The problem
"What can I build here?" still takes days to answer.
Controls are scattered across LEPs, DCPs, SEPPs and the NCC. Overlays change the answer lot by lot. The expertise isn't the bottleneck — the searching is.
Plynth compresses that diligence into minutes,
without losing the rigour.
The proof
Ask. And watch the receipt assemble.

>Can I build an 8.4 m dwelling at 12 Harbour St, and what applies to the lot?
AnswerCompliant · conditional
The maximum building height for this lot is 9 metres under the LEP height-of-buildings map. The proposed 8.4 m sits within it.
Floor space ratio is capped at 0.5:1. The heritage conservation overlay applies, so a Heritage Impact Statement is required.
Source● confidence 0.97
§ 4.3 Height of buildings(1) The objectives of this clause are to establish building heights ... the maximum height of a building must not exceed 9 metres as shown on the Height of Buildings Map.

Product features
the working surfaceThe law is a field. The land is its source.
field study · law follows landPlanning controls aren't documents to Plynth — they're a field around the land. Zoning, height, heritage, hazard: each radiates from the parcel and is measurable at it. Resolve the lot, and the field becomes legible.

How Plynth is different
3 principles01
We resolve the site before we read the law.
Planning controls follow the land. Plynth resolves the site's spatial context: zone, overlays, heritage, flood and bushfire, so the answer is grounded in the controls that actually apply to this lot.
02
We separate what's measurable from what's a judgement call.
Deterministic checks return pass, fail or undetermined. Discretionary matters are surfaced as findings that require assessment: flagged for your professional judgement, never quietly decided for you.
03
Compliance status is assigned by code, not by a language model.
The final status is computed by a deterministic decision matrix. The model's job is to explain the result in plain English, not to decide it. That boundary makes the output auditable.
Trust is the product
You're never asked to trust the machine.
