June 7th, 2024 in Decking Blocks
Building your own deck can be a rewarding project, enhancing your outdoor space and adding value to your home. This step-by-step guide will walk you through the process, from planning to completion, ensuring you create a beautiful and durable deck.
Step 1: Planning and Designing Your Deck
Determine the Size and Location
First, decide where you want to build your deck and measure the area. Consider the following factors:
- Sunlight and Shade: Choose a spot that gets the desired amount of sunlight.
- Accessibility: Ensure easy access from your home and to your garden or yard.
- Utilities: Check for any underground utilities that may affect construction.
Design Your Deck
Sketch a rough design of your deck, including the layout, levels, and any additional features like stairs, railings, or built-in seating. Use design software or consult with a professional if needed.
Obtain Permits
Check with your local council or municipality to see if you need any permits for building a deck. Ensure your design complies with local building codes and regulations.

Step 3: Preparing the Site
Clear the Area
Remove any grass, plants, and debris from the construction area. Ensure the ground is level and firm.
Install Concrete Decking Blocks
Place concrete decking blocks at each corner and at regular intervals (every 800mm / 900mm) to support the joists. These blocks will lift the frame off the ground, preventing moisture damage and rot.
Step 4: Building the Frame
Cut the Joists
Cut the joists to the desired length according to your deck design. Use C16 joists for personal garden decking or C24 joists for heavy foot traffic.
Assemble the Frame
Lay out the outer frame on the concrete blocks and secure the corners with screws. Check that the frame is square by measuring diagonally from corner to corner.
Install the Joists
Place the joists inside the frame at 400mm to 600mm intervals, depending on the type of decking boards you are using. Secure the joists with screws and ensure they are level.
Step 5: Laying the Decking Boards
Prepare the Decking Boards
If using untreated timber, apply a wood treatment to protect against rot and decay. Allow the boards to dry before installation.
Lay the First Board
Start laying the decking boards from one corner of the frame. Use decking clamps or a couple of screws to hold the boards in place and ensure they are aligned correctly.
Secure the Boards
Use deck screws to secure each board to the joists, placing screws at each joist intersection. Leave a small gap (2-3mm) between each board to allow for expansion and drainage.
Continue Laying Boards
Continue laying and securing the decking boards, working your way across the frame. Trim any excess board length with a saw.
Step 6: Finishing Touches
Install the Edging
Attach edging boards around the perimeter of the deck to hide the ends of the decking boards and create a finished look.
Add Railings and Stairs
If your design includes railings or stairs, install these now. Ensure all railings are securely fastened and comply with local building codes for safety.
Treat and Seal the Deck
Apply a final coat of wood treatment or sealant to protect your deck from the elements. This will enhance its durability and maintain its appearance.
Step 7: Enjoy Your New Deck
Once the sealant has dried, your deck is ready to use. Add furniture, plants, and décor to create an inviting outdoor space for relaxation and entertainment.
Maintenance Tips
- Regular Cleaning: Sweep your deck regularly to remove debris and prevent staining.
- Annual Inspection: Check for loose boards, screws, or nails and tighten or replace as needed.
- Reapply Treatment: Reapply wood treatment or sealant every couple of years to maintain protection against the elements.
By following these steps, you can build a sturdy, beautiful deck that will enhance your outdoor living space for years to come. Happy building!
