My brother in Oklahoma is getting into woodworking. Unlike my situation with the proverbial tract house, bro has ten acres where he wants to build a workshop. I suggested going with a steel building. He insists steel is very expensive and it would be cheaper to build a wood framed shop.

While I was pretty sure steel was less expensive, I admit I'm no expert. For anyone who has built a shop recently, what's the real deal? Is a steel building actually more expensive than a wood framed building sheeted with OSB and vinyl siding, for example?
