Site appraisal

Draw a line. Get the whole picture back.

Area and perimeter, the authority, every constraint that touches the line, the factors that move the decision either way, that council's own approval rate, and the applications already lodged within 500 metres.

The Wren site appraisal panel listing the constraints found against a drawn boundary, with a traffic-light state for each.
The appraisal panel, as it returns. Constraints resolved against the boundary, each one traceable to the body that publishes it.

What comes back

Every layer a planning officer will look at.

The appraisal does not summarise the constraints. It resolves each one against the geometry you drew, states whether it touches the line or merely sits nearby, and names the dataset it came from with the date that dataset was last refreshed.

Where a constraint is genuinely bad it says so. A tool that only ever returns good news is a tool nobody can plan around.

Every source, named

The sequence

Four steps, and three of them are ours.

  1. 01

    You draw the boundary

    A polygon on the map. Snap it to a title boundary or draw it freehand.

  2. 02

    We resolve the constraints

    All 88 live layers tested against your geometry, not against your postcode.

  3. 03

    We name the route

    Householder, minor, major, prior approval or certificate, and why that one.

  4. 04

    We price the set

    The documents that route requires, and the council fee that goes with it.

Judgement, not just data

What actually moves a decision.

The constraints are facts. The likelihood is a judgement, and it is shown with the factors that produced it rather than as a bare score, because a number you cannot interrogate is worse than no number at all.

How we compute our own rate

Constraints
What touches the line
Designations, flood risk, protected trees, heritage assets and article 4 directions, each traced to its publisher.
Precedent
What this council has already decided
Applications determined within 500 metres, with their outcome and how long each one took.
Policy
What they will decide against
The adopted local plan policies engaged by your scheme, with the passage that applies.
Requirements
What they will insist on
Your authority's own published validation list, not a national template.

The fastest way to understand a site is to draw on it.

Put a line around any site in the country and watch what comes back. It takes about fifteen seconds and costs nothing.
