Raising retaining wall height on boundary

[herewego]

Our new block has a terraced lower level where our builder has said we will need to provide scaffolding during the house construction. Their quote for this scaffolding is over $10k!!!! And we will have nothing to show for it at the end of the build.

Options
1. We arrange our own scaffolding as the price seems crazy
2. We buy the scaffolding and then sell at the end of the build
3. We raise the roadside retaining wall to block height and back fill the entire terrace to give us greater useable land area. With a small fence on top we then avoid any safety issues due to the drop off.

Does anyone have an idea what option 3 would cost to do?
The restrictive covenant for the land development says we must get approval from Mandurah city council to alter any boundary retaining wall. Does anyone see this being a problem (we could always step the new wall inside the existing one and build from there if needed)?
Any other ideas to get around this?

Thanks
Jeff

4. Buy scaffolding and lease it to others at 10k per job.

The only tradesmen willing to work on scaffolding that was put up by the property owner to save money, are the type of tradesmen you don't want building your house.
