This project was built and designed by Jonny from Jonny Builds. It’s a modern, space-friendly sofa made entirely from 2x4s and a few essential tools.
With a clean look and angled design, it works well both indoors and outdoors. If you’re interested in making your own furniture, this is a straightforward and rewarding build.

Why This Sofa Is Worth Making
A well-built sofa brings comfort, style, and functionality to any space. This version does all that while using affordable materials and simple joinery.
It’s ideal for patios, porches, or a minimal indoor setting. The angled structure gives it a modern edge without complicating the process.
Materials and Planning
Jonny starts with 16 straight 2x4s. Choosing straight, knot-free boards makes a huge difference in how easily the sofa comes together.
Before making any cuts, Jonny lays out his plans to keep track of how each board will be used. Careful planning up front saves time later.
Cutting the Angled Pieces
Most of the cuts for this sofa are made at a 15-degree angle. The seat stretchers are cut into trapezoidal shapes that set the angle of the seat.
Jonny uses the first piece as a template for the others to ensure consistency. Repeatability is key for keeping the frame aligned and stable.
The vertical supports and armrests are cut into parallelograms. A stop block on the miter saw helps with making these pieces uniform.
Sanding and Pre-Finishing
Before any pieces are assembled, everything is sanded smooth. It’s easier to sand while the pieces are loose than after assembly.
A few coats of Danish oil protect the wood and bring out its natural grain. Pre-finishing also helps seal areas that will be hard to reach later.
Assembling the Sofa Frame
Jonny starts by positioning the armrests at the correct angle, using seat stretchers to check alignment. He attaches each layer using two-inch screws.
To avoid overlapping screw paths, he alternates the entry points at each joint. This small detail prevents cracking and makes the joints more solid.
Pre-drilling the holes keeps the ends of the boards from splitting. Each screw is carefully placed to keep the frame secure and square.
Final Layers and Structural Details
The top layer of boards is finished off with wooden plugs to hide screw heads. Each plug is glued, cut flush, and sanded smooth for a seamless finish.
Back stretchers are added to support the cushions. These pieces are cut to fit snugly and provide structure for the final look.
Adding Cushions
Once the sofa frame is complete, it’s ready for cushions. You can buy pre-made cushions or make your own to suit your space.
Because the frame is solid and the design is universal, it works in a wide variety of indoor and outdoor settings. The angled back and wide seat provide real comfort.
Time and Cost
This project can be completed in a weekend, even with a limited tool setup. The estimated material cost is around $70, not including cushions.
If you’re on a tighter budget, used cushions from local marketplaces are a great option. It’s a cost-effective build with a high-end look.
