wellygary: The fact yours are cross leased tend to indicate they don't satisfy the councils minimum rules on individual sections, (or would require significant legal work to do so)Yeah that's where I was coming from.
When you subdivide your own property it's easier to bend the rules. Both parties need to agree to having closer boundaries etc, which is easy to agree on if you own the whole lot and actually are the 'both parties'. Negotiating with yourself is so much easier! So yeah, if they could do it easily then they probably would have, which means on such a small lot of land, you will probably find reasons why they didn't.
