Suggestions on building a garage in central Fl.

Mine is nowhere near that size, mine is only 22x22 with 8' walls. But what i did was wait and hunt around and I found an older house that was going to be torn down for a new development and the garage was for sale. Bought the garage for $500. My dad and I formed a pad, hired someone to pour and finish and then paid a house mover to move it. All in $5k, no hydro or heat, but i figure i saved about 1/2 the price if not more and it was done in a matter of a week. All depends what you want for a garage. Mine is jam packed and wish I had twice the space, but I am financially challenged. Good luck!
