McDonald Jones Homes NSW, Baulkham Hills (Sydney Office) Questions & Answers

I have got 357m2 land in Schofields and looking to build double story with budget $270k to $305k . Please advise me. Thanks

I am doing a tender with McDonald Jones. But currently holding the consolidated tender because of other builder's unethical and unprofessional act. The other builder with its office at Spring Farm is building a house on my neighbour's lot and during their build they are illegally using my land. Both the builder and owner did not contact me for the use of my land. Without any permission from me, they used my land to deposit a huge pile of soil, mix the concrete, drive and park their vehicle, put a building fence halfway through my property. They increased slope of my land to level it with their block affecting the original gradient of my land. Upon speaking with the Site manager, he advised that he did it to save the unnecessary cost to their customer as their customer's land was sloped. He initially assured me by email that they would return my land to original state. They removed the the building fence and partially removed the spoil from my land, but deposited and spread out huge soil on my land to bring it to the level of their customer. The builder is now not receiving my calls, not responding to my emails and message.
The other builder did not care about the neighbour's property. They illegally used and damaged someone's property for their own benefits. They tried to save their own cost but did not think about the negative impact and additional cost to their neighbor.
I have reported this to council, but council advised me to resolve this internally or go to local court. Council is not helping much, about which the builder is very much aware as he said to me "Council does nothing". Thats why the builder is trying to take the advantage of this. The builder is completely negligent as the site manager thinks this is normal in building industry to use someone's property. In my case, the builder not only illegally used the property, but also damaged my property as the slope of land and contour has been completely affected because of the excess spoil being deposited on my land to make the same level to their customer.

Is there any legal process to action against the builder for illegal use and damage of property or I have to go to local court as advised by council? Is there any builders forum where I can report about this builder? My build is delayed and affected because of this builder's negligence and I am mentally stressed.
