XWXThis will give each dwarf a bed(b), container(v), and cabinet(h). I think those are the characters for the shortcut menu, anyway. Walls on the sides, up/down stairs in the corners, repeat until you run out of room.
Assuming a 38X38 buildable area, that's 19 rooms across, and 9 down, 171 rooms per floor, 513 rooms on 3 floors. The rooms on one side won't have an outside wall unless you use bridges, and there will be an empty buildable tile along the bottom (or top).
This doesn't include rooms for
lever pullers deadbeats nobles, who should probably have their own floor on the opposite end of the fort. Hmm, dorfs in the bottom 3 levels, nobles on the top level, columns of empty space between them, and a few 'special' levers for the dorfs entertainment...yesssss, this could be veeerrry entertaining

. Except for the 3 FPS issue
