Cairns' Wind Region C designation means all new homes must be engineered to withstand cyclonic wind loads significantly higher than those in southern states, roof connections, wall framing, and the entire structural system must be certified to regional wind speeds. Cairns builders familiar with the specific engineering requirements, materials, and inspection regime for Wind Region C construction are essential.
