If you can get to it with a truck you could probably move it with a roll back. That's how I got my shed. It's 10 x 14
I helped move a 12 by 12 wood utility building about 11 or 12 feet tall built on 2 x 6 headers and joists and 2 x 6 treated flooring. We loaded it on a roll back and it was obvious that it could turn over the truck, so we then jacked it up higher and backed a heavy equipment trailer called a 'low-boy' under it and pulled it with a heavy dump truck over a rather uneven yard and down the road. Weight is not much of a problem with a 'low-boy' as they are used to haul bulldozers!
