Hello, I have a deck that is 800mm from the ground - so theoretically does not need balustrading. I want to put a fixed bench seat around the periphery - both for extra seating and as a physical barrier to prevent falling/tipping off deck.
This fixed seating would be 450mm from the deck floor ie 1250mm from ground height. I do not want to have to put a seat back on the bench seating.
Do I now need balustrading behind the bench seating to comply with building laws?
Thanks for the question and apologies for the delay in responding.
Since the fixed seating will be higher than 1 metre above ground level you will need balustrading on the bench seating as per the Building Code of Australia and AS/NZS 1170.1:2002 Structural design actions - Permanent, imposed and other actions.
Hope this helps.
