Check out the Timber Decking Design Guide by WoodSolutions, an industry initiative designed to provide independent, non-proprietary information about timber and wood products to professionals and companies involved in building design and construction.
This guide outlines key design and construction considerations for light domestic timber decks for both raised and close to or on-ground timber decks that are exposed to the weather. It covers decks that are associated with Class 1 structures (such as detached houses, villas and townhouses) and Class 10 structures (such as garages, sheds and swimming pools) according to the National Construction Code (NCC) Volume 2. For the design and construction of decks for commercial, industrial or marine applications, or where a deck has to take heavier loads such as tiles, spas or even vehicles, a structural engineer must be consulted.
