CLAUSE 54 / 55 / 57 PATHWAY

Where applicable, the relevant Victorian residential planning provisions are identified from the current planning framework and project information.

Local Planning Scheme Controls

Council-specific overshadowing controls · neighbourhood character overlays · design and development overlays · confirmed before work starts

Shadow Footprints at All Required Times

Existing and proposed shadows distinguished by colour at every council-required time-point — 9am, 12pm, 3pm AEST at 22 September (Equinox) as standard, with additional times where the planning scheme requires them.

Overshadowing Requirement Review

Explicit confirmation of whether the proposed development meets the applicable overshadowing requirements under the current Victorian planning provisions — stated clearly in the methodology note so your planner can reference it directly in the DA assessment.

Full Methodology Statement

Written methodology confirming software and sun-path model, site coordinates, applicable planning reference and standard, analysis dates and times, and true north basis. Ready to include in your DA documentation as-is.

True North & Survey-Accurate Geometry

True north confirmed against your registered survey plan. Site boundaries, neighbouring property footprints and street alignment verified before work starts. Scale bar and north point annotation consistent with your architectural drawings.

Print-Ready PDF + DWG / ArchiCAD Source

A4/A3 print-ready PDF formatted for DA lodgement, plus full DWG and ArchiCAD source files. No locked files, no watermarks. Your architect can incorporate the drawings directly into the DA documentation set.

One revision round is included within the agreed project scope. We review the request, update the analysis and re-issue the set within 48 hours.

Current Victorian Provisions

Overshadowing of Private Open Space

The applicable clause and any local schedule requirements are confirmed for the specific development type before modelling begins. Both existing and proposed shadow conditions are modelled and the comparison clearly documented.

If an existing dwelling already receives less than 5 hours, the proposed development must not further reduce it below that level.

Pre-reform reference: B21

Current Victorian Provisions

Solar Access to Existing Dwellings

The applicable clause and any local schedule requirements are confirmed for the specific development type before modelling begins, addressing solar access to habitable room windows of adjoining properties. The objective is to ensure that proposed development does not significantly reduce the solar access currently enjoyed by neighbouring habitable rooms.

Local planning overlays may impose additional controls beyond the base provisions. We confirm the applicable standard before commencing.

Victoria's residential planning provisions were reformed in 2025. Depending on the scale of development, Clause 54, Clause 55 or Clause 57 of the planning scheme now applies, and overshadowing of neighbouring secluded private open space remains a core assessment requirement. The pre-reform standards commonly cited as A14 and B21 have been restructured under the current provisions. We confirm the applicable clause, standard and any local schedule requirements for each project before work starts. Individual councils may impose additional requirements.

Shadow diagrams for Melbourne DA submissions are assessed at 22 September (Equinox), at 9am, 12pm, 3pm AEST. We review the requirements against the relevant planning scheme provisions, local schedule and project requirements.

We need your DA drawings (DWG, PDF or ArchiCAD preferred), a registered survey for true north and boundary verification, and your council name or DA reference. IFC and Revit files are also accepted.
