If you own a house on a standard suburban block, you have probably wondered whether your land is worth more than the price of one lonely lot. Very often it is — but only when it stops being one block and becomes part of a larger, better-shaped development site. When two, three or four adjoining owners choose to sell their blocks together, the combined parcel can clear the minimum-lot-size, frontage and density thresholds that a single block simply cannot reach on its own. That is the whole idea behind land assembly for owners: the sum is worth more than the parts, and the difference lands in the owners' pockets, not an agent's.
GoSiteHunt is an advertising and introduction platform built for exactly this moment. You check your address, we screen the indicative combined-site upside with your immediate neighbours, and you register your interest for free. When another owner in your run of the street registers too, we email both of you an introduction — and from there, whether you talk and what you decide is entirely between the owners. We never value your property, never negotiate, never relay offers and never touch a cent of the money. If you and your neighbours decide to test the market, you can list the combined opportunity on our off-market marketplace for a flat advertising fee — never a commission.
Everything below is indicative screening only. It is not a valuation, and not planning, financial or legal advice — always get your own professional advice before you act.
Why combined sites are worth more than separate blocks
Planning rules are the reason. Most residential zones set a minimum lot size, a minimum frontage and a maximum density before a site can be subdivided or redeveloped into townhouses or apartments. A single 600 m² block might fall just short of the numbers that unlock a multi-dwelling scheme — but line it up with the block next door and the combined ~1,200 m² site can comfortably clear the threshold. Suddenly the land supports more dwellings, and more dwellings means more end value, which is what a developer is actually buying.
There is also the shape of the deal. A wider, deeper, regularly-shaped parcel is cheaper and simpler to build on: fewer awkward setbacks, one driveway instead of three, better solar orientation, and room for a design that a planner will actually approve. Developers pay a premium for that certainty. So when you sell adjoining blocks together, you are not just selling more square metres — you are selling a site that carries less planning risk and more upside. That is the combined site value that GoSiteHunt screens for, and it is routinely higher, per block, than what each owner would get selling alone to an owner-occupier.
None of this is guaranteed. Yields depend on the zone, the market, the specific parcels and a proper planning assessment — which is exactly why our figures are indicative screening, not a valuation. But the underlying logic is well understood in the industry, and it is the reason "amalgamation" and "land assembly" plays exist at all.
How the neighbour introduction actually works
This is the part people most want to understand, so here it is plainly. GoSiteHunt does not cold-call your neighbours, does not put a sign on your lawn and does not tell anyone anything the moment you register. Registering is silent. Your details are never shown publicly and are never handed to developers or agents.
What we do is match registered owners to other registered owners. When you register, we note your address. When another owner within your run of the street also registers — and only then — we send both of you an email introduction. That email is the entire service on the buyer-matching side: it says a nearby owner has also registered interest in selling together, and it lets you decide, in your own time, whether to have a conversation. There is no obligation, no listing created automatically, and no third party in the room. The consent box on the form is what makes this legal and clear: you are agreeing to be introduced to nearby registered owners, and to have them introduced to you.
Because we introduce owners to owners, the value stays with the owners. We are not standing between you and a buyer taking a slice — we are simply the noticeboard that lets neighbours who would never otherwise talk discover they share an opportunity.
The flat-fee marketplace — never a commission
Once you and your neighbours have decided you want to test the market together, you can list the combined opportunity on GoSiteHunt's off-market marketplace. Here is the important difference from a traditional agency: you pay a flat advertising fee to have the opportunity listed, and that is it. There is no percentage commission on the sale price, no success fee scaled to the value of your land, and no incentive for us to push you toward a deal you do not want.
That structure is deliberate. A commission model quietly punishes owners of higher-value combined sites — the more your land is worth, the more it costs you. A flat fee does not. It also keeps our role honest: GoSiteHunt is an advertising platform, not an agent. We never value your property, never negotiate on your behalf, never relay or filter offers, and never handle the money. When a developer is interested, they come to you and your co-owners directly, and you run the sale on your terms — with your own conveyancer, lawyer and advisers, exactly as you would any property sale.
Developers use the same platform from the other side. The Amalgamations tool lets buyers screen the cadastre around a target address and find groups of adjoining lots that, combined, support a bigger scheme than each does alone. So a genuinely motivated buyer audience is already looking for precisely the kind of combined site you and your neighbours can offer.
What happens after you register
Registering takes about a minute and commits you to nothing. Here is the honest sequence of events:

Planning and owner-agreement realities to keep in mind
Selling together is powerful, but it is not automatic, and it is fair that you know the catches up front. First, every owner in the group has to agree. One holdout can stall an assembly, so the earlier neighbours start talking, the smoother it goes — which is precisely why an early, no-obligation introduction is useful. Second, planning still applies. A combined site's dwelling yield depends on the zone, overlays, heritage, easements, trees, slope and a proper planning assessment; our screening uses zone-typical numbers, not an approved design.
Third, due diligence does not disappear. Titles, contracts, settlement timing and how the sale proceeds are split between owners are all things for your own conveyancer and lawyer to handle. GoSiteHunt does not draft agreements, does not advise on how to divide proceeds and does not resolve disputes between owners — we introduce, and you and your professionals do the rest. Tools like our subdivision calculator and feasibility software can help you and a buyer sanity-check what the combined site might actually yield, and the development site finder shows how buyers hunt for sites like yours — but none of these replace professional advice tailored to your property.
Indicative screening only — not a valuation, and not planning, financial or legal advice.
We'll email you if an owner near you registers too. Nothing else happens without you.
Frequently asked questions
Can I really sell my block together with my neighbours?
Yes — and it is one of the strongest plays available to a suburban owner. When adjoining owners sell their blocks together, the combined site can support more dwellings than each block does alone, which lifts the value per block. GoSiteHunt helps by screening the indicative combined-site upside and introducing you to nearby owners who have also registered. The decision to sell, and every negotiation, stays entirely with you and your co-owners.
What is "combined site value" and why is it higher?
Combined site value is what a larger, better-shaped development site is worth once neighbouring blocks are merged. It is usually higher per block than selling alone because the combined parcel clears minimum-lot-size, frontage and density thresholds, carries less planning risk and is cheaper to build on — all things developers pay a premium for. Our figure is indicative screening based on zone-typical yields, not a valuation.
Does GoSiteHunt value my property or negotiate for me?
No. GoSiteHunt is an advertising and introduction platform, not an agent. We never value your property, never negotiate, never relay or filter offers and never handle money. We screen the combined-site upside, introduce registered owners to each other, and — if you choose — advertise the combined opportunity on our marketplace. Everything after that is between you, your co-owners and your own professional advisers.
What does it cost, and do you take a commission?
Checking your address, registering your interest and receiving neighbour introductions are all free. If you and your neighbours decide to list the combined opportunity on our off-market marketplace, you pay a flat advertising fee — never a commission. We take no percentage of your sale price, so a higher-value site never costs you more to advertise.
Will my neighbours find out I registered?
Only if they register too. Registering is silent — no neighbour, developer or agent is told anything when you sign up. We only introduce you to another owner near you once that owner has also registered interest, and only because you ticked the consent box. Your details are never shown publicly.
What if my neighbours do not want to sell?
Then nothing happens, and you have lost nothing by registering. A land assembly needs every owner in the group to agree, so a reluctant neighbour can pause things. Registering early simply means that if a neighbour ever does become interested, you are the first to know — with no obligation on either side.
Is this the same tool developers use?
It is the owner-facing side of the same engine. Developers use the Amalgamations tool to screen the cadastre and find groups of adjoining lots that combine into a bigger scheme. This page gives owners the mirror image: a way to raise your hand, meet nearby owners, and reach that developer audience directly. See our full FAQ for more.
