Sigma Build revolutionises construction by integrating sustainability into every modular solution. Born from James Energies – established in 1965 and recognised nationally for transportable switchrooms – Sigma Build represents a natural evolution of that industrial manufacturing heritage. Based in Heathwood, Queensland, the company operates from a 9,000-square-metre factory, combining decades of industrial precision with sustainable, prefabricated modular housing. Sigma Build designs to NatHERS 7-star standards as baseline, with ability to upgrade to full Passive House. The company's hybrid construction method uses a steel portal frame chassis with timber-framed modules, capturing approximately twelve tonnes of embodied CO₂ in the timber which offsets the steel frame. Projects have been delivered for QBuild and Stadiums Australia.
