The Benefits of DIY Decking

Let’s start by exploring why DIY decking is such a great project. A deck can bring countless benefits to your home, enhancing your lifestyle and potentially increasing your property’s value. It’s a versatile addition that can serve various purposes, from a cosy place to relax to an outdoor dining area, perfect for summer barbecues. With a vast range of decking boards available, you can customise your design to your specific preferences, and nothing quite beats the sense of achievement that comes from creating something with your own hands.

Decking in Garden Ideas and its Benefits

Decking: A Natural Addition to Your Garden

Decking offers a seamless transition from the inside of your home to your garden, providing a firm and level area that’s perfect for garden furniture. With a decking area, your garden becomes an extension of your living space, offering more opportunities for outdoor activities. Whether it’s sunbathing, dining, or stargazing, a deck enhances your garden’s overall functionality and aesthetic appeal.

The Benefits of Composite Decking Material

Composite decking is an excellent choice for any DIY decking project. Not only is it durable and low-maintenance, but it also offers various colours and finishes that can suit any design preference. Composite decking is a product made from a combination of wood and plastic. It combines the natural beauty and warmth of timber with the durability and resistance to the elements that plastic offers.

Composite decking is also environmentally friendly. The materials are often recycled, making composite decking a greener choice than traditional timber. Additionally, it doesn’t require staining or sealing, so you save time and money on maintenance.

Planning Your DIY Decking Project

Assessing Your Outdoor Space

Your outdoor area is the canvas for your deck, and you need to know its exact dimensions. This knowledge will help you determine how much material you’ll need and will influence your deck’s design. For an accurately levelled deck, the ground it is built must be flat and solid, preferably concrete.

Choosing the Right Timber

Decking kits offer an array of timber options. From the deep, rich colour of selectively forested Australian eucalypt hardwood to the durability of merbau and Kapur, there’s a wood to suit every aesthetic and budget.

When choosing your timber, consider both the colour and the density rating. For instance, Australian eucalypt hardwood from NSW and QLD offers an excellent toughness rating and a durability class 1, meaning it’s highly resistant to wear and tear.

Designing Your Deck

The design of your deck is not merely about the shape and size but also the layout of the boards, the spaces you leave between them, and the overall structure, including posts, bearers, and joists. Decking kits simplify this process, offering pre-designed options to suit various spaces.

Building Your DIY Deck

Preparing Your Area

Once your design and materials are ready, it’s time to prepare your area. Clear the ground, ensuring it’s free from debris and is level. If you’re working on grass or soil, you may need to lay a concrete foundation for added stability.

Setting Up Your Deck Frame

Next, set up your deck frame. Using the posts, bearers, and joists, build a robust structure that will support the weight of your decking boards. This process is crucial for the longevity and safety of your deck.

Installing Your Decking Boards

Now you’re ready to install your decking boards. Begin at one end, securing each panel to the frame with decking screws. The process will be more straightforward if you’re using a DAR decking board due to its finished, dressed-all-round profile.

Finishing Your DIY Deck

Applying the Final Touches

Once all your boards are secured, check for protruding screws and ensure all panels are firmly in place. If you’re working with a hardwood, consider applying a stain or oil to enhance the timber’s natural colour and offer further protection against the elements.

Adding Additional Elements

With the basic structure in place, you can now add the elements that will make your deck uniquely yours. Think about lighting, furniture, and plants to create your desired atmosphere.


DIY decking is a rewarding project that can significantly improve your outdoor space. With careful planning, a good understanding of the process, and suitable materials, you can create a high-quality deck that you and your family will enjoy for many years. Whether you opt for a DIY decking kit or build from scratch, there’s no better time than now to start your DIY decking journey.
