Finally Starting To Plan A Garage(need some wisdom)

[bobthecop]

I am also wanting to build a shop, I live on 5 acres, so I have lots of room. I wondered the difference in price from a 30X40 to a 40 X 60. and is pole barn type construction as good as steel or regular house type framing?? and how much will it cost for the concrete floor. I am able to do a lot of the work myself, minus the concrete and plumbing. This is going to be a pay as I go project, kinda like my truck, I stay out of debt.
