DIY Window Box
You can actually see the 1×2 cleat in this pic from our Hand Painted Sign tutorial
So, let’s get started building! The printable plans are for one window box. If you plan to build multiple boxes, make sure to modify your supply list! Note: My plans and measurements are based on the size of my windows. Be sure to measure your own window and modify the plans accordingly!
I started by building the back frame first.
I cut the back frame pieces to size and used my Kreg Jig to drill 3/4″ pocket holes into the short, vertical pieces. You can find our favorite Kreg Jig HERE and make sure to check out our How to Use a Kreg Jig Video HERE!
Then, I attached the short pieces to the long pieces with 1 1/4″ pocket hole screws and wood glue.
Back frame assembled! I was building two window boxes so, I had two back frames!
I decided to use a pack of barn wood for the design. It is 1/4″ thick but you can use any type of wood that you want. You can find the barn woodthat I purchased HERE! Once the frames were assembled, I marked center on the back frame. Then, I measured and cut the first two long diagonal pieces to size and attached them to the back frame with 3/4″ pin nails and wood glue. The edges of the diagonal pieces should be flush with the edges of the back frame.
I cut the rest of the long pieces to the same size and attach them attached them with 3/4″ pin nails and wood glue.
Once the long diagonal pieces were attached, I moved on the to the ends and middle cuts. You can refer to the printable plans for the exact cuts and placement! This is what the barn wood pattern looks like once it’s complete!
Time to move on to the outside frame!
I cut the top and side, outside frame piece to size and drilled 3/4″ pocket holes in to the ends of the top piece. I attached the long piece to the short, side pieces with 1 1/4″ pocket hole screws and wood glue.
Here is the outside frame assembled! Time to attach it to the back frame! Also note the unfinished pieces at the back of my shop….there are at least 4 incomplete projects and they are on my to-do list!
I attached the outside frame to the back frame with 1 1/4″ brad nails and wood glue.
This is what the window box looks like at this point.
The final step in assembly was to attach the bottom frame piece. I measured and cut the bottom frame piece to size and attached it to the bottom of the window box with 1 1/4″ brad nails and wood glue. I had to use a 1×2 for the bottom trim piece to accommodate for the trim around my window. If you do not have trim on your window, you can just make a solid outside frame with a top and bottom 1×4 piece!
Because I was using barn wood, the barn wood did not need a finish but I used THIS STAIN on the outside frame to compliment the colors in the barn wood!
To attach the boxes to the wall, attached a 1×2 ( cut to the same size as the 1×4 on the outside frame) and attached the 1×2 to the wall with 2 1/2″ wood screws , through the studs behind the wall. Then, I set the window box over the 1×2 cleat and attached it to the cleat with 1 1/2″ wood screws from the top of the window box and into the cleat on the wall.
That was it! A super simple and inexpensive project that can take your windows from boring to fancy in just an afternoon!
