Built on engineering.
Not assumption
Expandable housing often looks similar online. The difference with Structra is engineering intent, specification control, and how well it holds up over time.
Engineered to Class 1A standards
CAT D Cyclone Options Available
Designed to achieve 7-Star NatHERS (site specific)
Built differently
Delivered faster.
- 10 - 12 weeks→ Eliminates delays and inconsistencies of traditional construction.
- 80% Factory built→ Factory built, final site connections only. Delays and trade dependancy limited.
- Installed in days→ Installed and weathertight in days - not months of site disruption or trade coordination
- Fixed cost→ Price locked at order. No weather varations, no trade shortages, no cost blowouts
Clear, upfront pricing.
Two engineering contexts
Same layout philosophy and interior finish options. Different structural intent depending on deployment requirements.
One platform
Four configurations.
A single engineered footprint, adapted to suit different living requirements — from compact one-bedroom layouts through to multi-room configurations.

Quality, efficiency & flexibility
Structra™ VS Others
Structra™
- 7-Star NatHERS Star Rating
Independently assessed — lower energy bills and year-round comfort, built in
- Polyurethane Panel Construction
High R-value closed-cell foam — moisture resistant, thermally superior, built to last
- 2600mm Ceiling Height
Generous, airy living space — well above the industry standard
- AS/NZS Certified Electrical & Plumbing
Fully compliant wiring, switchboard, WELS & Watermark approved fixtures throughout
- Accessibility-Ready Interiors
Step-free shower, wider doorways — designed to NCC accessibility standards

Other Modular Homes
.svg)
No building code complianceCannot be used as a permanent residence in most councils — it’s a cabin, not a home
- No energy efficiency rating
No independent assessment — higher running costs, uncomfortable in extreme weather
- No certified wind rating
Unengineered for Australian wind and weather — structural risk over time
- Polystyrene (EPS) panels
Absorbs moisture over time, lower thermal performance, degrades faster
- Ceiling heights below 2400mm
Cramped proportions that feel temporary — not a space you want to live in long term
Why Structra
Looks similar online
Performs very differently.

Approval-ready by design
Not adapted later. Structured with a Class 1A design intent from the outset, with system layouts, materials, and documentation aligned to how real approvals are assessed.
.svg)
Engineered for Australian wind conditions
Not just rated — structurally considered from the outset. STR7D is engineered for CAT D cyclone regions, with reinforced framing and components designed for extreme environments.
.svg)
Permanent-use standard — not relocatable-grade
Built for ongoing occupancy, not temporary deployment. Designed, specified, and detailed to meet the expectations of a fixed residential dwelling.
.svg)
Residential-grade specification throughout
Double-glazed aluminium windows, integrated electrical systems, and full interior fit-out. Built to live in comfortably — not retrofitted to feel acceptable.
