Timber decking design ideas: transforming outdoor spaces in 2025

Choosing what design to go with when installing a new deck can be tricky sometimes. A deck is a very popular choice among Australian homes, and for good reason.

They can transform a bland concrete slab thats doing nothing for your outdoor space into an entertaining space you can use year round.

At Eco Carpentry we often help our clients with the design process as many people have trouble choosing what design to go with.

People know they want timber decking but they get stuck on how to make it look really good and work with their existing space.

The thing is timber decking design has come a long way from the basic platforms we used to build. These days theres so many options and styles that it can actually be overwhelming.

But if you understand the basic principles you’ll feel confident going into your decision, I’ll walk you through them.

Multi level designs that actually work

One of the biggest trends we’re seeing is multi level timber decking. It means exactly what its sounds like, it’s decking with multiple different levels, this creates different areas for different activities.

Instead of one big flat deck you’re breaking it up into areas that flow together but serve different purposes and it really does make a difference to how the space feels and functions.

It may seem dramatic to have different stories to your deck but even small variations in levels can make a big difference to the overall look and feel to the space.

I saw a project recently where they had the main entertaining area at one level, then stepped down to a smaller intimate seating area, and then down again to a fire pit zone.

Each level was only about 300mm different but it created this amazing sense of flow and made a petty small back yard space feel way bigger and looked amazing.

The thing is you have to get the proportions right. Too many levels and it starts looking fussy, too few and you loose the impact. Usually three levels works best.

Also you don’t want the spaced between each level to be too big or too small, don’t make them awkward little steps people trip over and also not to big people have to lunge to get to the next one.

Budget wise, multi level decks do cost more then a simple single level, probably around 30-40% more depending on complexity. But the visual impact is usually worth it if you’ve got the space and the cash.

Mixing timber with other materials

Timber alone looks amazing and most people do prefer just timber alone. However if you love different or unique designs then you may want to consider mixing it with other materials can create impact.

Stone, concrete, steel and even composite materials can work well with timber if done thoughtfully.

Timber decking with concrete boarders is an option that looks great. The hard edges of the stone contrast nicely with the natural warmth of timber. It also helps to separate the different areas if you choose to do multilevel designs.

If you’re going for more of a contemporary look then steel framing and railings with timber decking is the way to go. You can paint the steel if it looks better with your homes design, but keeping the steel colour is also an option, weathering steel or even galvanised can look fantastic with the right timber species.

Curved and angled designs

Listen, some builders only like to work with straight edges when it comes to decking, but if you find the right builder who is great as what they do then a curved design looks amazing.

Curved timber decking can create some beautiful flowing designs that work really well with landscape features.

I’ve done curved decks that follow the edge of pools, wrap around mature trees or just create a more organic feel in gardens with lots of curved planting beds. The construction is definitely more complex then straight decks but the end result can be stunning and is well worth the extra time.

Angled designs are another option that can make a space feel more dynamic. Instead of everything being parallel to the house, try angling the deck boards or creating diamond patterns. Just remember that angled cuts mean more waste so remember that when you’re making your budget.

Privacy and screening solutions

A more common theme I’ve seen recently is the incorporation of privacy screens into deck design. Timber screening can be both functional and beautiful if designed well.

Vertical screening is the obvious choice but horizontal slat screens can look more contemporary and often provide better air flow.

The spaces between the slats are important. It affects both privacy and visual weight, closer spacing gives more privacy but can make the screen feel heavy.

Outdoor kitchens and entertaining areas

If you want your outdoor area to be an entertaining space, then including an outdoor kitchen is an impressive way to elevate your space.

An outdoor kitchen with timber decking is a really popular design choice, and for good reason. People want proper cooking facilities outdoors, not just a basic BBQ on wheels.

An important thing to mention when talking about outdoor kitchens on timber decks is getting the fire ratings and clearances right.

Timber decking around cooking areas needs special consideration for heat protection and grease management. Non combustible materials might also be required directly around cooking equipment.

Lighting integration from the start

Lighting can really transform your outdoor space, especially if you value your nighttime outdoors.

Good lighting can really change how your timber deck looks and functions after dark but it needs to be planned from the beginning. You cant just decide at the end you want some lights added.

Lighting under handrails and lights into step risers are good safety features. They also create a nice ambient effect. The trick is hiding the actual LED strips so you see the light effect but not the source.

Current trends

The thing is, trends come and go but good design principles stay constant. Focus on proportion, integration with your house and landscape and practical functionality over following every current trend.

At the end of the day, the best timber decking designs are the ones that feel like they belong in their setting and work well for how you actually live.

Don’t get too caught up in complex designs if a simple solution works better for your space and budget.
