Plynth publishes guides and research about planning controls, source evidence and development activity.
Compare the Commission's zoned and commercially viable capacity estimates to see why a higher feasible share still does not predict how many homes will be delivered.
The August 2026 Sydney Plan targets are compared with its 2026 housing baseline and separate 2025 approvals, which do not measure target progress.
Compare projected population additions with aspirational additional-job targets across 33 councils in the August 2026 Sydney Plan.
The August 2026 Plan projects more small households alongside a 52% detached housing baseline. Local demand and feasibility still need testing.
The 2025 monitor shows where heavy-vehicle access lacks a published wastewater-access finding, alongside 2024 approval value.
Known preliminary estimates total 272,239 potential dwellings. See where the August 2026 planning-stage snapshot calls for closer coordination.
A 28 August 2026 Hurstville example shows how six mapped layers lead to questions about floor space, excavation and rail-corridor provisions.
The BCA is the building part of the NCC. NSW applies NCC 2022 Amendment 2 and will adopt NCC 2025 on 1 May 2027. How to check which edition covers your project.
Use the Court and NSW Caselaw search paths, identify the neutral citation, inspect the judgment and record what still needs legal analysis.
Choose NSW planning, hazard, infrastructure and context layers by the site question, then keep the parcel, source, date and limitation attached.
Six planning questions show how site, place, policy and programme analysis need different geographies, periods, measures and evidence limits.
Use a NSW DA map to inspect nearby lodgements and determinations without treating an application record as approval, construction or market supply.
Resolve the parcel and proposal, then check the LEP, SEPPs, maps, local DCP and approval pathway, with each control linked to its source.
LEPs and SEPPs are environmental planning instruments, a DCP adds design guidance and the NCC sets building requirements. How each applies to a NSW project.
Record zoning, building height and floor space ratio from NSW maps, then check each finding against the adopted map and applicable written provision.
An inspectable floor space ratio example showing the arithmetic, source checks and gross-floor-area assumptions that must be resolved for a NSW site.
Plynth's source-maintenance method for separating source identity, currency basis, checked date, change triggers and dependent-page review.
A provenance walkthrough showing how a planning question, parcel, instrument, provision, evidence and qualified conclusion remain connected.
