Welcome from the Missouri Ozarks, USAF retired. I'm in my 5th shop, was the general contractor or built them myself. This one is the largest, about 2500 sq. ft. and stick built. Block is hard to insulate unless you build another wall inside. This shop starting from the outside is metal, chip board on 2 x 6 studs with 6 inch insulation and more chip board on the inside walls. The ceiling is also metal with 24 inches of blown-in insulation on top. Has three bays and a large heated and air conditioned room larger than a bay on one end with a bathroom. One bay is set up for a lift, plan on a 4-post, concrete is 5 inches thick in that bay and the ceiling is 14 feet. I also have portable heat for any bay I'm working in when its cold. Building has standard trusses with 3/4 inch chipboard with the metal roof screwed to the chipboard. So far it has survived 80 mph winds without problems. Two of my past shops were block and two stick built. Will do my best to answer any questions.
