01
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.

>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.

The problemWeeks of consultant work → minutes of cited analysis
"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. Consultant reports take weeks and still arrive without sources. Plynth compresses that diligence into minutes without losing the rigour.

How Plynth is different
3 principles02
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.
