Ah that's a bummer... Well if it's any consolation I think Blacktown is one of the quicker-to-approve councils.
In hindsight we should have lodged through council so we could have moved the house closer to the road and have more backyard, but oh well!
At least you are nearing the end of your build.
As for us our tender expired and the consequences is that they're going to review how much the price increase would be.
We'll we are just hoping it won't be that much.
Just tell them if they hit you with too big of a price rise that you will go with another builder. That should get them to be not quite so savage with the price...
