Self leveling deck?

I hope your wrong about the engineer certificate Joe! When I have gotten them before for small structures they have been substancially lower, I don't know if that is because they weren't complex designs or we pay our engineers less over here - keep em hungry and mean.
Or maybe they're like rabbits and we have an overabundence of em?

Hardly an issue for built up locations. Camphor may be a resilient grower, but it is also an excellent shade tree for the right area.

And yer keep the camphor tree so that i can make something out of it later on

You obviously don't have any growing in your yard. Every seed berry they drop WILL I repeat WILL want to grow. Hence that is why they are classed a noxious plant.

It already is a big old tree so it can be removed and make something or money out of it, as I said earlier.

Just a wild guess, BT. But note that load paths would be all over the place because of complexity. Wouldn't need to be designed like a space ship though. The order of the day here would be to make a lot of simplifying assumptions and design to suit them; old saying is, "When in doubt, make it stout." Lower engineering fee, slightly higher construction cost. Tell the truth, I don't think I've ever worked on anything this small, except for my own DIY.

As I said earlier, the ring pattern of the cables would likely prevent much wobbling, so round steel rods might be more appropriate than cables, which are subject to stretching (actually not stretching, but tendency to unwind looks like stretching). For adjustment, put a turnbuckle at the lower end. Thread the rod RH, and keep only the turnbuckle body and the LH piece. But also as I implied earlier, adjustment might be needed only for shallow foundations. So, I don't quite see what you gain with the suspended system.
