The build

Is the infil concrete or just chippings?  Does the driveway need to reach the level of the top of the shuttering, if so thats a huge amount of building up to do.

 It’s supposed be grade 1 stone   But it’s seems to be more like grade 2. Which is what we wanted but they didn’t have   . Either way is stone and conveniently what we wanted. Yes the rest of the ground has to come up to that level at the top of the shuttering. In places it’s already there. Walk 2/3 across the driveway to the garage and it at the right high. Which blows my tiny mind that there’s that much difference.
