We design smart stairs.
That means always bringing together form and function. Good, clean, modern design with precision manufacturing to ensure the right fit for your project. We source quality materials and manufacture exclusively from our purpose-built Adelaide facility. And our teams in Adelaide, Melbourne, Sydney and Brisbane are there to give you smart advice about the stairs you need.

We deliver fast stairs.
We’re constantly fine-tuning every part of our manufacturing, delivery and installation process to give our customers the fastest delivery, as well as a competitive price on a lasting product.

We know stairs.
We are a third generation Australian owned business, and we’ve always been practical types who’ve built things well. It started with our grandfather’s Adelaide hardware store, and our knowledge of timber led us to start building stairs nearly 40 years ago. Since then that’s all we’ve done.

We continue to introduce new stair options and designs, to make the process even faster, and offer the best range of stair parts.
