Alright guys, I guess I should have described my future shop a little bit. All good comments so far. The shop will have a concrete floor 24x38 with a parallel wood floor 14x38 divided by a wall with a 12' x 10' tall door in it. The wood floor part will house wood working shop(I was a cabinet maker) with dust collection coming up through the floor, 2 collection systems in a room directly under wood shop. The concrete part will have solar heated floor a few narrow but tall windows, and main door 16' x 12' tall and a walk-thru door on each end. Welders, work benches, grinder, etc will all be mobile in this main area. Lights switched in banks on walls and ceiling. Speaking of ceilings, the wood shop will have 10' & the main shop will be 14'. Also on a side note I was a carpenter for 15 years and have built 1 crude boat previously just to make sure it was within my skill set. Thanks for your opinions, I will try to post a few pictures as I build the shop. Gonna get the foundation done then see if I have $$ to finish all the way, the out side has to be really nice since it will be 10' from my house and I don't want the house to look like a silk purse on a sows ear if u know what I mean.
