Timber Sofa
A low outdoor sofa with solid stacked-timber arms. At every seat seam two stacked 6x6s carry the seat, flush with the arms front and back, so the timber look runs right across the front. The plan includes both sizes: the 83-inch sofa and the 59-inch loveseat, each with its own cut list, shopping list, PDF and 3D guide. Four cut lengths each, every screw checked in 3D.

- Pick #2 Prime boards and sight down each one. Take the straightest and grab one spare of each size.
- Treated pine comes wet. Stack the boards flat with scrap spacers between them, out of the sun, for 2–3 weeks before you cut. Dry boards don't shrink or twist after you build.
- Use screws labeled for treated lumber (most coated exterior screws are) and galvanized brackets.
- Sand the faces and edges smooth, then stain once the wood is dry. A cedar-tone stain gives it the honey look in the photos.
- Wear a dust mask when cutting and sanding treated wood, and never burn the scraps.

Good to know
What sizes are in the plan?
Both. The 3-seat sofa is 83 inches wide (16 boards, from $530 in pine) and the 2-seat loveseat 59 inches (14 boards, from $420). Both are 34½ inches deep and 22 inches tall.
Which cushions does it use?
One standard 24 × 24 deep-seat set per seat, bought ready-made: about $64 a seat for Hampton Bay CushionGuard, or about $112 for Sunbrella.
Can one person build it?
Mostly. Every timber but one can be lifted by one person. The sofa's top back beam is a single 83-inch 6x6, about 70 lb in wet pine, so setting the back takes two or three people (the loveseat's is 59 inches).
How heavy is it?
Very. Wet pressure-treated 6x6s weigh about 10 lb a foot, so each arm is over 100 lb in pine and about half that in cedar. Every single timber can be lifted by one person, but the finished piece can't: build it where it will live, and roll the arms upright on a moving blanket instead of lifting them.
Can I cut 6x6 timbers with ordinary tools?
Yes. A 7-1/4" circular saw cuts about 2-3/8" deep, so square a line around all four faces, cut each face, and finish the small core with a handsaw. It's slower than cutting 2x4s, so the plan has you cut one of each length first and check it.
What drives the 8-inch screws?
The plan uses FastenMaster TimberLOK screws, which come with their hex bit and need no pilot holes. FastenMaster recommends a 1/2" high-torque, low-speed drill; a strong impact driver usually works too.
Will pine timbers crack?
Pressure-treated 6x6s are sold wet, and they check (small cracks along the grain) as they dry. That's normal, doesn't weaken them, and suits the rustic look. Pick the straightest timbers in the pile and let them sit a couple of weeks before you stain.
