Hey there, fellow craft enthusiasts! Robert Kline here, and today we’re diving into the world of DIY home improvement with a project that’s sure to add a touch of charm and vibrancy to your living space: a custom-built window box.
I recently embarked on this journey myself, wanting to spruce up the area around my pool. Before taking the plunge and outfitting the entire house, I decided to start with a single box as a test run. It allowed me to get a feel for the process and see how it looked against my house.
And let me tell you, the result was fantastic! So, I decided to document the entire process and share it with you lovely people. Let’s transform your windows together, one box at a time!
Gathering Your Tools and Materials
Before we roll up our sleeves, let’s make sure we have everything we need. I opted for PVC to avoid any pesky wood rot issues. Here’s a breakdown:
Materials:
- (1) 1x8x10′ smooth PVC board
- (1) 1x3x8′ smooth PVC board
- (1) 1x2x8′ smooth PVC board
- (1) smooth PVC cove molding
- PVC cement
- Caulk
- 1 1/4″ finish nails
- 1 1/2″ Tapcon screws (for brick walls)
- 1 1/2″ wood screws (for siding)
Tools:
- Miter saw
- Table saw
- Tape measure
- Finish nailer
Building Your Window Box: A Step-by-Step Guide
Step 1: Measure Your Window
Measure the width of the window where your box will be installed. My window was 32 inches wide, so I made my box the same width.
Step 2: Make the Cuts
Here’s how I cut my PVC, but adjust the lengths to fit your window:
- (2) 1×8 at 32 inches (front and back)
- (1) 1×8 ripped to 6 1/2″ at 32 inches (bottom)
- (2) 1×8 at 8 inches (sides)
- (1) 1×2 at 33 1/2″ (front trim piece) – mitered ends
- (2) 1×2 at 8 1/2″ (side trim pieces) – one mitered end on each
- (1) 1×2 at 30 1/2″ (back trim piece)
- (2) 1×3 at 30 1/2″ (cleat) – ripped lengthwise at a 45-degree angle on the table saw
Step 3: Assemble the Box
- Apply PVC cement to the long edge of the ripped 1×8 board (the bottom piece).
- Use the finish nailer to attach it to one of the 32″ long 1×8 boards, setting it back 3/4″ from the edge to create a lip for the front piece.
- Apply PVC cement to the ends of the bottom piece and attach the 8″ side pieces using the finish nailer.
- Apply PVC cement to the front edges of the side pieces and attach the remaining 32″ 1×8 board to create the front.
Step 4: Add the Trim
- Apply PVC cement to the top edges of the box.
- Attach the 1×2 trim pieces using the finish nailer.
- Add PVC cement to the back of the cove molding and install it below the 1×2 trim on the front piece.
Step 5: Attach the Cleat
- Apply PVC cement to the back of the cleat.
- Center the cleat and attach it to the back of the box using the finish nailer.
Step 6: Drill Drainage Holes
Using a 1/2″ drill bit, drill three evenly spaced holes in the bottom of the box for drainage.
Step 7: Paint Time!
I went with Sherwin Williams Iron Ore to contrast my house color, but you can choose whatever color complements your style.
Step 8: Install Your Window Box
- Using a level, mark a straight line on the wall below your window for the cleat.
- Drill three pilot holes through the cleat.
- Align the cleat with your marked line and mark the wall through the pilot holes.
- Using a hammer drill and masonry bit, drill pilot holes into the brick.
- Attach the cleat to the wall using Tapcon screws.
- Slide the window box onto the wall-mounted cleat.
Step 9: Add Your Favorite Plants
Now for the fun part! Choose plants and flowers that will thrive in the light conditions of your chosen location. I recommend adding potting mix to the bottom of the box and around the plants’ roots.
