First course is done!! Finally! I think I’ll have a cider to celebrate :)
Pretty happy with the position of the container end of the wall too - not more than 20mm from the end block to the edge of the slab.
There is one problem to resolve however - someone (i.e. me) placed the footings for the container too close to the cutting wall, so one container door is going to foul on the retaining wall and not open very far. Not too big a deal, as ultimately I’ll just remove it.
