This step by step diy project is about 2×4 garden bench plans. This garden bench is built entirely from 2x4s, so it’s very simple to get the job done even for a beginner. Drill pilot holes before inserting the screws, to prevent the wood from splitting. You can easily adjust the width of the bench to suit your needs. Take a look over the rest of my woodworking plans, if you want to get more building inspiration.
When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. If you have all the materials and tools required for the project, you could get the job done in about a day. See all my Premium Plans HERE.

Building a 2×4 wooden bench
The first step is to build the front legs for the garden bench. Cut one end of the 2×4 slats at 85 degrees using a miter saw. Smooth the edges with sandpaper for a professional result.
Next, build the back legs for the 2×4 outdoor bench. Cut one end of the slats at 87 degrees and the other end at 67 degrees. Smooth the edges with sandpaper and remove the residues with a damp cloth.
You need to make an extra cut to the top of the back legs, as shown in the diagram. Mark the cut lines on the legs and get the job done with a saw.
Fit the 2×4 supports to the legs of the chair, so you can build the sides. Align the edges with attention, drill pilot holes through the supports and insert 2 1/2″ screws into the legs. Leave no gaps between the components for a professional result. In addition, add waterproof glue to the joints to enhance the rigidity of the frame.
See in this diagram more information for fitting the support properly. Align the edges with attention before inserting the screws.
Fit the 2×4 support to the front of the wooden bench. Align the support at both ends, drill pilot holes and insert 2 1/2″ screws to secure it into place tightly. Add waterproof glue to the joints for a durable bond.
Use 2×4 slats for the seat of the bench. Align the edges with attention, drill pilot holes and insert 2 1/2″ screws to secure the slats into place. Countersink the head of the screws for a neat result.
As you can easily notice in the plans, you need to rip one slat to 1 3/4″ so it can fit into place.
Continue the project by fitting the 2×4 support to the back of the bench. Drill pocket holes at both ends of the support and secure it to the top of the back legs using 2 1/2″ screws. Align the edges with attention and add glue to the joints for a durable bond.
Build the backrest for the bench from 2×4 lumber. Drill pocket holes as shown in the diagram and clamp the slats together, after aligning the edges with attention. Insert 2 1/2″ pocket screws to lock all the slats together tightly. Add waterproof glue between the slats for a professional result.
Fit the backrest into place, making sure you align the edges with attention. Drill pilot holes through the backrest support and insert 2 1/2″ screws into the slats.
Last but not least, you need to take care of the finishing touches. For a professional result, you need to fill the holes and the dents with wood putty. Smooth the surface with 120-220 grit sandpaper for a professional result.
Make sure you smooth the edges with sandpaper and apply a few coats of stain or paint to protect the components from the elements. Seal everything with a few coats of spar varnish.
This wooden bench would look best on a deck or backyard patio. It is sturdy and very inexpensive to build and all you need are a few tools and 2x4s. If you build these, I would love to see your project.
