Summary
Portal frame saves time because the structure removes work from the rest of the build. Less bracing, faster enclosure, and cleaner service runs all add up. The numbers above show where that time can come back into your programme.
Based on placeholder modelling for a typical NZ residential build. Actual timelines vary by site conditions, consenting authority, subcontractor availability, and weather. These figures are indicative only and should not be used for quoting.
Portal frame changes three numbers that matter to most builders: how fast the job closes in, how much margin is left at the end, and how much risk sits in consent and construction. Those gains come from the structural system, not from asking the crew to work harder.
Save 3-4 weeks
Frame goes up in days, not weeks. Faster enclosure means your crew and follow-on trades can keep moving instead of waiting for the structure to catch up.
Save 10-15% on Labour
The Truss House system is designed to speed up the entire build program from design, assembly, and time on site of sub-trades.
PS1 Certified
Pre-engineered and pre-certified. Fewer consent queries, fewer RFIs, and fewer on-site surprises. Your engineer starts from a verified structural basis instead of from scratch.
Based on completed NZ residential projects over multiple build cycles. Actual outcomes vary by project type, site conditions, and crew experience.
Choose the option that best meets the needs of your project. Same logic - different implementation.
Principle
The structural portal frame is the constant, pre-engineered element in the system. That repeatable frame helps deliver consistent build quality, structural safety, and efficient manufacturing from project to project.
Principle
The overall frame configuration can be adjusted to suit the project without changing the core structural logic. That gives developers and architects more room to shape different building types around the same system.
Principle
Because the portal frames carry the primary structural loads, the interior is free of load-bearing walls. That opens up a free-form interior where layouts can shift without fighting the structure.
Common questions by role
No. You can install the Truss House system using standard tools, and no crane is required. The installation relies on the exact same principles as installing a standard roof truss, so no additional specialist skills are needed, and complete installation instructions are provided.
Not at all. Truss House is tested and consented to work on both concrete slabs and suspended floors. Furthermore, because the frame is so precisely engineered and accurate, you can confidently order standard window joinery in advance, rather than waiting to measure on-site.
Yes, the system can be assembled off-site and then moved to your site, giving you ultimate logistical flexibility.
Actually, it is the exact opposite. Truss House uses your existing supply chain and Frame and Truss fabricator. The integration of the system is fully covered by Pryda engineering sign-off and a PS1 certification. It has a proven track record with consented and delivered projects across New Zealand, Australia, and Canada.
Consenting is actually faster than a traditional build. Because each house truss system is pre-engineered and backed by a PS1, councils accept that more of the overall structure is covered by the PS1. This reduces both the council’s and builder’s liability, which significantly reduces the number of RFIs (Requests for Information) you will receive and speeds up the entire consenting process.
Electricians and plumbers report approximately 20% faster install time. The system includes a continuous internal service cavity, so there’s no drilling studs or searching for routes. This also reduces damage, callbacks, and site variability.
Yes — significantly so. The envelope performs approximately 55% better than H1 minimum requirements, which means warmer in winter, cooler in summer, lower energy bills, and quieter — which is great if you live near a road.
Aside from getting them into their new home weeks earlier, Truss House delivers massive energy performance benefits. You can tell your clients that their heating and cooling demand will be cut by approximately 60% compared to a standard code-compliant house. It creates a warmer, drier home with fewer mould issues, and despite looking like a normal house, it performs like a highly energy-efficient Passive House. You can follow the Passive House pathway to gain certification should your client want that. This is a premium product offered at a conventional build price.
Not at all. Truss House portal frames carry the primary structural loads, leaving the interior free of load-bearing walls. This allows you to easily design open-plan living areas, double-height spaces, or highly customized floor plans without fighting the underlying structure. The system gives you the freedom to design clear internal spans up to 6.6 metres wide and apex heights up to 5.8 metres.
The system is highly adaptable and scales perfectly from compact cabins and single-family homes to medium-density, multi-story townhouses. Architecturally, it accommodates a full range of forms including standard rectangular, L-shape, T-shape, or courtyard configurations. While it handles single and duo-pitch roofs efficiently, complex roof forms can also be explored around the core structural logic, though optimal manufacturing efficiency is achieved when modules follow a consistent grid.
Truss House significantly reduces your regulatory burden by providing pre-engineered components that come fully certified with a Pryda PS1 producer statement. This gives your engineer a verified structural basis right from the start, which helps address complex seismic and wind requirements without adding bespoke engineering costs. Ultimately, this simplifies compliance, drastically reduces the number of Requests for Information (RFIs) from the council, and accelerates the entire consenting process.
Yes, Truss House BIM and CAD models are available and can be seamlessly integrated into your current digital design suite. Furthermore, the system is engineered in collaboration with Pryda’s advanced software platforms, allowing for highly accurate detailing, precise load calculations, and a smooth transition of engineered components straight into fabrication documentation.
Truss House inherently delivers exceptional thermal performance. The building envelope performs approximately 55% better than H1 minimum requirements, easily achieving wall insulation values of around R6.0 and floor values around R6.3. This means your designs will deliver low-carbon, highly efficient homes that already meet the upcoming 2030 Building for Climate Change standards.
Yes, Truss House provides a predictable, cost-effective system that allows you to bridge the gap between imaginative design and efficient construction. By utilizing a repeatable framework that reduces design complexity, minimizes material waste, and dramatically cuts on-site labour times, it provides a financially feasible way to deliver high-quality, high-performance homes.
Absolutely. Because the portal frames handle the primary structural loads, the vast majority of interior walls remain non-load-bearing. This gives homeowners immense flexibility to rework internal layouts or open up spaces in the future without compromising the structural integrity of the base building.
The system drastically reduces construction timelines by shortening the structural stage. On multi-unit developments, these time savings repeat across each unit, allowing for earlier enclosure and faster service installations. Ultimately, this allows developers to compress months of work into weeks, demolishing traditional construction bottlenecks so you can bring handover forward and capture market opportunities much faster.
By significantly reducing on-site labour, compressing sequencing and access of subtrades, minimizing material waste, and shaving weeks off the construction schedule, Truss House leads to reduced contingency costs and far greater budget certainty.
Yes, it is exceptionally well-suited for multi-unit townhouse layouts and medium-density vertical projects. The system utilizes a “Flexi” principle, allowing the same core structural logic to be adapted and repeated across multiple dwellings. This consistency boosts manufacturing efficiency, dramatically simplifies site coordination, and provides developers with a highly predictable cost base per unit.
Trusting a builder’s interpretation to deliver exactly what was designed on-site carries significant financial and reputational risk. Truss House shifts that liability away from variable on-site construction to precision-engineered components manufactured in a controlled factory environment — not a new factory, but the same Frame and Truss plants your builders already use. We are shifting some of the work and liability from site into the F&T plant.
Absolutely. Large construction projects often suffer from complex logistical challenges and conflicting schedules between competing trades. Truss House transforms multi-trade interactions into a predictable, streamlined process. It turns a complex site into a highly choreographed performance where every trade knows exactly when and where they fit, minimizing coordination overhead and delays.
Truss House provides a genuine competitive advantage by delivering enhanced thermal performance, sustainability, and technological sophistication. It allows you to offer high-performance, low-carbon homes that save your home buyer up to 60% on heating and cooling costs — giving you a premium product at a conventional build price.
No, it actually simplifies it. Because every Truss House portal frame system is pre-engineered and comes fully supported with Pryda PS1 producer statement certification, it gives your engineering team a verified structural basis right from the start. This standardisation reduces grey areas, significantly simplifies regulatory compliance, and typically accelerates your approval timelines by reducing the number of council queries.
Not at all. The wooden portal frames are completely hidden inside your walls and ceiling. From both the outside and the inside, your home will look and feel like any other high-quality New Zealand build. While it performs at the level of a high performance house, it looks like a modern New Zealand home.
Yes, the system is exceptionally well-suited for custom interiors. Because the portal frames carry the primary structural loads of the house, the interior is free of load-bearing walls. Our Fixed, Flexi or Free options provide maximum flexibility.
Yes, significantly faster. The portal frame system can save around three to four weeks on a standard residential build. Because the frame goes up much faster and allows the house to be enclosed quicker, consenting is streamlined — all meaning you get your home sooner.
Absolutely. The system delivers massive energy performance benefits that will drastically reduce your ongoing running costs. It cuts heating and cooling demands by approximately 60% compared to a standard, code-compliant house.
Yes, it does. The enhanced energy performance creates a naturally warmer and drier home. This leads to far fewer issues with dampness and mould, resulting in a significantly healthier everyday living space.
Usually, yes. Because the main structural loads are carried by the portal frames, most of your interior walls will be non-load-bearing. This gives you much more flexibility to easily rework or open up the internal layout later on. While extending the footprint of the home still requires engineering input, the base structure gives you plenty of room to adapt your home as your needs change.
Yes, building with this system is a great way to future-proof your investment. Its high energy performance already meets the upcoming Building for Climate Change standards, ensuring your home remains compliant and highly valued well into the future.
Yes, we are working with NZGBC and our energy modelling team to provide the documentation you require to submit to the banks for lower interest rate sustainability linked home loans.
