Stairs designed online, built in our Victorian workshop

Stairbuilder is an Australian stair manufacturer based in Dandenong South, Victoria. We supply flat-packed, made-to-measure stair kits to builders, renovators and confident DIYers right across the country.

Every order starts in our 3D Stair Designer. You supply the floor-to-floor height and opening dimensions, choose your layout and materials, and the configurator prices the kit as you build it. Before anything is cut, our technical team reviews the design to confirm it can be manufactured and that it is set out in line with the National Construction Code.

What you get

Depending on your selection, a kit includes strings, treads, risers, posts, balusters, handrails, base rails, glue blocks, wedges, a pack of assembly fixings and installation instructions. Your Order Summary confirms exactly what is included before you pay.

Backed for seven years

We provide a 7-year warranty against defects in materials and manufacture from the date of delivery, in addition to your rights under Australian Consumer Law.
