I recently moved from NY to Tn. I am building a pole barn to work out of, store stuff and tinker around in. I do carpentry for a living. I have some hit and miss engines, generator's, and small engine stuff. How would you build your barn?. I have already started. 24 by 30, with a 10 ft ceiling height. I will be pouring a concrete slab in the next couple weeks, the barn framing is already built. I will need heat and air conditioning, if I am going to enjoy tinkering in there in the hot or cold weather. Tennessee is a warmer climate, should I put pex tubing in the floor for heat? could I then run cold water, via an old drilled well ( not in use anymore) for cooling in the summer.? This will be a several year project, completing it as money allows. :crazy: obviously I will have to insulate it before trying to heat or cool it. I will put in my dust collection system and lots of electrical outlets, and maybe even a small section to set up the little mig welder safely. Any arc welding I will probably do outside. Any thought on what guys you have done or would do would be cool.
