Wow, already some good input! Thanks.
Yes, the building is heated, although to a fairly low temp, like 40 degrees F.
The expansion joint idea is kind of the default plan if nothing else seems workable. for the joint, I was thinking building the house with atttached breezeway pretty close to the garage, like a foot away, and around the doorway there would be an extension that could screw to the footed breezeway side, like a large extension jamb, and a layer of foam on the side where the garage door would be.
Glad I don't live in Texas, with soil conditions like that.
It still seems that the only method of filling under the slab, inside the thickened edge, is to pump it in there, pouring it will not make it flow uphill underneith.
Jim, I wonder if, as you said, to build a foot or so away....and then use a foam surround - similar to what is used for a semi trailer seal - at a truck warehouse. This set up would allow some float and be quite weather-tite. The foam seal usually has a vinyl or a nylon covering....and I have seen various colors used. I bet a dock seal company would make one to fit your situation....and it would be LOTS cheaper than the alternatives.
I think you would have trouble putting a foundation wall under an existing floot...but I spose it's been done.
