lil sis,
it basically all depends on what school you go to. my current school only has fraternity houses. and those are just regular houses. at my last school though, there were basically two types of houses provided by the school for both sororities and fraternities. old georgian style houses or converted dorms buildings. it depended on which one you had as to how many people were in the house. i think that the largest held 'bout 40 brothers or sisters. you can check out the site if you want. i think you can even take a video tour of the houses.
