Window flower box planters add charm and character to your home. I have been dreaming about how to decorate my window planters for each holiday and season. However, before I get ahead of myself, I would like to share how to build window boxes quickly.
I knew I wanted to make my little studio so charming I would like to spend all my time out there. It had woodpiles, bags of Quickrete, empty flower pots, and tools on the porch and stacked up along the outside walls. It was an eyesore.
How to Build a Window Box
Mr. Kippi built me an Adirondak chair and an obelisk for my little secret garden next to my studio. I stood back and looked at the prototype obelisk and chair with the window and old rain gutters. At that moment, I knew the window needed some finishing touches to add beauty. I wanted everything to coordinate with other outdoor home improvement projects I have done, so the white window got natural wood shutters and a window box to add to the home’s curb appeal.

I searched for inserts for the window boxes. Those inserts would determine the size of the window boxes could be. I choose this window box insert since they had a drip tray. I found this cute window box made by my friend, Rachel, that I adore, so I wanted one too.
Supplies and Tools
- 1 x 6 x 8 pressure-treated lumber
- 5/4 deck board pressure-treated
- Nails 1.5″ galvanized (box assembly)
- Nails 3/4″ galvanized (trim installation)
- Glue Titebond
- Window box insert with a water reservoir
- Wood sealer
- Sandpaper (100)
- Screws 2.5″ cabinet screws with washers
- Chop saw
- Table saw
- Drill (3/8″ bit for drain holes and 1/8″ bit for pilot holes)
- Nail gun
- Watering can
- Solar light
The first thing you will need to do is measure your insert and write down the height, width, and length. Note: take the measurements just under the upper lip of the insert if yours has one. Cut your (1 x 6 x8) lumber to accommodate those measurements.
Installing Window Flower Boxes
Inserting the Flower Box Liner
The window flower boxes are on opposite sides of the studio, so they needed different plants since one was in the shade and the other one got a ton of sun (Florida sun). You can see how I choose the flower plantings HERE.
You can see the area behind the obelisk; it needs a trellis with a garden planter and lanterns. You can see how we built those gorgeous trellises HERE. Please join our newsletter, so you don’t miss a thing. I will be sharing how to make shutters, Adoranik chairs, and the obelisk with solar lights.
The new custom rain gutter looks so much better. I did not notice how awful the rain gutters looked until I installed the window box and shutters. I called and ordered the rain gutter and downspout over the phone and had them delivered. It was the right decision to replace them.
This window box adds beauty both indoor and outdoor since I can see the flowers from inside too.
I created a DIY side table from a fallen tree. We also made some super groovy live edge hairpin leg tables you are going to love. You can see them in this post. The vintage style pot with the transfers can make one, too, in this earlier post.
If you love flower boxes and window box planters, you will enjoy building some and installing them on your home too.
