Premium Quality, Uncompromising Compliance, Limitless Possibilities
Redefining Secondary Housing with Purpose-Built Excellence
In a market flooded with compromised imports and over-priced local alternatives, EVOHAVEN emerges as the gold standard for compliant, high-performance secondary dwellings. Engineered specifically for Australian and New Zealand regulations, EVOHAVEN delivers what others promise but fail to achieve: complete compliance, exceptional quality, and remarkable value.
Whether you're building a granny flat in suburban Melbourne, worker accommodation in rural Queensland, or eco-resort cabins in New Zealand's South Island, EVOHAVEN provides a turnkey solution that exceeds expectations while delivering 100% cost savings compared to locally manufactured equivalents.
Two Configurations, Infinite Applications
EVOHAVEN 20 (14 m²)
Compact, efficient, and perfect for tight urban sites or clustered developments. Ideal for home offices, studio granny flats, worker accommodation, or Airbnb units.
EVOHAVEN 40 (28 m²)
Spacious one-bedroom dwelling offering full amenities in a streamlined footprint. Perfect for primary granny flats, family compounds, farm stays, or premium glamping.
Both models ship as standard TEU containers (20-ft and 40-ft), ensuring lowest-cost freight and seamless delivery to any Australian or New Zealand port.

The EVOHAVEN Difference: Where Compliance Meets Craftsmanship
1. Structural Integrity That Stands the Test of Time
25-Year Structural Warranty
Built on ISO 1496-1 certified shipping container frames using 3 mm Corten steel (weathering steel), EVOHAVEN units are engineered to withstand:
Cyclonic winds up to Category 4 (AS 4055:2021 wind classification N4/C3)
Seismic activity per AS/NZS 1170.5 earthquake loads
Extreme temperatures from -40°C to +60°C
Heavy snow loads (up to 2.5 kPa live load)
Corrosive coastal environments (marine-grade steel with protective coatings)
Stackable to 5 Levels High
Our factory-welded corner castings and reinforced structure allow vertical stacking up to 5 units high (15 m), ideal for:
Multi-story worker accommodation
Urban infill apartment-style developments
Resort cabin complexes with tiered views
Mixed-use commercial/residential projects
Every structural modification is certified by third-party Australian engineers with AS 1684:2010 (timber framing), AS 4055:2021 (wind loads), and AS/NZS 1170.5 (seismic) compliance documentation.
2. Waterproofing Excellence: The Foundation of Quality
AS 3740:2021 Certified Wet Areas
Your biggest concern with imported housing? Waterproofing failures. EVOHAVEN eliminates this risk entirely.
Our Process:
Wolfin waterproofing membrane (German-engineered, 25-year warranty) applied to all wet areas
Bonded shower trays with integrated falls (no tiling required; eliminates grout failure)
1800 mm minimum height shower waterproofing (exceeds AS 3740:2021 requirements)
Factory flood-testing of every bathroom before container sealing
Third-party inspection reports and compliance certificates for council submission
Result: Zero water ingress, zero mould, zero callbacks. Council building surveyors can verify compliance through documentation—no invasive post-installation inspections required
Waterproof testing
3. Energy Performance That Exceeds Tomorrow's Standards Today
7-Star NatHERS Rating (Certified)

Light-colored exterior cladding (solar reflectance index >0.65)
Energy-efficient LED lighting throughout (9W downlights, dimmable)
HVAC Efficiency:
Split-system air conditioning (5-star energy rating, reverse-cycle heating)
Heat pump hot water system (COP 3.5+; replaces gas)
Solar-ready roof with pre-wired conduit and inverter space
Verified Performance:Independent NatHERS assessors certify every design, with reports suitable for council building permit applications across Australia and New Zealand.

The EVOHAVEN Value Proposition: 100% Cost Savings
While we don't disclose absolute pricing (project-specific), we transparently state:
EVOHAVEN delivers 100% cost savings vs. equivalent Australian/NZ locally manufactured models.
What This Means:
Tiny Homes Tasmania: Their 14 m² studio retails $80–100k+ installed. EVOHAVEN 20 delivers the same livable space, same compliance, superior finishes, for approximately half the cost.
Modscape/Anchor Homes/Swanbuild: Their 28–30 m² granny flats retail $180–280k installed. EVOHAVEN 40 matches or exceeds their specifications for 50–60% savings.
NZ Cabins/Pods: Kiwi-made 20 m² cabins retail NZ $120–180k. EVOHAVEN 40 (28 m²) offers more space, better fit-out, full compliance for comparable or lower total investment.
Why Can We Do This?
Factory efficiency: Chinese manufacturing scale + automation (vs. hand-built in Australia/NZ)
Material costs: Global sourcing of premium materials (same brands, lower wholesale costs)
No builder margin: Direct import eliminates 30–50% builder markup
Shipping optimization: Standard TEU containers = lowest global freight rates
What You Get:
Same compliance (NCC, NZ Building Code)
Same or better materials (GREENGUARD flooring, Wolfin waterproofing, Low-E glass)
Better warranty (25 years structural vs. 10 years typical local builds)
Faster delivery (16–24 weeks vs. 30–52 weeks local builders)
Built to Last: 25-Year Structural Warranty
EVOHAVEN backs every unit with an industry-leading 25-year structural warranty covering:
✅ Frame integrity: Corten steel container structure (rust-through, weld failures)✅ Roof weatherproofing: Factory-sealed roof membrane (leaks, penetrations)✅ Floor structure: Steel chassis and subfloor (sag, deflection)✅ Corner castings: ISO 1496-1 lifting/stacking points (fatigue, cracking)
What's NOT Covered (Standard Exclusions):
❌ Wear-and-tear finishes (flooring, paint, fixtures after 5 years)
❌ Damage from site installation errors (improper foundations, unapproved modifications)
❌ Acts of God beyond design limits (e.g., tsunamis, earthquakes >AS/NZS 1170.5 Zone 4)
Transferable Warranty: If you sell the property, warranty transfers to new owner (adds resale value).
