I have a 7′ deep crawl space on the front side of the house. It is accessible with a 5×5 sliding gargage door. I am planning on converting the space to a workshop. I am going to put a concrete pad and plan to wall off the remaining crawl space. I will end up with a 12×24 foot room.
My question is how should I build the wall that separates the crawl space from the new room. I planned on putting it on the concrete pad. Do I need to pour a foundation under the wall? Also I assume I should use treated pine for the studs. Fiberglass batting with wall board on the interior would finish out the wall. Please critique this plan and provide any suggestions.
Thanks!

You only need treated lumber for concrete contact locales so a terated plate will be enough unless the studs themselves will be in contact with the concrete. I f the structure is already there you dont need a foundation under the wall as it will be a partition wall only. That is to say it won't be carrying any structural loads. Pour the pad and build your wall on top of it using a treated plate on the bottom. Regular KD lumber will do from there.
