I agree with what everyone else has said. So many things go into it that it is hard to get an exact price. Some of these things are aesthetic and others are required by code. I know that our house at Indiana was almost double the original estimate because the university, who had final approval, did major changes to the final plan. Looking at the new construction at FSU, the houses are going for ~$3.5 - 4 million. The Pike house is expected to be 40,000 sq. ft., house 58 men and cost ~$4 million.
