Historic Fraternity/Sorority House Floor Plans?

I'd suggest checking with the school's directly. My undergrad's Special Collections Library had plans/blueprints for all the buildings on campus. If the school has a "University Archivist" that would be a good person to ask; there are materials that aren't placed into the online catalog but are accessible if you have a reason to or ask nicely enough. The longer the person has worked there the better.
