Privately-run Futureworks Media School has invested £100,000 to increase its capacity and taken 3,500 sq ft at an adjacent building on Dickinson Street in Manchester.
The space provides extra room for Futureworks' games department and administration unit.
The college now measures 17,500 sq ft with studios and equipment available for students on year two and three vocational media courses.
The remaining space at the college, located at 87-89 Mosley Street, will house the film, television, and audio departments.
Chris Mayo, managing director at Futureworks, said: "The shortfall in university places has meant that increasing numbers of students are realising the career opportunities that come with more vocational courses. At Futureworks, our courses are delivered by industry-expert tutors within cutting-edge facilities and the existing space we had just couldn't satisfy the demand we have been seeing for this.
The college has increased its capacity from 250 to 400 students.
Futureworks said the building on Dickinson Street has been leased from a private landlord. Knight Frank was the letting agent.
