How Much Does It Cost To Build Your Own Decking?
If you get a quote from a builder the costs will be double to triple what your costs will be so doing it yourself can be an attractive project. With the money saved you could afford to buy better timber and better materials used to build the decking. The following examples are an estimate of the costs for varying deck sizes. Let’s assume your deck is either square or rectangle in size.
- 3 metre x 3 metre Raised Deck: Obviously the smaller the decking the cheaper it is. You don’t need as much timber decking, joists, bearers and posts. Do it yourself, you can build a raised deck attached to your home out of treated lumber for about $4000 in materials. Changing the decking material to Merbau would raise the cost.
- 4 metre x 5 metre Raised Deck: You could build a 4mx5m treated-lumber raised deck with stairs, for about $4,800 in materials.
- 5 metre x 5 metre Raised Deck: You can buy the materials for a 5mx5m deck using composite decking materials for about $5,500 and build it yourself.
- To build a 3 metre by 3 metre decking you will need 105 linear metres of timber and 19 5.7 metre FJ boards. To tie it all together will take about 480 screws.
