Your PM is doing you a disservice re the presales, get a second opinion.
It sounds like you got a DA for the whole site when you prob should have got a DA for rear lot and then a separate one for the front. Did the PM advise you to do the whole lot at once? Did they know of your intention to do the development in 2 stages?
Yeah they (PM) knew it was always our intention to build on the rear first. However they also made it clear to Council that this was our plan. I don't know how they made this clear but I understand they've got a good working relationship with the council. However on all the applications it was always for 6 units.
However if they made Stirling know they must have also made the WAPC know as they(WAPC) are letting us do it in stages.
