Hi
From past experience I found it better to talk to the council before engaging a draftsman,see what they will or won't allow you to build.Then proceed and get your plans drawn up.If you go straight to adraftsman and tell them to draw up what you want sure they'll do it but if council don't agree with the plans or you get any objections you will have to change plans at acost or go to VCAT at a cost.
Good luck
