Now wondering if possible to build a shed on those concrete blocks
that just about sit on the surface. The blocks probably weigh 50 lbs
each, and are shaped on top to fit four by four post or cross member.

They are sometimes used here to support a deck or patio.

Considering a simple wood frame shed approx. 12 by 20 sitting on nine
of those blocks, about six inches to one foot off the ground, with
possibly an insulation pad below each block to slow freezing and
heaving of the ground.

Advice/comment welcomed.

No problem with our 12'x16' shed that just has the 2x6 floor joists
sitting on a bed of gravel. No footings at all.
The asphalt driveway that butts up to the shed actually lifts with frost
to where the double 4' wide doors could not be opened. I had to cut a
half inch off the bottom of the doors.

On my mothers house the stucco was done after the paved driveway. One
really cold winter the driveway heaved up a couple inches. The stucco
had no place to go, so it folded and cracked all over. It was so bad
the entire wall was redone... on top of the driveway again! I told her
not to pay but it was too late. 2 or 3 years later the same thing
happened although not nearly as bad. This time the blacktop was cut an
inch or so away from the house, the driveway heaves and it goes down
again in the spring. No more problems.
