ABOUT
It all starts with a solid base.
At Base Built Co., we believe that every home — and every community — begins with a strong foundation. Not just structurally, but in vision, values, and purpose."
Base Built Co. was founded on three core principles: good building, good living, and a deep commitment to Tasmania’s future. For us, a well-built home isn’t just about construction standards — it’s about creating environments that support long-term wellbeing, energy efficiency, and community resilience.
We take a considered, high-integrity approach to every project. That means building with foresight, using sustainable practices, and designing spaces that feel as good to live in as they are functional to maintain. We work closely with trusted partners, experienced trades, and forward-thinking professionals to ensure every home we deliver is a lasting asset — for individuals, families, and the broader region.
In a fast-moving world, we build with intention. We invest in the base — because when the foundation is solid, everything else follows.
