Endur said:tons of maps in the Menzoberanzan boxed set. I highly recommend it. Although I'm not sure how close they fit your description.
I've got the PDF version -- unfortunately, the maps aren't indexed, so it's a little bit of a pain to work with. (I thought I had bought a hard copy second hand, but I'll be danged if I can find it.)
There's a nifty schematic of a noble complex, for the largest drow house in Mezzoberwhatchit. The description sounds like it's a much larger compound than anything in the Vault of the Drow -- a private army of 2,500 drow soldiers?!?
Any suggestions on other maps in that boxed set?
