A couple of years ago we did some major foundation/structure work to our house. We were going to tear down the small 2 car garage and add a three car. I planned to use the trusses from the old garage to build a new work shop at the back of my 1 acre lot. The house mover who we were using to hold up the existing structure while a basement was added asked "what are you going to do with the old garage?" After a bit of review, he moved the old garage to the back of the lot onto a new pad that gave me an "instant" new shop. Though it was smaller then I would have liked (never big enough", watching him move it made me so glad I had him do it.
Use an experienced house mover, they know what they are doing, and sitting with a beer in hand is the best of all!
