Climate in Karratha

Karratha falls in Tropical (Zone 1): high humidity summer with a warm winter. We take local climate conditions into account, and the panelling can be selected to suit — 50 mm EPS (R = 1.315 m²K/W) is standard, with upgrades to 50 mm PU (R = 2.083), 75 mm PU (R = 3.125) or 50 mm Silica Rock (R = 1.25). For developed countries we recommend the Silica Rock panels.

Wind — Region D — Severe cyclonic

Karratha is in AS/NZS 1170.2 Region D — Severe cyclonic, the severe cyclone region on the far north-west coast of WA (Carnarvon to Port Hedland) (design wind speed V₅₀₀ ≈ 80 m/s). Buildings here have to meet the most demanding cyclonic wind requirements in Australia — engage a structural engineer familiar with Region D before you order, and tell us what they specify. Everything we build must meet, or exceed, your country's building codes.

Bushfire (BAL) considerations

Bushfire risk is generally lower in this tropical region, though dry-season grass fires can still occur and a BAL assessment may be required for rural lots. Wind is usually the bigger design issue here.

Delivery

Getting a home from China to Karratha

Each expandable home ships from Shenzhen in a 40' high-cube container, and two homes fit in one container. The nearest major container port to Karratha is Fremantle Port, about 1535 km away by road. We recommend budgeting around USD $1,000–$2,500 for shipping to your nearest port — this does not include customs charges and import taxes. You must hire a customs broker in your country, who should also help with logistics from the port to your site.
