I want to build either a pole barn or a steel building 30x40 with one 10x10 garage door. I like the idea of steel buildings because of the open height space so I could build a 2nd floor storage area. I'm in North West NJ and I see many recomend Amish built buildings? Also has anyone used spray foam insulation? I want to build a garage thats tight and easy to heat and cool. Opinions?
