Building your own deck
Deck building is one of my favourite DIY projects. But whenever I start planning one, I’m reminded of the head-scratching work required before I can start swinging a hammer. Over the years I’ve refined critical steps and fixed common gaffes. Here is my process, along with a few tips, to help you nail your deck building project from start to finish.
Start with a sketch
I start off every deck build by drawing the shape and proportion of the deck as well as the orientation of the decking. It’s helpful to include property landmarks: your house and doors, shed, fences, etc. I use graph paper to maintain scale.
Mind the overhang
When you finalise your deck size, shrink it by 38mm on all sides that don’t attach to a house. This will be the dimension of your deck framing. A 13mm skirt covers the framing and the deck boards will hang over that by 25mm.
