On second, much closer inspection on the brickwork, it really doesn't seem that bad, and will probably only ever be noticed by me...and maybe the neighbours who will look directly at it...
I've done a up a few photos with lines (very badly drawn ones with the mouse!), to outline the problems.
This is the circled brick in question. The mortar joins line up neatly on the right side of the brick, but it is smaller than the rest of the bricks, so the left mortar join is not in line with the rest of the wall.
Here you can see the brick in question looking up the wall, and clearly seeing how much shorter it is than the others.
This is further along the wall, and you can see the whole course has been pushed out of alignment because of this one brick.
Now, I know these bricks are not absolutely perfect anyway, which is part of the beauty of them. But, to me, this particular brick must have missed being picked out by quality control, as it is about 2.5cm shorter than all the others.
As the brick course is 5 down from the top of where they stopped, and the 'brick in question' is right at the start of the course, it would require a fair amount of ripping down to replace that one brick and fix the problem.
What would you do??
On a nicer note, bricking continued along the garage/dining wall today, and around the supports to the alfresco roof! They have erected the scaffolding ready to brick up above the laundry door and continue along the long wall where the 'problem' is. Uh oh...
