I. How to Construct a Deck?

You can do it yourself: if you keep it basic, creating a timber deck isn’t that difficult. This tutorial is for you even if you have no prior knowledge of building. This will show you how to build a deck that is functional, cost-effective, and long-lasting. To design and build your own timber deck, you’ll need to follow six crucial stages.


Step 1: Conduct preliminary research

Research helps you to find useful alternatives in materials and procedures that might help you avoid problems on the road. Below, we’ve listed a few options for you to consider.

You should also do some research on the cost of creating a deck before you start. For that purpose, this website offers a useful (and free) Deck Cost Calculator. Use a lower per-square-meter rate because the calculation thinks you’ll hire a constructor.

Composite decking – a timber decking alternative

For many homes in bushfire-prone areas timber decking is not an option, due to its combustibility. If your home is in a bushfire-prone area or you want a maintenance-free timber deck you may like to try a timber composite product. These products are usually comprised of PCV, timber dust, and glue. An example of this is Timberlast decking. It is made of recycled HDPE and wood fiber. The Timberlast product is made to last and will not rot, splinter, or require painting or oiling. It is slip-resistant, fade-free, easy to install, and the product looks like regular timber decking. Composite decking products are also perfect for the DIYer.


Underdeck waterproofing

Waterproofing the bottom deck can be difficult in many houses with several decks built on top of one other. If a homeowner wished to waterproof a lower deck in the past, he or she would apply ‘Colorbond’ to the top deck’s underside. There are several drawbacks to this method: 1. Gutters were required to transport rainwater, and 2. the problem is now permanently resolved (so if something drops through the decking above it will be difficult to retrieve).

Step 2: The preliminary and final designs (to scale)

Before you start, make sure you have everything you need.

Sit down with your list of criteria, your visual study, and your house’s simple blueprint. The following step is the most difficult. To construct your deck, you must now consider all of these aspects in conjunction.

The greatest place to begin is with your deck’s sitting, or its position and orientation. The greatest location for your deck isn’t always where there’s a lot of open space. This is frequently the incorrect location, resulting in a deck that is rarely utilized.

Examine your needs list and ask yourself, “Where on my house plan is there space that satisfies my criteria?” You’ll probably discover that no area fulfills all of your needs right away, so start with the location that checks the majority of the boxes.



Orientation is crucial. A deck on the north to north/east side of your property is excellent for all seasons. This implies that it will receive enough sunlight from early morning (when the sun rises in the east) through the late afternoon (sun setting in the west). Decks on the south and west sides of your house will offer you temperature extremes in seasons when you don’t want them, and they may also make your house hotter by transmitting reflected heat into it


Place your deck away from your main living area. Examine where you spend most of your day. Usually, it’s in the family/kitchen area. If your deck is on a corner of your property, select the side with the best view, even if it has less room. Remember that a deck must be at least 2 meters deep to be used. Note that you may need to wrap the deck around a home corner.

Also, keep in mind that your deck cannot be closer than 1 meter to any side boundary fence. Consider privacy retention if you want to build your deck along a side boundary. Views into and out of your neighbor’s area should be considered because your deck will be not just near to the fence but also taller. Consult your neighbors about your plans, and if privacy is a concern, consider including a screen in the design. See our page on external privacy screens for more details.

Once you’ve chosen a place, double-check that there are no utilities such as plumbing or electricity flowing in the region.


You’re now ready to start creating your deck. On a copy of your house design, doodle a rough sketch of your deck. Take note of the position of doors and windows, as well as any easements and setbacks.

The following should be included in your plans:

  • Two scale dimensions of vertical and horizontal elements
  • Two scale dimensions of vertical and horizontal elements
  • Drawing detail including balustrading, steps, supporting post locations, or built-in seating
  • Balustrades are only required for decks with floor levels over 900mm above ground level. But for safety, it is wise to balustrade all decks higher than 1 meter
  • Avoid adding stairs to your deck unless you are up for a challenge

You may either design a deck yourself or hire a draftsperson to do it for you. If you don’t hire a draftsperson, you’ll have to consult an engineer to determine the size of the wood members you’ll need. Don’t worry, a basic deck shouldn’t be prohibitively pricey.

Step 3: Prepare the site

You will need to prepare the location after you have a clear strategy. Take note of any notable tree species or trees that are taller than 3 meters. Due to council limitations, these may need to be maintained. Consult your local government if you have any doubts. Decks may be built around trees, and they frequently look fantastic.

Clear the area of trees, shrubs, roots, and buildings, as well as mowing or removing grass. Clearing the site makes construction and set-up go more smoothly.


Step 4: Laying out space

1. Layout of the location

With a pencil, draw the length and location of the deck on the wall of your home. On the house cladding, you’ll need to indicate the completed level of the deck floor. To minimize waterproofing issues caused by heavy rain, the deck floor level should be at least 75mm lower than the internal floor level. There are methods to build a deck floor level that matches the inside floor level, allowing for a smooth entry, but this is best left to the pros.

2. Layout horizontally

To layout, the shape of your deck, use a string line to measure the depth of the deck against the house wall and place a timber stake in the ground at each corner. Each stake should have a string wrapped around it.

Make sure the deck is square now. Only one trigonometric calculation is required for a basic square deck. This will guarantee that your deck is at a 90-degree angle to the house. Enter the deck’s length and depth into the calculator. The hypotenuse will be calculated as a result of this. Confirm the position of the corner set-out stakes using the length, depth, and hypotenuse as shown in the picture above.

3. Layout vertically

The vertical completed deck level can be laid out after the horizontal set-out is complete. The vertical layout is crucial for ensuring a suitable drop down from the house to the deck. It serves as our beginning point. This vertical level will determine the height of all other deck parts, such as decking joists, whaling board (or ledger – it connects the house to the deck), bearers, and posts.

Prop up the long straight piece of wood against the house at a 90-degree angle along the string line, with the long straight piece of wood (95mm end) sitting vertically. Ascertain that the top of the timber matches the deck floor level marked on the house cladding. Hold the other end of the timber 90 degrees away from the house and use a spirit level to move it up and down until it is horizontal (the bubble in the level is in the center). Set the string line on this corner post to the appropriate height.

Do the same thing with the string line on the opposite side. You now have a plan for your completed deck level.

Step 5: Construction


1. Footings and holes for footings

Concrete pad footings are the most basic form of footing. Make square holes that are 350 x 350 mm broad and 450 mm deep. Fill the hole with enough dry concrete mix to fill it. Slowly pour in the water as directed on the concrete package. With a shovel, quickly mix the water and concrete until all of the dry concrete mixes are wet but not sloppy.

Place the post in the hole as the concrete begins to thicken, press it down as far as it will go, and hold it in place until it stands on its own. You must now work rapidly, as the concrete will begin to harden swiftly.

Hold your spirit level vertically on all four sides of the post to ensure it is perfectly upright. Move the post around until it’s completely straight on all sides (with the spirit level bubble in the middle). Ensure that your posts are aligned with each other by using a string line or a straight piece of wood to confirm their position during installation.

Allow your posts to lie undisturbed for at least an hour or until the concrete has hardened.

2. Putting the bearers in place.

Laying bearers can be done in two methods. The bearers can be connected to the side of the posts using structural bolts, or they can be notched into the posts with a chisel and then bolted into place. The first approach is simpler; it costs a bit more (for the bolts), but it’s adequate for a deck that’s only 300mm from the ground. The notching approach is used by most professional deck builders since it results in a higher-quality deck.

At least one bolt per post should be used to secure your bearer to the posts. (This will be noted on your engineer’s plans.) Begin with the closest post to the home.

Now take your spirit level and set it on top of the bearer, moving it up and down until it’s horizontal. Once the bearer is level, use the bolt to secure it to the last post. You can now simply fix all of the other carriers.

Note: If you want to tile your deck, you’ll need to create a fall from the house to the deck’s outer edge to keep rainfall out of your house.

3. Putting the joists in place.

The engineering plans will specify how often and where your joists should be laid on top of your bearers. Normally, joists are installed at 450mm centers across and on top of the bearers and then secured with galvanized connection plates. Prepare for the placement of the decking boards by spacing and fixing your joists as needed.

4. Laying the foundation


It takes a lot of patience to lay the deck. Consider renting a nail gun if you’re going to use nails. At each joist, you must nail the boards twice with the ridges down.

It’s a good idea to drill all ends of the boards and screw them down to the joists if you’re using wood that’s prone to a lot of movement and splitting.

If your deck isn’t shielded from the elements, you’ll need to leave a 5 to 10mm gap between the boards. You’ll need to use a spacer of some sort to keep the boards at the same distance apart.

You may certainly find purpose-made spacers at your local hardware shop, but you could just as easily use a bolt or a piece of wood with a thickness of 5 to 10mm.

Make sure your nails or screws are in the center of your decking board at all times. If required, use a string line.

A specialist should inspect the connection between your deck and the home entry to ensure that waterproofing concerns have been addressed.

5. Sealing or painting


It’s a good idea to cover the deck with something that will protect it from the sun, rain, and fungus. An oil-based treatment will improve the look of the wood, prevent it from splitting, and extend its life. The deck will, however, need to be recoated every year or two. Painting provides more protection for a longer length of time (up to 10 years).

Because there are so many different types of wood treatments on the market, it’s a good idea to seek professional assistance.

Step 6: Certification

Your deck will need to be reviewed by someone with technical or construction knowledge, regardless of who creates it. The best person to certify it is the engineer who created it.
