Thinking on a new pole barn

As you may have seen in chit-chat, we are building a new home.

Part of the project, as finances allow, will be a new pole barn.

Thinking on 28'x48'x12' to eaves.

Neighbor is building a pole barn framed as any pole barn would be, except it is being built on a "floating slab" and the poles set on the slab, instead of being planted 3'-4' in the ground.

Just wondering if any of you have seen this type of build, or have any experience with it.

Looking for thoughts and/or opinions on the pros & cons of one method versus the other!

As I sit here and think about it, I suppose the "on top of slab" construction would be just as stable as a conventional stud wall sitting on a foundation.

Thanks,   Dave
