Thanks noseall,
I looked at that way of doing it which I would imagine is the most common away but thought might look pretty chunky.
Could it be done with 2 blocks upright one either side of the wall and then the next blocks flat 90 degrees to the main wall sitting across the upright blocks (quarter block bond/overlap each side) making a smaller pier on each side but infact would be a double pier with one pier on each side.
I did also consider one up right block on one side only and cutting the bonding blocks down by a quarter to make single pier on one side but this would be a lot more work and very messy.
It would really be a choice it of what you have suggested and the double pier that I suggested unless there is a reason it wouldn't work.
