Factory precision, engineered strength, and keys in hand sooner.
Skip the build chaos. Secure your eco home.
Precision modular building delivered nationwide, ready for sustainable living with Australian engineering at its core.
Based in the Murraylands, our South Australian team delivers modern modular homes with consistent quality and reliable timelines. Directors Luke Angel and Marcus Rayner bring 45+ years of combined building and mining experience. As a registered Master Builders Association member, we back our workmanship and manage every step from design through to handover.
We build in a controlled factory while your site prep happens in parallel. That means clearer timelines, less disruption, and reduced weather risk.
We handle the lot: approvals support, transport, cranage or placement, final utility connections, compliance, and handover.
Choose floor plans, fixtures, and finishes that suit your lifestyle and site. Join modules for larger layouts, add bedrooms, or reconfigure living zones.
Durable steel skid bases and precision-engineered steel frames designed for transport and longevity. Our team fabricates frames using Framecad automated machinery with BlueScope TRUECORE® steel, known for its strength, durability, and corrosion resistance. Each structure is built for Australian conditions and can include engineering upgrades such as earthquake ratings where required.
Smart insulation, double glazing options, solar-ready designs, and upgrade packs to help meet 6–7 Star NCC energy efficiency requirements.
Our signature range of eco modular homes combines factory precision with energy-efficient design. Each build is customisable, solar-ready, and crafted from Australian-made materials for strength and sustainability. Whether you’re building your primary residence or an off-grid retreat, our modular approach ensures speed, quality, and long-term performance.
