We have just been quoted a P class slab for our block of land which has a 1.2 metre fall from front left corner to the back right corner and additional site costs for the following. (Yet to receive a breakdown of the house price with the standard site costs)
Cost of Site cut and possible removing soil from site approximately including 10% GST is $17,500.
Estimated Engineer design Sleepers Retaining Wall required is 36Linear meter up to 1.0m high at a cost of $14,500.
Does anyone know if this is about right or if its a little extreme?
