I am excited to show you how to build this DIY Farmhouse Bench with 2×4 lumber. It is a very cheap and easy build.
This bench is 76 inches long, and can easily seat 4 adults. It is the perfect bench for anywhere in your house, or even outside. I’m using mine in my entryway, but it would also look adorable next to a dining room table, or imagine it out back by the firepit. A firepit bench is definitely next on my list.
Oh, and did I mention it cost less than $20 in lumber? Yeah, that’s pretty awesome!
7- 2×4 studs
2.5 inch grabber screws
2.5 inch pocket hole screws (if you are using your bench outdoors, you’ll want to get these ones because they are more weather proof)
Stain or Paint (see below for the kind I used)
Compound Miter Saw
Sander and 150 grit sandpaper
Drill and Impact Driver
Measuring Tape (this measuring tape with fractional markings is a life saver for me! I love it!)
Eye and Hearing Protection
4- 2×4’s @ 76 inches
2- 2×4’s @ 14 inches
1- 2×4 @ 58 inches
1- 2×4 @ 54 inches
4- 2×4’s @ 15.5 inches. Both ends cut at 10 degrees off square. Ends are parallel- drill pocket holes in one end of each board)
2 – 2×4 @ 12.5 inches. Both ends cut at 10 degrees off square. Ends are not parallel. (12.5″ from long point to long point)- drill pocket holes in both ends of each board.
2 – 2×4 @ 13 3/8 inches. Both ends cut at 45 degrees off square. Ends ARE parallel- drill pocket holes in the ends of both boards.
Build your legs.
For each leg, you’ll need your 15.5 inch boards, one 14 inch board, and one 12.5 inch board. Use your Kreg Jig to drill your pocket holes in the ends (see cut list).
Measure in 1 1/2″ on each end of the 14 inch board- this will be your top support piece. Apply some wood glue to your joint, and attach your legs to the top support piece using 2 1/2″ pocket hole screws.
Add cross supports to legs
Measure 2″ from the bottom of your legs. Apply some wood glue to your joint, and attach your cross bar using 2 1/2″ pocket hole screws.
This is what your legs should look like once they are assembled.
Build bench frame
After you’ve got your legs built, you will use your 58 inch board (on top) and 54 inch board (on bottom) to build your bench frame. Make sure to use wood glue and attach your cross bars using 2 1/2″ pocket hole screws.
Add diagonal supports to frame
PLEASE NOTE: This step is not pictured, but you can see the diagonal supports in the finished photos.
You’ll also need two 13 3/8 boards, which will be your diagonal supports. They stretch diagonally from the upper stretcher, to the cross bar on the legs. You will attach your diagonal supports using wood glue and 2 1/2″ pocket hole screws.
Assemble bench seat
Next, you’ll assemble your bench seat using 4- 72″ 2×4’s . You don’t have to hook the boards together, but I wanted mine super sturdy, since I have 3 kids who will do their best to ruin this bench. So I used wood glue and my Kreg Jig to plank the 2×4’s together.
Putty and Sand
After you’ve got your top and your bottom assembled, fill in any holes with wood filler (make sure you get the stainable kind if you are planning on staining). If you want the bench to look really sleek and smooth, you can putty or caulk the joints on your bench. I wanted mine to look more rustic, so I skipped the caulking. Once the glue, putty, and caulk is dry, take your sander and sand everything smooth. I made sure to round the corners on my bench too.
Finish the bench
Since I wanted a farmhouse look. I stained the top and painted the bottom of my bench white.
I used a wipe on poly to finish the wood and add some durability.
Then I took my sander and lightly distressed the edges of my bottom. My husband hates when I do this, but I know that after I put this much work into the bench, I would cry the first time my kids chipped or scratched it. So I beat them to the punch. Plus, I think it looks cuter distressed, and it’s my bench, so I get to decide.
Attach bench seat to legs
Once your pieces are stained and painted, you’ll use some grabber screws and attach your legs to your bench top, from the underside. (I didn’t fill the holes that face the wall, or on the underside, since nobody will see them.)
All in all, this project only cost me about $20 in lumber. And it only took me 2 afternoons from start to finish, which included a trip to Home Depot, drying time, and doing all the necessary mom stuff, like feeding children and taking them to school.
And doesn’t it look fabulous in my entryway? It is the perfect mix of sleek lines and rustic, farmhouse charm.
For $20, this DIY farmhouse bench is a project you should definitely tackle this weekend. You could even let your husband help if you want.
