Origin Tera
Introducing the Origin Tera Energy-Efficient 70m² Minor Dwelling—a beautifully crafted home that combines timeless barn-style aesthetics with smart, sustainable design. With its iconic gable roof and open-plan layout, this compact home features two generous bedrooms and a light-filled living, kitchen, and dining area—all designed for comfort, functionality, and modern living. The exterior is fully customisable, allowing you to tailor the cladding and colours to suit your personal style.
Built using high-performance SIPs (Structural Insulated Panels), this home offers outstanding thermal efficiency, a faster build time, and a healthier, more comfortable interior environment. Recent government changes have made it easier than ever to build minor dwellings up to 70m² without a full building consent—provided the home meets key criteria. We'll guide you through the process, from design to delivery, to help you unlock the full potential of your site with a home that's as efficient as it is elegant..
