A well-designed timber deck can turn a basic backyard into a functional outdoor living space. Whether it’s for entertaining, relaxing or expanding your home’s footprint, decking is one of the most popular additions to Queensland homes. But before you start building, it’s important to understand what’s allowed, when you need council approval, and how to design a deck that lasts.
This guide will help homeowners in South East Queensland make informed decisions about timber decking, including approval requirements, design considerations, materials and costs.
Timber decks offer both lifestyle and property value benefits. They’re perfect for Queensland’s outdoor climate and can be tailored to suit a variety of home styles.
Benefits include: – Adds usable outdoor space – Improves home value and appeal – Provides a seamless indoor-outdoor transition – Versatile for dining, lounging or poolside use
In many cases, decks require building approval from a private certifier. However, some smaller, low-level decks may qualify as accepted development and not need formal approval. The key is understanding your local council’s planning scheme and the Building Regulation 2021.
A timber deck might be exempt from building approval if it: – Is under 10 square metres – Is less than 1 metre above natural ground level – Is not roofed or enclosed – Has no side longer than 5 metres – Is not attached to the house
Even when approval is not required, the deck must still comply with zoning, setbacks, and overlay requirements in your area.
You’ll likely need building approval if your deck: – Exceeds 10 square metres in area – Is more than 1 metre off the ground – Has any side longer than 5 metres – Is roofed or attached to your home – Is located in a character area, flood zone or heritage overlay
If the total cost of labour and materials exceeds $3,300, the deck must be built by a QBCC-licensed contractor.
Each SEQ council has its own rules. Common planning considerations include: – Minimum boundary setbacks (usually 1.5 metres) – Site cover limits (percentage of lot covered by buildings) – Siting codes for small lots – Heritage or neighbourhood character overlays
For sloping sites or unique zoning, additional approvals may be required. Always consult a private certifier or planning officer.
If your deck is more than 600 mm above ground level, it must include balustrades or handrails. Taller decks may require privacy screening or fire separation in certain areas.
