We built with Rawdon Hill Homes. Excellent. What we saw is what we got and included in quoted price. We didn't have to pay for any design changes, only up grades we wanted.
They are big around Cranbourne area.
I think in the West they have been take over by Hermitage Homes, who I believe are not quite as good.
The quality of Rawdon Hill has been fantastic. Our home was built in 3mths.
One thing I remember when we built was the price difference of the slab that needed to poured. It depended on soil type and alot of people got caught out and had to pay extra for a certain type slab after the soil testing had been done (think H class was the more expensive??).
We were fine and warned of this and in fact the correct slab was quoted in our original quote.
Good luck with it all.
