Alright, I want to do some mega-constructions, but in the interest of consistency I want them to be made entirely out of simple materials
So what I'd like is a relatively flat embark, 3x3 or so, with access to sand or clay and a surface magma tube, preferably as close to 'ground level' as possible. I wanna build a big awesome castle, basically.
I have a good one for you, I've used to for two projects so far and it's pretty decent.

Embark Location:
Prospect shows native copper, cassiterite, sphaleritie, gold and marble. Black sand and fire clay are abundant, making up the entirety of the soil layers. The magma tube is directly in the middle of the embark, and magma is only one z-level away. The whole area, except the north to north-east corner is flat, and what isn't flat is only 2-3 z-levels in elevation.
There are quite a few megabeasts hanging around, lots of goblins, and a necro tower close by, but if you are only concerned with buolding you can always turn invasions off.
