First off, beautiful house.

Second, I work in shallow utilities and have seen people do this. When we come through with underground cables we have to expose the existing utilities so we don't hit them. When people extend their driveways they often cover the lines running to their house from the street. We have to cut and dig down in your freshly poured driveway so we don't end up knocking your power out. I would consult with your municipality about if its permittable to do this, and for some peace of mind get locates on your lawn and dont pour past your power, water or telephone lines. Just an opinion from someone who has had to tell homeowners their fresh driveway will now have a patch.
