I would simplify the compost heap construction.
Not use brick.
Use 2 angle irons say from an old bed frame, and bolt those with concrete
screws to the brick.
space them about 1 1/2" apart or the size of a 2x12. Stack 2x12 for the
separation.
In many compost bins you will find this construction since you can stack as
you fill and unstack as you use the compost.
