Steel Frame Designs is not a manufacturer or a builder. We're a design-led broker that exists for one reason:
We've spoken to dozens of owner-builders who waited months for quotes from fabricators — only to be ignored.
That's not your fault — it's how the industry works right now.
Fabricators are swamped. One-off granny flats and DIY builds simply don't justify the time it takes them to do engineering, detailing, and council-ready files.
That's where we come in.
Ensuring your ideas work with steel frame construction
Professional technical drawings for manufacturing
Structural calculations for your exact location
All documentation ready for building approval
Then we send complete files to our fabricator partners — and they press go.
Weeks, not months for quotes
No costly mistakes or rework
(because we've already done the work)
We don't just make steel frame kits.
We make them actually happen.
How we became the bridge between owner-builders and manufacturers
After years in the construction industry, we noticed a frustrating pattern. Owner-builders with legitimate projects were being ignored by steel frame manufacturers. Not because their projects weren't viable, but because the manufacturers didn't have time to handle the preliminary work.
The engineering, the council submissions, the design modifications — all the work that happens before manufacturing could even begin. For a one-off granny flat, it just wasn't economical for them to spend weeks on the paperwork.
We realized we could be the missing link. We handle all the complex preliminary work — the design review, engineering calculations, council documentation, and technical drawings. Then we package everything up for our manufacturing partners.
For manufacturers, it's easy — they receive complete, ready-to-build files. For owner-builders, it's finally possible to get their steel frame kit made without months of waiting.
No more waiting months for a response. We get back to owner-builders within 48 hours.
We know you're working with budgets and timelines. We speak your language, not industry jargon.
We make the technical stuff simple and the manufacturing possible.
