Natural Ground Level Built Up

What do you do when you build up ground level a little too high and your boundary wall is so low a car could flip over whilst maneuvering up the driveway? You add a bit more height to the wall, of course!

My reading of the architect plans show that the difference in height from the front of the house at street level  to the back wall should be 700mm. It is far more than that, but I am a layman, what do I know -- the levels are correct I have been told by Council and Pitt + Sherry for the last 6 months.

What I find amazing is that they were building pyramids 3000 years more accurately than these Units at Bathurst Street.
