Wow, these houses are IMPRESSIVE! UMGirl, I really love yours!
Well I'm not in a sorority yet, but I'm rushing this fall!

Here's how it works at my school, Jacksonville State:
The sororities don't have houses (there is a fraternity row though)...but there is a dormitory they all use and each of the five sororities has her own floor. (It's like an 8-story dorm, so freshman girls are allowed to live on the top 3 floors!) If I'm not mistaken, the sisters can choose to live on their sorority's floor...which is complete with a chapter room and all! I was priveleged enough to tour Phi Mu's floor and get a glimpse of their chapter room when my family and I toured the campus. It's really neat...composites from past to present line the walls (which are painted in that sorority's colors, of course) and the letters and mascot are painted on all the windows to signify whose floor it is to those viewing the dorm from outside! It just seems like such an awesome atmosphere.
I have a picture of the hall from the outside (I took so many pics on that campus tour!

), let me see if I can't get it up on a website for yall. Check back soon!
