Pretty much was the case for me! The consultant I spoke to was helpful and forthcoming with information, and she asked me a lot of questions to ascertain what type of house I'd want, but she just never got back to me with any suitable houses! As I said, I know someone who is building with them and she has said they are very slow getting back to her, they drag their feet on a lot of issues, etc.
I bought my block in November 2007. I was in no hurry to build so I spent a considerable amount of time and looking at almost all the large builders and their designs. There are display homes I went to from that time onwards which are still being offered. I still have the brochures that I received from consultants in early 2008 with all their house plans and pricing lists, the majority of all those homes are still available to build now a year later. So I don't think they turnover that quickly.
