No, just length and width. That said, I love multistory rooms and grand halls. All of my fortresses have them at the expense of less desirable things such as farms or bedrooms.
I built it anyway.
They all have bedrooms, too, though.
This is because I don't have to worry about military, because I'm poor. Very poor. No metals, only stones.
Trading away stone blocks, stone crafts, etc... fun.
I need to make some big money so that I'll get sieged and destroyed.
