Modern Slat Window Planter

As we've worked to transform the front of our home, we decided we wanted to add a window box. After doing a fair amount of searching, we realized there wasn't anything out there that fit our style. So, we designed and created this modern slat planter that extends all the way to the ground and fits well with the other updates we've done. It doesn't cost much and can easily be completed in a few hours.

Build Frame


I started by building the frame for the planter. I used pressure treated 2x4s and made the box the width of our window and 6 inches deep.

Attach to House


After building the square box, I cut 4 pieces of 2x4 to run from the frame box all the way to the ground. Before cutting the pieces, I dug out the loose dirt beneath the box and tamped down the ground. I then measured and cut the four side boards and added another 2x4 to connect the supports on the bottom. I used lag bolts to connect the top of the box to our house, right below the window.

Build Box Sides


My next step was to complete the planter area of the box that will eventually hold the dirt. I added a second row of 2x4s on each of the four sides at the top of the box, leaving a small gap for drainage.

Build Box Bottom


Then, I put two 2x4s side by side underneath those top two rows to make the bottom of the box - once again leaving small gaps between the boards for drainage.

Add Slats


Next, I added 1x4 cedar tone boards around the outside of the box to give it the slat look. I used pencils for spacers between the boards and mitered the front corners.

Add Landscape Fabric


I added two layers of landscape fabric to the inside of the box to hold the dirt.

Add Plants and Enjoy!


We're pretty happy with how the planter turned out.

It gives us the modern look we wanted.

    I love this idea and modern curb appeal you added. But……. Not to be negative. Can you tell me what you are doing to address possible long term issues? Ants/Termites and water? Really need to know before trying these ideas. Thank you

    What keeps it from tipping forward?

    I like where you are going with your unique design. Have you considered painting the two porch support posts black? They would match the base and stair railing - and "disappear" into the background.

    I love the idea of the Planter box BUT I live an area similar to the desert So very hot and dry in summer a d part of fall. So this creates conditions for spiders Black widows, brown spiders Daddy long legs, scorpions praying mantis and other insects. I need some ideas on what to plant to kind of deter these from being attracted to plants by the house. Dirt seems attract every bug imaginable plus earwigs. The ground is very hard and has lots of rocks in it anything more than 1/2 an inch going into the ground is nearly impossible but grass grows really well. I live in a manufactured home.. Any suggestions
