Hi Italianstylezz
I am in the process of doing a sub-division within the Banyule Council area in Melbourne. I have received development approval from the council and we start construction next Monday. My suggestions would be as follows;
1. Speak to a local council planning officer and discuss your rough plans for the proposed site.
2. If council has no major objections to you plans then get in touch with an architect or draftsperson and discuss you plans with them. They should be able to give you some advice as to how many units you might be able to build.
3. In order for the architect to draw up plans to submit to council the block will have to be surveyed by a surveyor.
4. Once the plans are drawn up you will need to get a town planner to draft a report stating how the proposed development meets the councils planning scheme.
5. You will also need an engineer to draw up a proposed storm water system.
6. Depending on the council you may need to submit a landscape plan for the development.
Our draftsman organised the town planner, engineer and landscape reports for us. I don't have the exact amounts but from memory the draftsman charged $2,000 for the plans for submitting to council, the tower planner cost us another $2,000 the landscape $500, the engineer $1,000 and the surveyor $1,500. Council application fees cost us about $600 so in total the initial application for development approval cost us about $7,600.
I would allow a year for the development approval to be granted, councils seem to be permanently understaffed. Once you receive development approval you then have to get the development built.
Our draftsman drew up our working drawings once we knew we would get development approval from the council, that cost us another $1,000 a structural engineer was also required to provide calculations for the working drawings which cost $1,000.
We then started talking to builders and got some quotes based on the working drawings.
One thing I would do differently if I was going through the process again would be to speak to a builder before the council signs off on the plans because draftsmen and a architects like to design houses but sometimes don't take into account the practicalities of actually building the house. Once the council approves the plans if you want to make any changes to the exterior of the house you have to resubmit the plans to council to get their approval, this can take quite a while. A builder will be able to suggest where you might be able to reduce building costs with different choices of materials.
As I said I'm no expert and there are probably people on the forum who have done many more sub-divisions than me but this has been my experience so far.
Good luck with it all, at first it seems very daunting but with a bit of guidance you'll get there.
