When you hear “kit home,” you might think of a flat-pack from a hardware store. A BlueScope steel kit home is something entirely different. It’s a precision-engineered structural package, manufactured from Australian-made BlueScope steel, backed by a Lysaght 20-year warranty, and designed specifically for your site.
Why BlueScope Steel?
BlueScope is Australia’s largest steel manufacturer, and their products are engineered for Australian conditions. Every Shed Homes kit uses BlueScope steel because:
- Australian made - manufactured in Wollongong, NSW. Not imported steel of unknown quality.
- COLORBOND® steel cladding - 22 colours with proven performance in UV, rain, and coastal environments
- ZINCALUME® structural steel - zinc/aluminium alloy coating for long-term corrosion protection
- Lysaght 20-year warranty - on structural and cladding products
- Cyclone-rated options - engineered for C1 through C4 wind categories
What’s in a Kit?
A Shed Homes steel kit includes every structural component needed to erect the building shell:
- Portal frame: Hot-rolled or cold-formed steel columns and rafters with bolted knee connections
- Purlins: C or Z section purlins for roof support
- Girts: Wall framing members between columns
- Bracing: Rod or strap bracing as specified by your engineer
- Roof sheeting: COLORBOND® corrugated or Trimdek profile
- Wall cladding: COLORBOND® in your choice of 22 colours
- Flashings: Ridge, barge, corner, and window flashings
- Doors: Roller doors and/or personal access doors as specified
- Windows: Aluminium-framed windows to your design
- Fasteners: All structural bolts, nuts, washers, and tek screws
The Engineering Package
Every kit comes with a full engineering package stamped by a registered structural engineer. This isn’t a generic document - it’s calculated for your specific site conditions:
- Wind region and terrain category
- Soil classification from your geotechnical report
- Footing design and slab specifications
- Connection details for every structural joint
- Bracing layout and load paths
These drawings are what your council needs for Development Approval and what your trades need during construction. For owner builders, the engineering package is your construction bible - refer to your signed-off engineering drawings for all concrete slab, footing, and structural specifications.
3D Component Mapping
Shed Homes goes beyond standard engineering with interactive 3D component mapping. After your design is finalised, you receive online access to a complete 3D model of your building.
Every single component is identified - searchable by part number from the bill of materials. Click on a bolt and see its specification. Search a part number and the model highlights exactly where it goes in the structure. This level of detail, down to every screw and bracket, is what separates Shed Homes from generic kit suppliers.

COLORBOND® Colour Range
Choose from 22 standard COLORBOND® colours for your roof and wall cladding. Mix and match - a different roof colour to walls, feature walls in a contrasting shade, or a uniform look throughout. Popular combinations for shed homes include:
- Monument® roof with Surfmist® walls - contemporary dark/light contrast
- Basalt® roof with Shale Grey™ walls - clean, modern palette
- Woodland Grey® throughout - blends into bushland settings
- Classic Cream™ walls with Manor Red® roof - traditional homestead look
All COLORBOND® colours are backed by BlueScope’s warranty and rated for Australian UV conditions.
Kit Home vs Fully Built: The Cost Equation
A steel frame kit home typically costs 30–50% less than an equivalent fully built home. The saving comes from:
- Removing the builder’s margin (typically 20–35%)
- Owner-managed fitout - you choose your trades, materials, and finish level
- No builder delays - you control the timeline
- Staged payments - pay as you go rather than a fixed-price contract
The trade-off is your time and project management effort. For many acreage owners, especially those with trade experience or strong organisational skills, the savings make it worthwhile.
