We are building with Chris Allen from Coastal Homes having seen a few of their spec homes & really liking the quality of work. http://www.coastalhomesgladstone.com.au/
Fortunately for us, new builds were drying up in the area as global credit crisis hit the building industry hard so we got a very good price for our build due to the lack of demand at the time.
We signed our contract within a week of my sister & her husband signing their contract with the same builder. It was supposed to be a race but due to settlement issues, my sister was living in their new house before our slab had even been laid!
