In Queensland it depends where you live. If you are in a cyclonic area any exterior structure requires a building approval. In other parts of Queensland a deck (without a roof) can fall under the self assessable category if:
- It is a plan area of less that 10 metres square
- It is less than 2.4 metres high and the floor height from ground level is less than 1 metre
- Is not longer that 5 metres on any side
It is best to check with us or your local authority if you are unsure. Simply send your plans to us and we can let you know.
