I turned one of the Britechester dorms into an arts building with a concert hall, practice rooms, painting area and dance studio. I tried Arts Center as the lot type but it attracted too many townies so I made it Generic with the University Student Hangout trait instead. I think if you like the idea of having playable campus buildings then turning one or two of the 3 student housings into other lot types is the way to go.
I think if you wanted to do a university in a different world, then you could just decide that's where your Britechester is, or your Foxbury, and create your own lots including a student housing and a student commons and make it look however you wanted. The only thing I'm not sure about is if a student is living in a student housing lot outside the normal university neighborhoods, do they go to class like a commuter in the same way that students living on a residential lot would do, or do you get a loading screen and get taken to the regular campus neighborhood, or does it glitch or something.
