The Small-Lot Subdivision Where You Build Before You Can Sell

SOME NEW LOTS NEED HOMES BEFORE TITLES.NSW: test integrated-housing conditions and the construction sequence.

You find a wider-than-average block, do the arithmetic, and realise you can fit three narrow dwellings instead of two standard lots. The yield jumps. Then you read the council's small-lot controls and discover that on lots under 300 square metres, the subdivision plan will not be released until the dwellings are out of the ground to frame stage.

That single condition changes which deal you are actually doing. It is no longer a land subdivision. It is a construction project with a subdivision at the end of it.

The deal question: how long is my money in before I can sell anything?

On a conventional subdivision you create the lots and sell them, and construction is somebody else's problem. On small-lot integrated housing the order is reversed. You buy, you design, you obtain consent for subdivision with dwellings, you build to at least frame stage, and only then can the plan of subdivision be released and separate titles created.

So the real question is not whether the yield works. It is whether your finance, your holding cost and your cash flow can survive that sequence.

The checks a student would run, in order

1. Establish which approval pathway applies. Camden Council's DCP 2019 Part 3 treats integrated development as the subdivision and construction of dwellings on small lots of less than 300 square metres, and splits it into Pathway 1 for detached or abutting dwellings and Pathway 2 for attached or semi-detached dwellings. The pathway determines the conditions you get, so read it before you commit to a product type.
2. Read the release-of-plan timing rule. Under Camden's pathway table, release of the subdivision plan is not to occur earlier than post a satisfactory frame inspection from a principal certifying authority, for both pathways. That is your funding horizon. Write it into your cash flow before you write it into your offer.
3. Understand the section 88B restriction. Under Pathway 1, where detached or abutting dwellings are proposed, a section 88B restriction is required so that only the approved dwellings shown on the instrument should be built. Under Pathway 2 the restriction is not required because the dwellings must be constructed as integrated housing. Either way, the instrument ties future owners to a design, and it is a title document that has to be drafted properly.
4. Check whether you need a zero lot line. Narrow lots often only work if a dwelling sits on the boundary. Camden permits zero lot line development only on lots less than 400 square metres, and requires an easement on the adjoining burdened lot: 900 millimetres for single storey zero lot walls and 1200 millimetres for two storey zero lot walls, to enable servicing, construction and maintenance of the adjoining dwelling.
5. Register the easement before the subdivision certificate. Wollondilly Shire Council's DCP 2016 Volume 3 requires that where a zero lot line boundary is created, satisfactory easements be provided on the adjoining lot for eave overhang, drainage, maintenance and any other relevant matter, and that they be registered as a restriction on the title of the burdened lot prior to the issue of any subdivision certificate.
6. Have the instrument drafted, not copied. Both councils place specific wording requirements on the instrument. Camden requires the section 88B instrument for the benefited and burdened lot to include a note identifying the potential for a building to have a zero lot line, and to be worded so that the council is removed from any dispute resolution process between adjoining allotments.
7. Confirm the instrument still meets the current lodgment rules. A section 88B instrument is a statutory document under the Conveyancing Act 1919, not a private agreement. NSW Land Registry Services' Registrar General's Guidelines confirm it may be used to create easements, profits a prendre, restrictions on the use of land and positive covenants benefiting or burdening land, and that the requirements are set out in schedule 9 of the Lodgment Rules, with the instrument now to be prepared using the Digital Form Builder in LRS Connect unless an exception applies. A clause copied from an older dealing may no longer be in the right form. Have your solicitor prepare it, and check the lodgment rules current at the date you lodge.

The trap: pricing it as a land subdivision

The trap is doing a two-lot subdivision feasibility and then choosing a three-lot small dwelling product, without re-running the finance model. The construction cost, the construction program and the holding cost all land in the same period, with no title release and no settlement income until frame stage.

There is a second trap in the design itself. Narrow attached dwellings mean party walls, zero lot lines, easements and building envelopes that are set by the subdivision consent. If the envelope the council approves does not comfortably accommodate the product your designer intended, you discover the problem after consent, when changing it means a modification application.

What the result means for feasibility and the offer

This structure changes three numbers at once. Peak debt rises because construction and land are funded together. The holding period lengthens because the release of the plan does not happen on approval. And the margin is delivered later, which matters if your finance has a maturity date.

The right response is to model the build-then-release sequence explicitly and test whether the additional margin on three small dwellings genuinely beats the simpler margin on two conventional lots. Sometimes it does, comfortably. Often the honest answer is that the extra yield is doing less work than the extra risk and time.

Where the structure does stack up, it belongs in the offer. Your acquisition price should reflect that you are funding a construction project, not buying land with a yield uplift.

The Think Property Club lesson

Students are taught to ask what a consent condition does to the order of events, not just to the list of approvals. Two projects with the same yield can be completely different businesses depending on when titles are released and when money comes back.

That is the discipline: read the pathway, read the timing rule, read the title instrument requirements, then rebuild the cash flow around what you have read. The council is telling you the sequence. Your job is to price it.

Practical next steps checklist

• Confirm whether your product falls under an integrated development pathway and which one.
• Find the release-of-plan timing condition and write it into the cash flow as a fixed constraint.
• Establish whether a section 88B restriction is required and what it will bind on title.
• If zero lot lines are needed, confirm the permitted lot size and the required easement width.
• Check the easement must be registered before the subdivision certificate issues.
• Engage a solicitor to draft the instrument with the required notices and dispute-resolution wording.
• Re-run the feasibility as a build-then-release project, not a land subdivision.
• Compare the extra margin on the small-lot yield against the extra time, risk and peak debt before choosing.
