With a DIY outdoor sectional on your patio, deck, or anywhere in your backyard, you’ll have fun entertaining or just stretching out and relaxing. This outdoor sectional comfortably seats four to five people on durable, all-weather outdoor-friendly cushions in a sturdy wooden frame. Best of all, if you’re good with an electric miter saw and a drill, the entire outdoor sectional is made solely with two-by-fours and one-by-twos, and the project takes just a day or two.
Before You Begin
This outdoor sectional is composed of two pieces constructed separately: a sofa and a sectional add-on. Upon completion, they are attached with metal interlocking furniture connectors.
- Sofa: The sofa is a full-size 77-inch long wooden frame with arms on both sides. It can be used by itself if desired since it’s not dependent on the other section.
- Sectional Add-On: The sectional add-on is nearly a duplicate of the sofa. The difference is that there is no arm on the left side since the left side connects to the sofa.
This project is based on two-by-fours made of Prime Whitewood, Southern Yellow Pine, Douglas Fir, or Hem-Fir—all standard two-by-fours available at most home centers and lumber yards for $4 to $6 per piece. All need to be coated for better durability.
Cedar two-by-fours are another option for the outdoor sectional. Cedar starts with a light reddish pink color, then soon weathers to an attractive silver-gray. Imbued with natural oils, cedar does not need preservatives. Cedar costs two to three times more than the other two-by-fours.
Wear eye and breathing protection when cutting the wood with the electric saw. Use a dust containment system, as well. Observe all safety precautions when operating the electric miter saw.
