Okay, I think I have this reply **** figured out. My personal lifetime situation first: I'm 59, within a few years of retiring. My man-cave just went up in the middle of this year. I will work out the driveway approach in the next few weeks as I am sharing a driveway with my neighbor and need to work out drainage (and contractor availability). I have a 24' by 48' by 9' wall height garage. I am waiting for a licensed electrician to perform the initial breaker panel and basic wiring install. I just had a 400 amp panel installed on the South side of the house, 200 amp for the house, 200 amp for the shop. After the install and state inspection of a basic installation, I will complete the rest of the electrical install for the shop. I have worked under several licensed electricians over the years, so I am figuring on completing the electrical installation myself. I am leaning towards OCB for the walls as opposed to drywall.
