Decks

Make sure your balustrades and railings measure up

In Queensland, we have strict requirements when it comes to balustrades.

Where a deck or balcony is one metre or higher above the ground, balustrades need to be at least one metre high.

For decks more than one metre above the ground, openings in balustrades, including decorative balustrades, cannot be greater than 125 millimetres.

If your deck is more than four metres above the ground, balustrades cannot have any climbable elements located between 150 millimetres and 760 millimetres from the floor.

Waterproofing requirements for doorways to decks and balconies

Water leakage below door openings has been a source of concern for the Queensland Building and Construction Commission (QBCC) and other state regulators for a number of years.

The Building Code of Australia’s adoption of ‘AS4654 Waterproofing membranes for external above-ground use – Part 1 Materials and Part 2 Design and installation’ means that building contractors working throughout Australia are provided with clear and consistent detailing requirements to eliminate water leakage in construction. This standard came into effect in Queensland back in May, 2013.
