Yes the walls finished. Window height is all I've picked and I did that at 42 inches just in case I wanted benches on the side but I want the bench on the back wall. One priority is my Klipschorns which have to be placed in the corners for bass response, silly as that sounds. As far as conduit not sure but if overhead outlet added I think I want that in conduit. They are already having to relocate my H frame and put all electrical boxes on the side of shop (preferred anyway) because of set back of 30 feet conflicted with original plan so don't know how much I can ask for w/o change order, want to figure out what I want and see where it lands. Thanks again, I really appreciate your input!
