How to Build a 2×4 Garden Bench

This step by step woodworking project is about how to build a garden bench. I designed this 48″ wide garden bench so you can build it using just 2x4s. In addition, you can make the matching chairs. so you can create a nice retreat corner in your backyard. The garden bench is easy to build and really sturdy, so you don;t have to worry about its durability.

We recommend you to invest in the best materials you could afford. Therefore, you should buy weather-resistant lumber, such as pine or cedar. Always take accurate measurements before adjusting the size of the components at the proper size. Drill pilot holes trough the components before inserting the wood screws, to prevent the wood from splitting.

2×4 Garden Bench Plans

Building the legs

Building the legs

The first step of the project is to build the legs for the garden bench. Mark the cut lines and get the job done with a circular saw. Smooth the cut edges with sandpaper for a professional result.

Assembling the sides

Assembling the sides

Continue the project by attaching the top support to the legs. Align the legs with attention, drill pilot holes and secure them together with 2 1/2″ screws. Add glue to the joints and remove the excess with a damp cloth.

Assembling the seat frame

Assembling the seat frame

Cut the components for the seat frame. Align the edges with attention, drill pilot holes through the front and back supports and insert 2 1/2″ screws. Add waterproof glue to the joints to enhance the bond of the components.

Assembling the garden bench frame

Assembling the garden bench frame

After building the sides for the bench and the seat frame, you need to assemble them together tightly. Drill pilot holes through the frame and insert 2 1/2″ screws into the frame. Use a spirit level to plumb the legs and to check if the seat frame is horizontal. Use a carpentry square to check if the corners are square.

Backrest supports

Backrest supports

Build the backrest supports from 2×4 lumber. Cut the exposed corner of the back supports in a decorative manner using a saw. Smooth the edges with sandpaper for a professional result.

Fitting the backrests supports

Fit the backrest supports to the bench frame, as shown in the image. Drill pilot holes through the bottom of the supports and insert 2 1/2″ screws. Add glue to the joints.

Attaching-the-seat-slats

Fit the 2×4 slats to the seat frame, making sure you place them equally spaced. Drill pilot holes before secure them to the frame with 2 1/2″ screws.

Fitting the backrests

Next, attach the 2×4 slats to the backrest. Drill pilot holes and secure them to the backrest supports using 2 1/2″ screws. Place a piece of 1/2″ plywood between the slats to create even gaps.

Attaching the armrests

Attaching the armrests

Build the armrests supports from 2×4 lumber. Round one end with a jigsaw and smooth the edges with sandpaper. Fit the armrests to the sides of the bench, drill pilot holes and secure them into place with 2 1/2″ screws.

Fill the holes with wood putty and let it dry out for several hours. Smooth the edges with sandpaper and then apply a few coats of paint or stain to enhance the look of the woodworking project.

 

 

How to Build a 2×4 Outdoor Bench

Building-the-legs-for-the-bench

First of all, I cut the components for the seat frame and drilled the pocket holes at both ends of the short components. I have not used 2x4s for this project, as I already had the slats laying around in my shop. These boards are wider and a little less thick than a 2×4, but the techniques used for building the bench are the same.

Building-the-seat-frame

After cutting the components, you need to assemble the seat frame. Align the edges flush and insert 2 1/2″ screws to lock the short supports to the long supports. Use a carpentry square to make sure the corners are right-angled.

Seat-Frame

Once you assemble the seat frame, it should look similar to mine.

Attaching-the-front-legs

The next step of the project was to attach the legs to the seat frame. Align everything with attention, using my diagrams. Drill pilot holes through the frame and insert 2 1/2″ screws into the legs. Add glue to the joints.

Attaching-the-back-legs

Fit the back legs to the frame, as well. Dill four pilot holes before locking everything with screws. Reinforce the rigidity of the joints with waterproof glue.

2x4-Bench-Frame

After attaching the four legs to the seat, the bench is starting to take its shape. You can use a spirit level to double check if the legs are plumb and if the seat is horizontal.

Back-rest-supports

Next, attach the backrest supports to the seat frame. Drill pilot holes through the bottom of the supports and insert 2 1/2″ screws into the seat frame.

Attaching-the-seat-slats

I continued the project by fitting the seat slats to the frame. I placed a spacer between the slats to create even gaps. I drilled pilot holes and then inserted screws to lock the tightly into place.

Backrest-supports

Continue the project by fitting the armrest supports to the top of the legs. Clamp the supports into place, drill pilot holes and insert 2 1/2″ screws to lock everything together. Add glue to the joints and align the edges flush.

Attaching-the-backrest-slats

I attached the slats to the backrest with 2 1/2″ screws. I aligned both ends of the slats and clamped them into place when drilling the pilot holes. I inserted the screws and made sure the head of the screws are under the surface.

Fitting-the-armrests

Next, I attached the armrests to the sides of the garden bench. I aligned the slats at both ends, drilled pilot holes and inserted 2 1/2″ screws to lock them into place tightly.

I used 120-220 grit sandpaper to smooth the edges before applying a few coats of teak stain. After the stain dried out I seal everything with spar varnish.

This project came out really nice and it is now used by all my friends. I like the nice and unique shape of the garden bench along with the straight-forwardness of the steps. In addition, the best thing about this project is that you can get the job done using just 2x4s. If you like my project, don’t forget to SHARE it on Facebook and Pinterest.
