Prefab Extensions

Extending your house can bring the space your family needs and give you the lifestyle you desire.

Whether you’re building up or building out, a TBS prefab extension will add space and value to your house. Beyond space, an extension can provide long-term savings and environmental benefits in the years to come.

Our in-house design team and structural engineers will work with you to ensure that your house extension ticks all your boxes and blends beautifully with the elements of your local environment.

Extending your house with TBS will save you time, cost and inconvenience.


Due to our faster constructions times, you will experience reduced onsite tradie time, resulting in less disruption to your personal home life.

Your customised timber panels will be built in our factory and delivered directly to your property. Once the pre-work is done, moving from installation to lock-up stage only takes days.

With an extensive range of clients right across Australia, we have the capacity to deliver to just about any location within Australia and Overseas.
