This week our neighbor had some brickwork laid for the start of their extension. I noticed the footings were laid were slightly uneven one end. Anyway they laid the first two courses of blocks without seemingly correcting the level by adjusting the first course onto the footings/foundations. The bricky apparently approached my neighbour and said hey dont worry about the uneven rises, the first course of bricks that goes on top of these 2 courses of blockwork from ground level up will level all this out. Should they be concerned it looks very uneven to me.
