Hi, Just settled a sub-divisible property in Hornsby Council area where the minimum lot in R2 is 500 sqm (driveway cannot count towards the 500sqm). The land is around 20m width x 60m depth (see pictures. sorry, I can't draw in AutoCAD ). I am thinking of maximising the return so I would like to subdivide it in a way where I can fit a granny flat at front lot. I have drawn up a proposed subdivision and would like to get your opinions on 1. Who should I engage at this stage to start the subvdivision process? town planner? architect? any recommendation for Hornsby area? town planner with architect experience? an architect with town planner experience? 2. Who will give me suggestions or ideas on the best subdivision scenario? town planner? architect? or propertychat forum fellows? 3. In order to accommodate the granny flat, I can squeeze the back lot to 25m depth (currently 27m depth) if I need to. 4. Is 12m x 5m granny flat the best option in my scenario? not 10m x 6m or any other dimensions? 5. The council told me that the 3m setback can be sideways. It does not need to be 3m from the back lot's fence. Have you done this in the past? Thanks in advance.
