This morning I could get a good look at how far the brickies got last night:
Double skin, about half the final length, and almost the full height:
There will eventually be concrete between the two skins, so it will be a solid wall. The outside will be bagged, so you won't see the bricks.
Today was a beautiful day for working outside. Sunshine, no wind. But no sign of the brickies! Yesterday must have been enough for one weekend. But their tools are all here, so I guess that means they will be back some time.
