Our latest project in River Heads, Hervey Bay is now underway, managed by an owner-builder who has chosen a steel frame system for its prefabricated efficiency and ease of assembly on site.

In Queensland, steel framing is a popular choice - especially for its durability and resistance to termites, though it does require careful detailing to manage condensation and minimise thermal bridging. When thoughtfully designed, it delivers a precise and robust home. Another positive is that steel is recyclable at end of life, offering sustainability benefits across the building lifecycle.

And in true qld style, the shed & deck will be finished first, ready for those well-earned arvo beers overlooking beautiful K'gari.

Roof to go on this week before being wrapped and sealed for weathertightness...
