Security

Urban development security is most effective when it's invisible: embedded in sightlines, access logic, landscaping, and spatial design. Core42 works with architects and urban designers to integrate protection into the design language, not against it.

The challenge

Where security meets the design process

Urban development security sits at the intersection of planning requirements, architectural ambition, commercial viability, and community safety. The challenge is delivering proportionate protection without compromising the qualities that make a development successful.

01 CPTED is a DA requirement in NSW and other states, but the quality of assessments varies widely. Many are produced as standalone compliance documents, filed with the submission and never referenced during design development.
02 Developers need proportionate security that doesn't compromise yield or amenity. Over-specified treatments reduce lettable area, restrict ground-floor activation, and create environments that feel institutional rather than welcoming.
03 Architects need security delivered in design language: spatial parameters, sightlines, access logic, and material considerations that integrate with their methodology. Risk registers and threat matrices don't translate into architectural drawings without interpretation.
04 Planners and consent authorities need defensible safety evidence grounded in site-specific crime data and spatial assessment. Generic CPTED checklists don't provide this; they need demonstrated design integration.
05 Mixed-use developments create interface complexity: residential entries adjacent to commercial lobbies, public through-site links crossing private forecourts, shared basement access. Each interface requires security treatment respecting different operational requirements and user expectations.

Our role

How we work on urban development projects

CPTED assessment for development applications

CPTED analysis grounded in site-specific crime data, spatial assessment, and the principles of natural surveillance, territorial definition, activity support, and access management. Structured to satisfy DA requirements while producing design parameters that architects can implement: sightlines, lighting, activation, and interface treatments translated into the language of the design brief.

CPTED & place-based safety

Threat and risk assessment proportionate to the asset

Evidence-based risk assessment that distinguishes credible threats from scenarios that don't warrant design responses. Proportionate analysis that considers the development's profile, location, use, and public interface, preventing worst-case assumptions from driving security treatments that compromise the design intent or commercial viability.

Security risk & threat analysis

Protective design that integrates with landscape and architecture

Bollards, barriers, and perimeter treatments specified as landscape and urban design elements, not security infrastructure imposed on the public realm. Performance specifications derived from the threat assessment, with materiality, form, and placement designed to integrate with the architectural language. Protection that works without announcing itself.

Protective design

Security design workshops with architects and planners

Collaborative design sessions where security requirements are developed alongside the architectural design, not delivered as a separate brief after the geometry is established. Early engagement that allows security considerations to influence spatial organisation, access logic, and interface design, when the cost of change is lowest and the design impact is greatest.

Questions

Frequently asked questions

How does CPTED integrate into the design process?

By translating crime prevention principles into spatial design parameters architects work with directly: glazing ratios for natural surveillance, level changes for territorial definition, programme placement for activity support, and landscape design for access management. The analysis should enter at concept stage when spatial organisation is still being determined, and be tracked through design development to ensure principles survive into construction documentation.

When should security be considered in urban development?

At concept design, before building geometry, access points, and ground-floor configuration are locked. At that stage, security inputs can influence spatial organisation, setbacks, vehicle approach paths, and interface design at minimal cost. For DAs requiring CPTED, early engagement means the assessment is informed by design intent rather than reviewing a resolved design after the fact.

What does a proportionate security assessment look like?

One that distinguishes credible threats warranting design responses from scenarios that don't justify protective expenditure. It uses evidence (crime statistics, site-specific analysis, and current threat intelligence) to establish risk positions rather than defaulting to worst-case assumptions. Assumptions are explicit, evidence is cited, and professional judgement is labelled. This protects developers from disproportionate expenditure while giving consent authorities defensible evidence that safety has been addressed.
