Versatile Steel Sheds for Liveable Spaces
Our steel sheds are Class 10a certified but can be incorporated into Class 1a structures when designed and approved accordingly. They provide a strong, adaptable shell for a range of liveable uses—granny flats, tiny homes, shed houses, or games rooms. While we don’t offer internal fit-out services ourselves, we’re happy to connect you with trusted professionals.
Engineered for Strength and Stability
Built from high-grade structural steel, our sheds feature:
-
Welded roof trusses for long-term rigidity
-
SHS columns for superior load-bearing support
-
Bolted connections for secure assembly
Unlike conventional C-section sheds that may flex, our robust design allows wall frames to be securely fixed to the columns—ideal for residential conversions.
Ready for Your Vision
Whether you're planning a:
-
Granny flat or compact tiny home
-
Shed house with full amenities
-
Recreational games room or studio
We can refer you to experienced tradespeople who specialise in fit-outs, so you can bring your space to life.
Simplified Approvals and Documentation
We can refer you to companies that can help you with:
-
Architectural drawings and site classifications/drawings
-
BAL (Bushfire Attack Level) assessments
-
Energy efficiency reports

Additional engineering documentation etc.
Internal Fitouts
