Zoning, overlays, setbacks & envelope

The planning controls on a real lot.

Insitive Planning reads the zone, the overlays and the setbacks that apply to a surveyed Australian parcel, and shows the buildable envelope they leave — with the source and coverage stated on every line.

    Surveyed lot geometry
    The cadastral parcel as the state publishes it — boundaries, frontage, area.

    Zone
    The scheme zone the parcel sits in, and the use and density it permits.

    Overlays
    Every overlay that intersects the parcel — heritage, vegetation, flood, bushfire, character.

    Setbacks & height
    Front, side and rear setbacks and the height limit those controls impose.

    Buildable envelope
    What is left after the stack is applied to the measured geometry.

No sample lot is shown here on purpose. Controls are only ever reported against a real parcel you look up — where a control is not published for that council, the answer is “not available”, never an inferred figure.

Read the controls, or a summary of them.

Every layer resolves against the surveyed parcel, carries its publishing authority, and says so when a control is not published.

Zone on the surveyed parcel

The scheme zone resolved against state cadastral geometry, not a suburb-level approximation.

Every intersecting overlay

Heritage, vegetation, flood, bushfire, character and local overlays — each one named, not collapsed into a single risk word.

Setbacks from the scheme

Front, side and rear setbacks and height limits read from the applicable control, with the rule that produced each one.

Buildable envelope

The stepped three-dimensional envelope the stacked controls leave on the measured lot.

Orientation-aware

Frontage bearing measured from the boundary chain, so setback faces and solar aspect are the lot’s, not a rotation of it.

Sourced and dated

Each control carries its publishing authority and the vintage of the dataset it was read from.

Honest coverage

Where a council has not published a layer, the surface says so. A gap is reported as a gap, never filled with a plausible default.

Not a compliance opinion

These are the published controls and what they imply geometrically. They are not a planning-compliance assessment or an approval pathway.

New · Planning application preparation

Prepare an application on the real lot — with its shadows and its neighbours.

Set out a proposal’s storeys, wall heights and setbacks on the surveyed parcel. See its shadow at the 22 September reference times and the lot in 3D among what each neighbour is permitted to build. For a one-off report, or for planners to fast-track every application.

What this surface does not do

It reports controls. It does not certify compliance.

A zone, an overlay and a setback are facts a scheme publishes. Whether a particular proposal satisfies them is a judgement a planner makes — often with discretion the scheme grants them, and with reference to local policy that is not machine-readable.

So the surface stops where the evidence stops: it tells you which controls apply, where each one came from, and what envelope they leave. It does not tell you a proposal will be approved.

Every control line carries
  • Control
    The named zone, overlay or setback rule.
  • Authority
    The state or council body that publishes it.
  • Vintage
    When the dataset it was read from was published.
  • Coverage
    Present, or explicitly not published for this council.

Look up the controls on a lot.
