Bringing quality and grandeur to every build. The team at Trethowan know exactly how to make your home sophisticated, timeless, award worthy — and unmistakably yours.

Then To Now

Our Story

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.

Your Ideas, Your Needs

It's All About You

You know how some builders seem to build what they think you want? We do things differently.

The Trethowan team focus on bringing your vision to life, making sure we design and build exactly what you want.

We listen to your ideas, providing expert guidance and innovative suggestions based on your needs.

It’s who you are and how you want to live that we’re most interested in. We understand your home needs to work for you on an every day level, whilst representing your own style and personality. Which is why we go the extra mile to ensure that every detail fits perfectly.


We’re all about designing the perfect space, but we also believe your experience during the process is just as important.

Working together, you’ll have direct access to our skilled team who will help tailor every aspect of your home, from the initial architectural design right through to the final choice of finishes and features. Regular reviews will take place together, and you will always be kept informed throughout the construction process.

This personalised approach guarantees opportunities for open communication and transparent collaboration — delivering a home that’s unmistakably yours.
