I built my shop out of 4 inch styrofoam.Walls ceiling and doors. It measures 12 high x 16 wide x32 ft long. All this is in a 40 x80 pole barn. Has 2 ton monorail across the middle with two hoists. My EZ is hanging overhead . I can raise or lower or roll over to work on. The shop has two heating sustems: A 50000 btu ceiling hung forced air natural gas furnace and a wood coal 60000 btu furnace setting onthe out side and ducted in through the wall. This to burn up the scrap wood on the farm. In addition there is a wall mounted airconditioner (15000 btu) . In addition there is 5 doors in each end so I can drive through with and work on my backhoe or my 32 ft motor room. Makes a great spraybooth as there is also a 20 inch exhaust fan. Expenseve. Not really . Most is salvage materials from what I had on hand. Out of pocket was less than 800 dollars. Pictures later to anyone interested. Ray
