Bath Spa University has submitted plans for a major redevelopment of its Newton Park campus to the council.
The revamp includes new academic and social facilities for all students, plus extra specialist teaching space for creative and cultural courses.
A separate application has been submitted for an on-campus energy centre using biomass fuel.
The plans have been sent to Bath and North East Somerset (BANES) Council following two public consultations.
Vice-Chancellor Professor Frank Morgan said: "With the prospect of higher tuition fees just around the corner we need to make absolutely sure that the university experience we provide our students is of the highest quality."
He said the energy centre would help the university meet its ongoing commitment to reducing its carbon footprint.
Building work will begin in October 2011 if planning permission is granted.
Plans are also being prepared for new residential accommodation for 600 more students on campus. A public consultation will take place next year on those proposals.
