I live in an area with sub freezing weather 5 months of the year, without insulating and if ice build up on the structure is not an issue you could try wood heat. I heat my shop(24×30) with a combination of forced air natural gas and a wood stove( the wood stove is great for all your cut-offs and scrap.I have of course insulated howevere cause if i didnt id have three feet of ice on my roof.
