A raised deck in a backyard made up of eight sections of modular decking


Add more useable space and give your backyard a stylish, modern update by installing modular decking. It's simple to install – and best of all, you can do it yourself! Here's how.


1Gather your tools and materials

Below you'll find all of the tools and materials you'll need to complete this project.
Tools and materials needed to install modular decking.

2Measure and mark out your area

Before you do anything else, measure the area you'd like your deck to go and clear space around it. Head to your local Bunnings and pick up your modular decking system and make sure you have enough base and decking pieces to fill your designated space. If you're opting to make the deck yourself, choose the timber and have a team member cut it to size in-store – they'll even deliver it for you (but for this project we're opting for the easier modular system – you'll probably want to do this too).

3Screw your decking base kit together

This bit is surprisingly simple, as the kit comes with ready-drilled holes and pre-cut timber lengths. We used an impact driver drill to attach all our pieces – these are much more powerful than your regular drill (but also nosier – so use ear/eye protection). Attach with baton screws to keep everything in place.

4Lay everything out

Before you put everything together, make sure it's all going to fit, and that it's all level. This is where the feet you've bought will come in handy – they adjust to the level of your ground. To do this, bang them in with your hammer, and, once they're in place, you can wind them up or down to ensure your deck is level. If your ground is drastically uneven and your legs won't extend far enough down on one side, use pavers or bricks to jack up, then place your feet on top.

5Make sure everything's level again

We can't stress this enough – no one likes a wonky deck! Once you've attached your feet, use a spirit level to make sure it's all level again. Wait till the bubbles are central, and you're good to go. 

6Screw your deck frames together

Get your drill out and screw your frames together – create one big deck frame. Don't forget to wear your protective equipment for this bit!

7Lay your deck panels

This is the fun part! Lay your deck panels across the beams – they just slot in. It really is that simple! You can either choose to screw them in, or leave them loose and it will still be secure and safe. We decided to stagger the direction of our decking panels to add interest.

8Your modular deck is ready to use!

Once your panels are on, you're good to go! If you like, you may wish to give your deck a coat of oil, but this kit comes already treated and ready to go, so we left it as is. Simple! Now you're ready to wine and dine in style!

Health & Safety

Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page.

When following our advice in our D.I.Y. videos, make sure you use all equipment, including PPE, safely by following the manufacturer’s instructions. Check that the equipment is suitable for the task and that PPE fits properly. If you are unsure, hire an expert to do the job or talk to a Bunnings Team Member.
