Hi Paperchaser I am new to this forum and I know this thread is a few months old, but thought I would add my two cents in in case you are still looking for costing. We have just embarked on getting a DA for 3 villas in Sydney, slightly tricky sloping site with special drainage/ flooding requirements and we are paying similar to Marisa above, 20k (for DA only does not include CC). We are using an architectural designer, he seems a bit cheaper than an architect and for an investment property we are happy to not have all the bells and whistles. Having said that I am an Interior designer experienced in high density residential design so I have driven the space planing, materials and elevation designs…..I really just need my guy to do the drafting and “boring/dirty” work for me :-). A friend has just paid a qualified architect to design three dwellings and I believe his architect charged him a total of 16k including CC documentation.

Have you got any prices yet?
