Cost: About $165 (not including stain and polyurethane)
Time: About 4 hours
There’s no debate that all-weather outdoor furniture and accessories can cost a pretty penny—especially when shopping during the peak spring or summer season. Enter this clean-lined outdoor sofa. Made from inexpensive 2×4 boards, the project requires only a few basic tools. After you cut the lumber to size, pocket-hole joinery makes assembly quick and easy. For the cost of a few cushions—I found mine online for $35 per set (one seat and one back cushion)—and a few hours of work in the shop, you can have this comfortable couch for a fraction of what you’d pay in most stores.
Once assembled, stained, and protected with exterior polyurethane or paint, this sturdy outdoor sofa will let you focus on what matters most— entertaining friends and family—for many summers to come.
Building an Outdoor Sofa: Before You Begin
For this project I hand-selected the best-looking 2×4×8′ boards—sold as “studs”—from my home center. Using dimensional lumber is the most affordable option, but bear in mind that the boards come with rounded edges and grading stamps, so you’ll need to spend some time sanding to transform them into stain-grade stock. If you have access to a workshop, you can run the boards through a thickness planer or use a table saw to remove the rounded edges. You can substitute a naturally weather-resistant wood, such as cedar or cypress, but keep in mind that this would double the cost of the wood used in this project.
