Explore steel frame homes in New South Wales

When you build with McDonald Jones, you get a team of home builders who know a thing or two about building steel frame homes that stand the test of time in Australia. We've been doing it for over 35 years, and we are proud to set the pace with our industry-leading Supaloc framing system. Made with Australian TRUECORE® steel, this system is exclusive to McDonald Jones single, two storey and split-level homes. 

What is a Steel Frame House?

Steel frame homes are constructed using beams and columns made from highly durable steel that are capable of withstanding tremendous loads. These frames are famed for their durability and weather resistance. Although steel frames have been popular for decades, modern steel frames are precision engineered to fit together perfectly like a puzzle, offering unprecedented stability and durability.

Advantages of Structural Steel Homes


Structural steel homes are resistant to termites and other pests that compromise timber structures over time. With a steel frame as the ‘skeletal structure’ of your home, you can expect to save significant amounts of money on maintenance and pest control.  

The Supaloc steel frames in our homes could save you thousands of dollars in maintenance and chemical termite treatments. Supaloc is not only 100% impermeable to termite damage, but the steel frames are also bolted into place ensuring virtually no movement for the life of the home.


The components of steel frames are bolted into place to ensure complete safety, even in the face of extreme Australian weather conditions. Unlike timber structures that can warp, rot and bend over years, a steel frame house remains structurally sound for generations.
