Historic Fraternity/Sorority House Floor Plans?

[DTD Alum]

This is admittedly a question out of the far left. I am an alumnus of Delta Tau Delta fraternity, and throughout my entire life I’ve had a strong interest in historic houses, particularly from a design standpoint. In fact, I work in real estate and do independent research on historic structures on the side. I was wondering if it is at all possible to obtain floor plans of some of the Greek houses at schools that are known for their huge fraternity and sorority houses (like Ole Miss, UT, Indiana, Washington, University of Southern California, Bama, etc). I’ve seen a couple online, but they were for new construction…I’d love to see the layout for some of the older homes that have been added to over the years. The “holy grail” so to speak would be floor plans that show the additions and renovations to the original structures over time, particularly if the home at one point served as a historic house.

Does anybody know of a possible way to acquire some of these? If you work for nationals and have an idea of who to contact, feel free to PM me and I’ll give in-depth information about my identity, intentions, etc. I’d also be willing to give a small donation to the housing fund to cover the scanning or digging required.
