what is the actual size of the barn??
Can you tell if there are timbers at the bottom of the walls(the sills)??? If the sills are there and in good shape, it may be possible to move the building... if the sills are looking rotten, you are most likely out of luck or the sills will have to be replaced before moving.
Are there power lines in the way?
Talk to a house mover in your area for the real storey.
This post would have been better in the barns and traditional timberframing forum.... I think it may still be possible to move it over?
