Adding a deck to your back garden is a dream for many homeowners. A deck can turn a bland outdoor area into the perfect space for entertaining; the perfect place for lounging in the sun and BBQs. And, you’ll not only increase your home’s floor space but with the right deck, you can also increase the value of your home.
Installing a deck requires some planning. There are government regulations to be followed, and decisions to be made about the type, size and materials used in your deck. All of these factors will impact the overall cost.
So how much does building a deck cost? Here’s a breakdown of the cost of materials and installation which will give you a good idea of the final deck price.
The size and shape of your deck
When it comes to the cost of the deck, the size, the materials used and shape of the deck will be a significant factor in the final price.
Having a deck professionally built in Perth, Western Australia costs $200/m2 on average with a small deck between 10m2 – 20m2 costing around $4,000, a mid-size deck around $7,000 and a large deck 50m2+, costing on average $9,000.
Decks that have a unique shape, e.g., those with rounded edges or built around existing fixtures in the garden, will cost more than a standard squared deck.
How much does it cost to build a timber deck?
The cost of a timber deck varies depending on the type of wood used. You can expect to pay around $160/m2 for a basic treated pine decking and more than $280/m2 for an Australian hardwood timber decking.
It is important to note that timber decking requires ongoing maintenance as UV rays from the sun can fade and dry out the timber, causing it to warp, split and crack. Too much water in the timber will cause it to decay and allow fungal infection and rot to take over, as will too much dirt.
These issues can be fixed by staining your deck, applying a deck oil or painting it. This is something you will have to do every 12 – 24 months.
Even though a “cheaper” option such as pine timber may look like the way to go, it can require costly maintenance, as opposed to a wood, like Merbau (which is a lot harder wearing and just as sustainable). So, keep this in mind when deciding on what material you think is best.
How much does it cost to build a composite deck?
Composite decking provides a great value proposition, especially in the long-term, as after installation, composite decks don’t need expensive upkeep in the same way timber decks do.
Composite decks are made from a combination of recycled timber fibres and plastic. This material is durable and waterproof making it an excellent choice for decking.
The average cost to install a basic composite deck starts at $170/m2 and goes up to $350/m2 or more, depending on the brand. Some of the most popular brands include Trex decking, NewTechWood, Timbertech, Modwood, and Millboard, each with a different price point and features.
Trex decking is widely considered one of the best composite decking materials in the world. Highly resistant to mould, scratching, fading and staining, the higher initial cost is quickly offset by the reduced maintenance costs over its 25-year guaranteed life.
Accessories, extras and “hidden” costs
Decking not only comes in different shapes, sizes and materials but can also be made unique to your style.
Raised or sloped decking can add considerable costs to your deck. A raised deck will also need to be fenced and have stairs leading to the garden.
You may also need to account for additional labour costs. These can increase by having a garden that is hard to access with specialist equipment, issues with services such as gas or water lines or the need for scaffolding.
Summary
When you’re in the market for a deck, the cost involved can vary significantly. However, a standard small-sized composite deck will start around $4,000 from planning to installation. While a large, roofed deck made from the highest quality hardwood timber could set you back as much as $25,000.
