Building in The Hills of Carmel

Hi Guys, we have recently secured a lot in The Hills of Carmel on Galloway Road, Box Hill, NSW. My builder is going through a private certified and we are told to get developer approval on the plans from the land developer. Can you please advise:

- Who to reach out to, for approval? Is there a contact?
- Secondly, how long does it take for the approval to be granted?
- is the developer flexible with any minor changes that may not be aligned with the guidelines?
- how has the general experience with developer approval been?

Please advise as we need to start building soon and this is the last piece of approval pending.

Thanks.
Dan

You have to tell people who your land developer is first. Lend Lease? Mirvac?
