To ensure the brick columns are still vertical in the future, you MUST have decent footings! The footing must be large and deep enough. You'd better to have an engineer to provide a footing section detail prior to construction.

I think my neighbour's pillar footing is 600x600x250. If you have type S soils or similar with clay content then you need upgraded footings.

Other important things to do:
- Use N25 concrete etc.
- Place some Y12 REO in the footing up the centre of the pillars and core fill with concrete.
- Chuck some trench mesh in. This is required just in case there is a water burst which will cause soil subsidisation. The compaction loss will cause the wall to sink somewhere resulting in a crack.
