My neighbor Lopez had a shed delivered like this a couple years ago, but it was about 40' long. It was the first time I'd seen it done. Really nice building, prewired and the works.
I'd like to get ahold of a 20' cargo container ahd have it put behind my shop. I don't know if they can move those like that though.
