The growth of Florida's public universities was a key issue during a meeting of the Board of Governors on Thursday.
State university system chancellor Mark Rosenberg says a quarter of the system's current classroom, lab, office and study space was built in the late 60s and early 70s.
Now, the growth of Florida's college enrollment has surpassed the growth of many campuses.
Students at Florida State University say the lack of growth is really felt at the start and at the finish of the semester.
"I personally had to change classrooms this semester because we had too many people in our class. We had to move to a bigger classroom, because if you come in late you didn't have anywhere to sit," said FSU senior Nicole Tierney.
The system expects an additional 50,000 students by the year 2012 and says the state will need another 14 million gross square feet of facilities, at an estimated cost of $3.4 billion.
