I think my fortress is unique in that I apparently should have forged some coins or ... something. The point is that because my in-game progress has retarded, I've been able to build out in other ways. I've attached a map of my fortress below.
Things to note:
* This is my first fortress I managed to survive the winter with, so go easy on me. I just now realized this setup won't work once I make coins/get a bookkeeper as I'm wide-open.
* Most everyone gets a 3x3 room at least--many get 5x5. After seeing everyone else's rooms, I think I'm going to shrink down to 2x3 max unless my dwarves deserve a larger room.
* I think I am way too open on the lava side. Apparently you guys have problems with monsters? I have had 3-4 runins with Fire Men, but nothing I can't handle.
* I am a big fan of Nile-style farming. If you start with two good miners like I did, you can build out huge farming tracts for the same amount of effort as a smaller mechanism/lever-based setup. I understand that lizardmen are annoying (I have been attacked 6+ times by lizard/snakemen), but...who cares? Build a Nile-style farm early, and seal off the area if it's too dangerous...I guess.
* I was early in the process of building a lava moat around my base (until I came here and realized my fortress setup isn't viable). Is it possible to build a bridge over a (lava) canal? If so: awesome.
Without further ado, here's the fortress:
