Check out the new web site by Professor William J. Hamblin over at THINGS UNUTTERABLE. He just posted a great post about the possibility that there was a second story on the Jerusalem Temple, and some other interesting insights. Here is the link: A Second Story to the Jerusalem Temple?.
Be sure to bookmark his site. Prof. Hamblin's work, in my estimation, is the best coming from Provo these days. He has the insight that so many scholars seek, pretend they have, and yet never achieve.
