert Waterfront House on Thornes Lane to expand on the number of courses it offers.
The plans include creating 74 new bedrooms, half of which would be en-suite, and retaining the existing car park which has 28 bays.
Office space and a reception would also be developed as part of the proposals.
Wakefield Council’s planning and highways committee approved the plans at a meeting yesterday.
Backstage Academy has links Wakefield Theatre Royal and Wakefield College.
