The mechanism

Four checks, before anyone reaches you

Every one of them is something you could do yourself. What we sell is that it has been done, dated and published — and repeated on a schedule, because a check that happened once is worth nothing.

  • 01 · Licence

    Looked up on NSW Fair Trading's own public register — number, class and status, with the date we looked recorded.

  • 02 · Insurance

    Public liability plus whatever warranty or indemnity cover NSW requires. Sighted by us, not self-declared on a form.

  • 03 · Still trading

    Solvency re-checked on a schedule. A licence stays current right up until the day a company fails.

  • 04 · Works in Riverstone

    Confirmed with the builder against the suburbs they genuinely service — not a radius drawn on a map.

How Riverstone compares in North West Sydney

Overlay families mapped in each suburb we have read in this region. More mapped controls generally means more assessment before you can price a build.

What building in Riverstone actually involves

Riverstone maps a dominant maximum building height of 28 m and a dominant floor space ratio of 2.2:1. Those two numbers together describe apartment-scale development as the normal outcome here rather than the exception, and that is unusual enough to be the first thing to understand.

Dominant is the word doing the work

In most suburbs the tall controls sit on a handful of parcels near a station and the rest of the land is low. Here 28 m is the most common control, on 12 of 32 mapped parcels, and 2.2:1 is the most common floor space ratio, on 12 of 29. When a control is dominant you can reason from it: the reasonable expectation on mapped land in Riverstone is substantial density, not a detached house on a block. Controls as low as 11 m are also mapped, so the address still decides — but the direction of travel is clear and it is published.

What that means if you are buying a house here

Mostly it is about what happens beside you rather than what you may build. A 2.2:1 floor space ratio on an 800 m² parcel permits roughly 1,760 m² of floor area — which is not a neighbouring house, it is a building. If outlook, light or quiet is part of why you are buying, the height and floor space controls on the adjoining parcels are the searches that matter, and they take minutes.

Twenty-seven parcels reserved for infrastructure

This is the highest infrastructure reservation count we have published. Parts of Riverstone are reserved for future public acquisition — 27 parcels for infrastructure, eight for public recreation, one for a local road and one for local open space. A reservation earmarks land to be acquired by a public authority; it constrains what will be approved and affects what the land is worth, and no design resolves it. At 27 parcels this is not a remote possibility in this suburb, and the check against an address is a matter of minutes.

Three zones, including R4

Residential zoning spans low, medium and high density — mapped. R4 is the land that pairs with the 28 m controls. For an owner on R2 land the useful check is the zone on the land behind and beside — the difference between an R2 neighbour and an R4 neighbour is the difference between the street now and the street in a decade.

Thirty-seven heritage features

A moderate count. Where a listing reaches a property, consent covers both demolition and new work, measured against the significance recorded for it. Conservation areas reach land carrying no listing of its own, so run that search separately from the item search.

No acid sulfate soils, and the ground that does matter

With none mapped, digging here is a geotechnical matter rather than a soil management one. On the Cumberland Plain the substantive issue is reactive clay: the site classification a soil test returns for your specific lot decides the footing system, two lots in one street can come back differently, and a slab price given before that test is an estimate rather than a price.

What to establish first in Riverstone

The height and floor space controls on the adjoining parcels, not just your own — because both are dominant and both are substantial. Then the reservation check, given 27 infrastructure parcels. Then the zone, the heritage position, and the site classification.

What to ask a builder about a block in Riverstone

Each one is here because of something mapped in Riverstone. Take them to whoever quotes.

  1. 01

    Which of the 3 residential zones mapped in Riverstone covers this address, and what does that one permit that the others do not?

  2. 02

    Have you had an application through Blacktown City Council where a heritage control applied, and how long did the assessment take?

  3. 03

    What height control is mapped at this address? It is set block by block in Riverstone, not suburb-wide.

  4. 04

    What floor space ratio applies at the address, and what floor area does that actually allow on this block?

Questions about building in Riverstone

What does a dominant 28 m height control mean?

That substantial density is the normal outcome here rather than the exception. 28 m is the most common control, on 12 of 32 mapped parcels, alongside a dominant 2.2:1 floor space ratio. Controls as low as 11 m also exist, so the address still decides.

How much building does 2.2:1 permit?

On an 800 m² parcel, roughly 1,760 m² of floor area — which is not a neighbouring house, it is a building. If outlook, light or quiet matters, check the height and floor space controls on the adjoining parcels.

How much land is reserved for acquisition?

Twenty-seven parcels for infrastructure — the highest count we have published — plus eight for public recreation, one for a local road and one for local open space. A reservation constrains what will be approved and affects value, and no design resolves it.

What zones apply?

R2 Low Density, R3 Medium Density and R4 High Density Residential. R4 is the land pairing with the 28 m controls. For an owner on R2 land, the zone behind and beside is the check worth running.

What footing system should I expect?

That follows the site classification a soil test returns for your specific lot. On the Cumberland Plain reactive clay is the substantive issue, two lots in one street can come back differently, and a slab price given before the test is an estimate rather than a price.

How this works

  1. 01
    Tell us about the build

    Six questions, about three minutes.

  2. 02
    We match it against Riverstone

    Against the 3 residential zones mapped here, 3 overlay families, 37 heritage records — and against which builders hold the right licence class for it, have done it before, and actually work under Blacktown City Council.

  3. 03
    One recommendation, with the reasoning

    Not six quotes to sift. We negotiate on your behalf; you deal with the builder directly. Builders pay us, only once you sign.

No catch

What you are agreeing to

  • Nothing. There is no contract with us, no account to create, no card, and nothing to cancel.
  • No obligation to use whoever we recommend. Take the name and the reasoning and do what you like with it, including nothing.
  • No phone number needed to start. Give us one if you want to be called; otherwise we write.
  • One builder contacts you, not six. And only after you have seen the brief and said yes.
  • Your details go to that builder and nobody else. Never sold, never auctioned, never shared with a panel.
  • If we have nobody in Riverstone, we say so. That is a real answer we give, and the empty builder list above is the proof we mean it.
