Holding up timber decks: Support options available

When constructing timber decks to the requirements of NZS 3604:2011, the deck must be supported on H5 125 x 125 mm square piles set in a concrete footing. Supporting a timber-framed deck on 100 x 100 mm posts is outside the scope of NZS 3604:2011. Where the deck using 100 x 100 mm posts requires a consent, the application must be submitted as an alternative method with sufficient information to show that it will comply with the New Zealand Building Code.
