Back in 2017, Liam Trethowan, a seasoned carpenter with a background in custom residential homes, extensions and large commercial projects, decided it was time to create something of his own. That bold step is how Trethowan Building started — and now we’re proud to be one of Albury Wodonga’s go-to builders for high-quality, bespoke builds.

Over the past few years, we’ve experienced rapid growth, taking on projects ranging in value from $20,000 to $2 million. As fully registered Master Builders, we’ve got the skills to manage and execute your project perfectly. We operate within a 120km radius of Albury Wodonga, specialising in custom-designed residential homes, major renovations, extensions, and bespoke commercial builds.

Trethowan Building is a family-run business, which means we’re all about creating lasting connections through the spaces we build. We’re proud to have a skilled team that has grown alongside our reputation.

Our roots in the Albury-Wodonga region go deep — it’s where we grew up and where we choose to build, enhancing the communities we know best. We understand local needs and design homes that make the most of our environment. Whether it’s a new family home or a multi-dwelling development, we ensure our builds are practical, beautiful, and sustainable.
