This project was built and designed by Jonny from Jonny Builds. It’s a sleek, modern outdoor sofa finished with the traditional shou sugi ban technique to enhance weather resistance and style.
Jonny focuses on simple construction, minimal tools, and clean lines—making this project perfect for beginners and weekend woodworkers alike. The sofa is made from common home center lumber and can be completed in a day.

Clean Design with Practical Materials
The sofa’s minimalist design features wide, flat armrests and straightforward joinery. Jonny uses common dimensional lumber that’s both affordable and easy to find, keeping the project accessible and budget-friendly.
For those with a planer, smoothing the boards and removing the rounded factory edges improves the finished look. But this step is optional—Jonny notes that even without planing, the build will still come together cleanly.
Building the Frame
Construction starts with the armrest assemblies. These upright sections are joined with glue and screws, then finished with dowel plugs to hide fasteners and keep the surface clean.
Support blocks are added below the seat and between the arms for stability. These are attached with glue and brad nails or screws depending on what tools you have available. The rest of the frame is built out with pocket-hole joinery for added strength.
Installing the Seat and Backrest
Wide panels are cut to form the seat, which spans the full frame and rests on cross supports. These boards are attached with fasteners and glue to create a firm, sag-free seating area.
Backrest supports are cut at a slight angle to allow for a relaxed lean. The backrest panels are attached directly to these supports with brad nails and glue. For added detail, Jonny fills the visible holes with dowel plugs and sands them flush.
Applying the Shou Sugi Ban Finish
One of the standout features of this project is the shou sugi ban finish. This traditional Japanese method involves lightly charring the wood’s surface with a propane torch to increase durability and create a striking, textured look.
Jonny goes for a medium char, skipping the deep “alligator skin” texture in favor of a smoother feel. After torching, the wood is brushed with a wire brush to remove loose ash and then sanded by hand for evenness.
Sealing and Protecting the Charred Wood
Once sanded, the sofa is sealed with multiple coats of wipe-on polyurethane. This clear finish penetrates the wood and enhances the contrast between the charred and unburned areas.
The result is a durable, water-resistant surface that can handle outdoor exposure. It also gives the piece a rich, rustic-modern aesthetic that stands out in any backyard setup.
Simple Tools, Solid Results
Jonny intentionally keeps the tool list short to make the project more accessible. Key tools include a miter saw for angled cuts, a drill for pocket holes, a brad nailer, and optionally a planer.
He uses dowel plugs to cover screw holes, showing how small steps can make a big difference in the final presentation. These details help give the sofa a professional appearance without increasing the complexity of the build.
Versatile and Comfortable
The modern design of the sofa fits a wide range of outdoor styles, from urban patios to rustic decks. It can be used with or without cushions depending on your needs, though Jonny recommends adding outdoor cushions for extra comfort.
The sturdy frame and angled backrest make the sofa comfortable for lounging while also maintaining structure over time. The simplicity of the design means it can be easily scaled up or paired with matching outdoor furniture.
Free Plans and Video Guide
To make the project even easier, Jonny offers free SketchUp plans. These show all key dimensions and help visualize the build step by step.
Whether you’re working from the video, the plans, or both, the guidance is clear and beginner-friendly. The sofa is designed to be built in a single day, making it an ideal weekend woodworking project.
A Great Outdoor Project for Any Skill Level
This outdoor sofa is a perfect example of how simple techniques and thoughtful design can create something special. The shou sugi ban finish adds a layer of artistry and durability, while the frame is strong enough for regular use.
Jonny’s project strikes a great balance between form and function. It’s a fun, rewarding build that produces a piece you’ll enjoy for years to come.
