Custom Home Builders and Extension Experts
We know building a home is one of the biggest investments you’ll ever make—financially, emotionally, and in time. Trust isn’t just important; it’s everything. At Thomsen & Hawthorn, we earn our clients’ trust by:
• Delivering what we promise – Our fixed-price contracts and clear timelines remove the stress of budget surprises and delays.
• Being transparent – From your first conversation with us through to handover, you’ll always know exactly where your project stands.
• Keeping you in the loop – With weekly site updates and regular check-ins, you’re never left guessing.
• Treating your home like our own – We don’t churn out volume builds. We take on select projects where we know we can add real value, attention, and quality.
• Building long-term relationships – Our past clients regularly refer friends and family—because they know we show up, do the work, and stand behind every build.
Our approach is personal, transparent, and grounded in craftsmanship. Here’s what that looks like for you:
1. We Listen Before We Build
Your ideas, lifestyle, and budget shape everything we do. We take the time to understand your vision, so the end result reflects your goals—not just our plans.
2. We Build with Integrity
From the first quote to the final handover, we’re upfront and honest. No cutting corners. No hidden costs. You’ll always know where your project stands.
3. We Care About the Details
Whether it’s a new home, renovation, or extension, we treat every project with the same care we’d give our own. That means high-quality materials, skilled tradespeople, and an eye for finish.
4. We Keep It Simple for You
Building can be complex—we make it easier. We manage the permits, scheduling, and site coordination so you don’t have to. You’ll always be informed, never overwhelmed.
5. We Stand Behind Our Work
We’re not just here for the build—we’re here for the long haul. Our workmanship is backed by real support after completion, because your peace of mind matters.

Mitch is the friendly face you’ll likely meet first. As our estimator and head of sales, Mitch is all about clear communication, upfront pricing, and making your building journey feel smooth from the very first conversation.

Director / construction Manager
Brendan Thomsen
Brendan is the hands-on leader behind the scenes—and often on-site-making sure every build is done to the highest standard. With a sharp eye for detail and a calm, solution-focused mindset, he ensures things stay on track and stress-free. When he’s not managing projects, you’ll find him off-grid with his wife and daughter, exploring Australia in their caravan, or spending quality time with extended family.

Jewel is the heart of our office. She keeps the wheels turning behind the
scenes—managing schedules, compliance, council communications and more—with
warmth and efficiency. Her diverse experience within the building/construction
industry and care make a big difference in every project. When she’s not keeping the
team organised, she’s with her granddaughter and extended family, or planning her
next travel adventure.

What They Say
Ben Como
THBS has recently added a 1st floor for us. Our primary objective was to increase the space and natural light in our house and we are very happy with the results. Our job was completed in a timely manner and when unexpected situations arose they were able to come up with solutions whilst still coming in on budget. I would be happy to recommend THBS.
Rod Bower
We engaged Mitch & Brendan to demolish our old asbestos garage and build a new one, do a bathroom renovation & instal a euro laundry. We moved the goal posts, in large ways, numerous times, however nothing was ever a problem for them. Brendan & Mitch delivered an extremely high level of workmanship, and their attention to detail and helpful advice has enhanced our build beyond our expectations.
