PS10 - get on the phone or meet an investor who has done a duplex. Its even better if you can get one that has done it in the area that you are looking to buy. There is a lot more to it than fees, costs, etc.

Those numbers are right. I did a survey on one of my properties at it cost $1,200. Architect fees are also correct however it is somewhat dependent on the type of design, site, council, etc.
