An easy DIY, I'm sharing all the details on how we built the pine flower boxes for the front of our home to add instant charm and curb appeal.
This spring, we added handmade pine flower boxes to the front of our home — and I can’t believe the difference they’ve made. There’s something so classic and welcoming about window boxes overflowing with flowers. They instantly softened the front of our house and brought that cottage garden feeling I’m always chasing.
These boxes were a simple weekend project that added charm and curb appeal without a huge cost. If you’ve been thinking of adding flower boxes to your home, here’s how we built ours, the materials we used, and a few tips for planting and upkeep.
Materials We Used:
-
Pine boards (we used 1x6s for the sides and bottom, and chair rail trim)
-
Wood screws + wood glue
-
Exterior primer + paint
-
Heavy-duty plastic liner (optional, for protecting the wood inside)
-
Drill + saw
-
Wall anchors + screws for mounting
-
Outdoor-rated mounting brackets or a board thats been ounted into studs or brick that runs beneath the window
📍 Note: Pine is an affordable and easy-to-work-with wood. We primed and painted ours to help protect them from weather and extend their life.
Dimensions:
We made each box to match the width of the windows they’re mounted beneath — roughly 3.5 feet wide, 8 inches high, and 7 inches deep. You can scale the size based on your window width and how much you want the boxes to overhang.
Step-by-Step Build:
1. Measure + Cut Boards
We measured our windows and cut the pine boards accordingly — one for the base, two for the front and back, and two short sides. The trim pieces were mitered to add a nice finished edge. But you can also purchase chair rail trim to make the assembly faster.
2. Assemble the Box
We used wood glue and screws to assemble the five main pieces into a box, then attached the trim around the top for a classic look.
3. Prime + Paint
We used an exterior wood primer followed by two coats of weather-resistant white paint (a soft warm white that ties in with our window trim).
4. Add Liner + Drainage
We drilled a few small holes in the base for drainage and added a plastic liner to protect the inside of the box. If you skip the liner, make sure to use exterior-grade paint or wood sealant inside and out.
5. Mounting to the House
We screwed our boxes directly to the board the previous owners had for their boxes. You can use wall anchors and outdoor brackets to mount the boxes beneath each window. Make sure they’re level and secure, especially once filled with soil.
What We Planted:
We went with a soft, romantic palette of white bacopa, dusty pink calibrachoa, trailing ivy, and a few mini petunias. I love the way they spill over the edges and soften the shape of the house.
🌸 The goal: fullness, trailing movement, and layers of soft texture.
