Of course! Dwelling size not lot size! Idiot. Thanks Westminster, I've been reading way too much Res Code!:roll eyes:
I've been doing a bit more thinking, and it is a bit of a weird shaped block, so I may be able to go for the 5% less area on the back two plots and subdivide as I've sketched out in the attached plan. At 875m2 it is so close to being 3!
In its current format, there is a 3.5m wide driveway for the back, which has a small one bed lot, and a minimum size lot. If the front block is 460m2 I could get a granny flat on there as well (possibly). The front would have its own driveway. I could take a few more metres off and add to the others...
Obviously I haven't started thinking about setbacks or open space reqs or anything so it may not work at all, but as a subdivision of lots under the laws does it work? I guess I'm subdividing a battle-axe shape - I don't even know if this is possible, or if it would be easier just to cut the site in half and build something else on the back, like a 3x2 or similar.
Or do as westminster suggested and put 2 x 1 beds down the back
Again, the advice/ideas are very much appreciated!
It will still have to meet the average lot size requirements. Ie 300m2 x3 so 900m2 lot. But not sure if 5% variation can apply to average or only to the minimum lot sizes.
Cheers
