A CPTED report helps a development get through approval. A CPTED design review checks that what the report recommended is still in the drawings when the building is built.
The two are not the same job, and the gap between them is where most CPTED outcomes are lost. A recommendation made at DA stage can be diluted, deleted or reinterpreted by the time the construction documents are issued, and nobody notices because nobody is checking.
This page explains what a CPTED design review involves, when it adds the most value, and who commissions one in Perth and across WA.
What a CPTED Design Review Is
A CPTED design review is an independent check of design documentation against the CPTED recommendations and conditions that apply to a project. The reviewer reads the drawings at defined stages and confirms whether each recommendation has been carried through, partly addressed or missed.
It is also useful earlier, as a design-stage review, when the aim is to find crime risks in a layout before the design is locked in, rather than test a finished design against a report.
A CPTED report tells the project team what should happen. A design review tells everyone whether it did.
Why CPTED Recommendations Get Lost
Most CPTED recommendations don’t fail because anyone objects to them. They fail because the project moves on. Common causes include:
- Value engineering. Landscaping, lighting and entry treatments are easy targets when budgets tighten.
- Change by other consultants. A landscape architect adjusts planting, a lighting designer changes the layout, or a services engineer relocates a plant room, each with good reasons but without CPTED input.
- Interpretation at tender. A recommendation written in general terms is priced and built in whatever way the contractor reads it.
- Time. The consultant who wrote the CPTED report often finishes at approval, while the design keeps changing for months afterwards.
By the time anyone notices, the fix is a retrofit, which costs far more than getting it right on paper.
When a Review Adds the Most Value
A review can be placed at any stage, but these are the points where it usually matters most.
Concept and schematic design. The cheapest time to change a layout. Sightlines, building orientation, entry locations, ground-floor frontages and the position of carparks and service areas can still move without cost.
DA lodgement. A check that the lodged drawings are consistent with the CPTED report, so the assessing authority sees a coherent package.
Detailed design. Landscape, lighting and wayfinding are usually resolved here, and this is where intent most often drifts.
Construction documentation and tender. A final check that CPTED measures are specified clearly enough to be built as intended, and that nothing has been lost in the issue set.
Pre-completion. A site inspection to confirm what was built matches what was documented, particularly for lighting, planting heights and access arrangements.
Not every project needs every stage. For a smaller development, a single review at construction documentation stage is often enough.
What a CPTED Design Review Looks At
The review follows the CPTED principles, applied to the drawings in front of the reviewer rather than to a generic checklist.
Natural surveillance and sightlines. Whether people can see and be seen along key routes, entries, carparks and shared spaces, and whether columns, walls, fencing or planting create blind spots.
Access and movement. Entry points, pedestrian and vehicle routes, wayfinding and how the layout channels people through observable, well-defined paths.
Territorial definition. Whether the boundary between public, semi-private and private space is clear and appropriately signalled.
Activation. Ground-floor frontages, active uses facing public space and how the building supports legitimate activity at different times of day.
Landscaping. Planting heights and species against sightlines, and whether mature growth will create concealment.
Lighting. Layout and coverage against the CPTED intent, with performance checked against AS/NZS 1158 where relevant. Lighting is often detailed by others, so it is a common place for drift.
Carparks, basements and service areas. Concealment points, recesses, stairwell and lift approaches and after-hours conditions.
Maintenance and management. Whether the design can realistically be maintained, because a well-designed space that is allowed to decline sends the wrong signals.
What You Receive
The output is built to be used by the project team, not filed.
A review register lists each CPTED recommendation or planning condition, where it sits in the drawings, whether it has been addressed, partly addressed or not addressed, and a short comment on what is needed.
Where relevant, marked-up comments on the drawings point to specific locations, so designers know exactly what to adjust.
A close-out summary records the final position. Where a planning condition requires evidence that CPTED measures have been incorporated, this gives the project team something clear to submit.
Who Commissions a CPTED Design Review
Architects and design teams who want an independent check that the CPTED requirements on their project are carried through.
Developers and project managers managing a planning condition and wanting confidence it will be cleared without surprises late in the process.
Builders and contractors delivering a project where CPTED outcomes were set at approval and need to be specified and built correctly.
Local governments and assessing officers who want independent review of CPTED material submitted with an application. Smartsec is a WALGA Preferred Supplier, so councils can engage us without a separate procurement process.
Government and infrastructure project teams running staged design reviews across a large project.
Why Independence Matters
A CPTED review done by the party selling the security system, the landscaping or the lighting has an obvious conflict. An independent reviewer has nothing to supply and nothing to defend, so the review reflects what the drawings show.
Independence also supports the governance side. A reviewer who is separate from the design team can give a clear position to a council, a project board or an assessing authority.
Standards and Frameworks
Smartsec’s CPTED work is aligned with ISO 22341:2021 (Security and resilience – Protective security – Guidelines for crime prevention through environmental design) and the WA Government’s Safer Places by Design guidelines published by the Department of Planning, Lands and Heritage. Those guidelines set out a six-step CPTED process that runs through design development and into delivery and evaluation, not just approval, which is the same logic a design review applies.
Lighting is considered against AS/NZS 1158 where relevant, and findings are rated using ISO 31000:2018 risk methodology so priorities are clear. Our approach to place-based safety and how CPTED and physical security controls work together are covered in more detail elsewhere on this site.
