Well, some half formed thoughts....
If what you want is an addition to your house, then it feels to me
like a pole building is a hillbilly approach. If you want to side,
insulate, sheetrock in a pole building, a lot of the cost saving from
not having to put in a foundation are going to be offset. Also, how is
the roof going to work? I'm having a hard time picturing how a pole
barn roof would tie into an existing roof.
Course, I can't see your house so I don't know what it is worth.
Maybe resale absolutely doesn't matter to you, but if you do sell it,
what will potential buyers think? I know I would not like to buy a
house with a pole addition on it.
I guess my second choice after frost footings would be a shallow frost
protected slab on grade. I'd talk to an engineer about it, though.
