    Exmouth building design with cyclone resilience built in

    Category 5 Building Designs is an Exmouth based studio specialising in building design for Wind Region D cyclonic regions. Every home and commercial project we draw is shaped by the realities of the North West Cape, from powerful cyclonic winds to salt air and scorching summers.

    Whether you are building a new home, extending for a growing family or planning a shed or commercial fit out, we take your ideas from a conversation to drawings that builders can price and the shire can approve.

    Why Wind Region D compliance matters in Exmouth

    Exmouth sits in one of the most cyclone prone corners of Australia. Building to Wind Region D compliance is not a luxury, it is the difference between a home that rides out the storm and one that does not.
