The 70 m2 SIPS Kitset is crafted for compact, efficient living where every square metre counts. With excellent insulation and durable construction, it creates a warm, low-maintenance home that’s fast to build and easy to manage. Perfect for secondary dwellings, granny flats, tiny homes, or short-stay units built to modern performance standards.
See how your home’s structure comes together foundations, walls, and roof panels installed in a streamlined, efficient sequence. Every kitset arrives flat-packed and ready to assemble. In just a few steps, you’ll have a strong, insulated shell ready for finishing.
Your site is prepared, and foundations are set, either piles or slab. Our SIPS system is designed to align perfectly with standard NZ foundations for quick setup.
All wall and roof panels arrive flat-packed, labelled, and weather-protected. Each kit includes everything you need, panels, fixings, and full installation drawings.
Pre-cut wall panels interlock using tongue-and-groove joints, creating a rigid structure and built-in insulation. No framing required, most wall sections stand within a single day.
Roof panels lock into place, forming a solid, high-performance envelope. Within days, your structure is weather-tight and ready for finishing.
The full SIPS shell is now enclosed and ready for cladding, windows, and interior fit-out. A faster, cleaner start to your build. All from a single delivery and within just 60 days.

drawings, R-values, panel details, connection details, and engineering specs, verified for NZ building standards.
