There hasn't been much progress on our terrace today ... a couple of stones have been moved on top of the wall and the railing is now leaning on the fire hydrant (rather than laying flat on the ground in front).
Lots of progress on our neighbours' wall to the right, though.
What should be happening is that stones are removed a couple levels down and then put back more sturdily and then more stones added to make the wall higher. A lot of our neighbours' wall was removed ... it must have been in weak condition.
I wonder if they'll have to do the same with ours.
