Think of your composite decking as an extension of your home. You want your indoor space to be stylish and functional, so why not apply the same principles to your garden?

We’ll show you how to achieve a usable and great-looking space with our timber deck design guide. In it, you’ll find some of our top composite decking design ideas to elevate your outdoor space.

Benefits of composite timber decking

Let’s start our timber deck design guide by understanding the benefits of composite timber decking, which is a blend of recycled wood and plastic, held together by bonding agents.

Straight away, this makes it more environmentally friendly when compared to wood, as it makes use of materials that are already out there.

One of the main benefits of composite timber is that it’s also far more durable, lasting for up to 20 years compared to around six years maximum for timber.

This is due to its robust composition — it’s resistant to water, fading, insect damage, warping and splitting. It also requires minimal maintenance — all you need to do to keep it in great shape is wash it occasionally with mild detergent and water, and pressure wash it annually.

That’s why it makes the ideal choice for your outdoor projects like your timber deck.
