Fire safety is one of the most critical, yet often underestimated, aspects of home design and construction. Whether you’re building a new home or renovating an existing one, the decisions you make early on can dramatically affect how a fire starts, spreads, and is controlled.
VIKON see fire safety not as a checklist item, but as an integrated part of good design. A well-designed home should protect its occupants, limit damage, and meet New Zealand Building Code requirements without compromising comfort or aesthetics. Understanding how modern fire protection works allows you to make informed decisions that suit your layout, budget, and lifestyle.
Fire Prevention and Containment: The Two-Layer Approach.
Active Fire and Passive Protection Systems
Active systems respond when a fire starts. They require a trigger to activate and provide immediate warning or suppression. These systems include smoke alarms, heat detectors, and sprinkler systems. Passive fire protection works quietly in the background. It does not require activation and instead focuses on slowing fire and smoke spread through the structure of the building. This includes fire-rated walls, ceilings, doors, linings, and protective coatings.
Smoke Alarms and Fire Detectors: Your First Line of Defence
Smoke alarms are the most fundamental fire safety device in any home. They provide early warning, allowing occupants to evacuate before conditions become life-threatening. According to Fire and Emergency New Zealand (FENZ), 40% of residential fires they attend occur in homes without working smoke alarms.
Modern smoke alarms typically use one of two detection methods: ionisation or photoelectric. Ionisation alarms are more sensitive to fast-flaming fires, while photoelectric alarms are better at detecting slow, smouldering fires. FENZ strongly recommends the latter as it more effective in real-world residential fire scenarios.
Placement and Maintenance
Smoke alarms should be installed in every bedroom, hallway, and living area. Kitchens, bathrooms, laundries, and garages are better suited to heat alarms rather than smoke alarms to avoid false activations.
Regular maintenance is essential:
Monthly testing ensures the alarm functions correctly.
Cleaning every six months prevents dust-related false alarms.
Alarms should be replaced entirely every 10 years, even if they appear to be working.
For households with hearing-impaired occupants, specialised alarm systems with strobe lights, vibrating pads, or lower-frequency sounds can be integrated into the overall fire safety plan.
Fire Extinguishers: When and How to Use Them Safely
Fire extinguishers can be effective for very small, contained fires, but only when used correctly and safely. They should never replace evacuation as the priority.
An extinguisher should only be used if:
The fire is small and contained
Everyone has already evacuated
Fire and Emergency New Zealand has been called
You have a clear escape route
In residential settings, kitchens are the most common fire risk area. A wet chemical extinguisher is best for cooking oil and fat fires, while an ABE dry powder extinguisher can handle a wider range of fires elsewhere in the home. Both should be mounted visibly and safely, out of reach of children.
Fire Blankets: Simple, Effective, and Underused
Fire blankets are an excellent tool for smothering small fires, particularly cooking-related fires and clothing fires. They work by cutting off the fire’s oxygen supply and are simple to use, making them ideal for kitchen environments.
Fire-Resistant Materials
Material selection plays a major role in fire safety and containment. Many modern building products are designed to resist ignition, slow fire spread, or maintain structural integrity during a fire.
Fire-resistant plasterboard and wall linings are commonly used in garages, stairwells, and shared walls. Cabinetry and joinery materials can also influence fire behaviour. Certain coatings and substrates offer improved fire resistance, while intumescent paints expand under heat to form a protective barrier. Even the choice of insulation, flooring, and surface finishes can affect how a fire develops.
Sprinkler Systems
Residential sprinkler systems are one of the most effective fire protection measures available. They operate automatically, activating only in the area affected by heat, and can significantly reduce fire spread and damage.
Sprinkler systems are best installed during new builds or major renovations, though retrofitting is becoming increasingly feasible. Installation typically uses standard domestic plumbing and can be completed quickly. On average, sprinklers add approximately 2% to the total build cost.
Fire Safety and the New Zealand Building Code
If your project requires building consent, the New Zealand Building Code sets clear fire safety requirements. These include the installation of interconnected smoke alarms in all bedrooms, hallways, and living spaces.
Depending on the size, height, and layout of the home, additional fire safety measures may be required, such as fire separations, protected escape routes, or enhanced passive protection.
Designing for Safety Without Compromise
Fire safety should never feel like an afterthought or an obstacle to good design. When planned early and integrated properly, safety measures enhance a home’s resilience without detracting from comfort or appearance.
At VIKON, we help homeowners understand what is required, what is recommended, and what makes sense for their specific situation. Whether you’re building new or renovating, our role is to guide you through these decisions clearly and responsibly, so your home is not only beautiful, but safe, compliant, and future-ready.
A dream home should give you peace of mind, not uncertainty. Fire safety is a crucial part of achieving that confidence.
