There are 1 or 2 frame obs hive that are for temporary viewing. They can last a day or two in there closed up, with a feeder a few extra days. Beyond that and you'll end up with a new queen, or things can go downhill quite fast if they are cooped up too long.
As far as what's available...I'm guessing that with a TBH you'll have to customize something. There are plenty of free plans available, I built mine from
http://www.beesource.com/plans/obsrhive.htmYou can customize the width, height, make doors on it, etc. I did a little bit of customizing to make mine a full time obs. hive but portable as well.
