WestState Building Group is a family-owned Western Australian building company specialising in custom steel-framed homes, residential developments and custom granny flats.
At WestState Building Group, we take on fewer projects so we can build them better. With direct builder involvement from concept to completion and a smarter steel-framed construction system, we deliver quality workmanship, clear communication and a carefully managed build from start to finish.

WestState Building Group offers a more personal way to build, with direct builder involvement, clear communication and a practical approach to custom steel-framed construction. From the first conversation through to handover, your project is planned with care and managed with accountability.
Your home is not one of hundreds being pushed through a system. We keep our workload controlled so each project receives the attention it deserves.
You deal directly with a builder who understands the details, decisions and challenges behind the finished home.
We specialise in custom designed new home builds and developments, second storey additions and granny flats, providing quality craftsmanship and attention to detail throughout every step of the building process.
Every detail matters, from the way a wall is framed to the way a final finish comes together. At WestState Building Group, we take the time to plan properly, build carefully and deliver work that feels considered, solid and made to last.
We are dedicated to building your dream with quality craftsmanship and attention to detail.
