A natural stone wall will cost around $8 to $12 per square foot based on the type of stone chosen. A concrete block wall costs $6.10 to $7.60 per linear foot.
For a wall 100m long it costs over $400 000AUS. The thing with some rock and sea walls is that they can also be built on the beach to raise residential and commercial housing as the early quote stated to protect them.
