Clemson has two separate building structures set up for Greek housing on-campus. There are two buildings that are four stories each and hold three sororities each, with the bottom floor holding a large open meeting room and three smaller rooms designated for each chapter as well as a laundry facility room. The other six sororities and some fraternities live on the Greek Quad, which is a bunch of four-story buildings with a similar setup.
Here are some links to the housing website, and I can answer more questions if you have them:
