Window boxes are an easy way to increase your growing space and spruce up your house at the same time. If you don’t have outdoor space for a garden, window boxes can be the next best thing. They’re also great for sensitive plants that need to be kept above possible pests. Plus, there is nothing better than looking out your window and seeing plenty of newly-bloomed flowers.

However, window boxes can be a bit expensive. They may not fit your window or style either, which can create all sorts of issues. Instead of spending plenty of money on a window box that may not fit, consider learning how to build a window box of your very own.

In this article, we’ll take a look at plenty of plans that you can use to build your window box today. Many of these are relatively simple since window boxes don’t tend to be incredibly complicated.

This plan outlines how to make relatively simple window boxes. However, they are a bit more elegant than some of the other window boxes we’ve listed thus far. In general, we recommend these boxes to anyone who wants to spruce up the outside of their house with some simple window boxes.

They work great with flowers and green plants, though you can use them for some veggies and such as well.

If you’re tired of plain, ordinary window boxes, try constructing this customizable DIY window box today. It’s rated as intermediate because of the power tools involved but points out that you can save a lot of time by building multiple boxes at once. At first, though, we recommend making one so you’re familiar with how the job goes. After that, move on to making the rest of what you need for the whole house. Don’t forget to drill holes for drainage in the bottom of these planters, or else water can accumulate and cause root rot.

This detailed guide from the Home Depot walks you through exactly how to build sturdy, long-lasting window box planters. There are tons of clear photos attached at each step for visual reference to follow along while you work, but we really like that it offers tips on painting and trim too. Another valuable tip is to put your plants in plastic-based containers before putting them in these window boxes to help them last longer.

For a twist on boring planters, consider trying out one of these DIY self-watering window boxes. It’s a perfect project to spruce up a naked big window or can be downsized to work with smaller windows. The watering system is ingenious but takes some extra cost and work to implement. Once complete, however, it’s a nearly self-sufficient system that feeds and eliminates drain water runoff by itself.

Using recycled materials, power tools, and some math, you can turn scrap into a functional window box planter. Pallet wood is perfect for this project, in case you’re hoarding some around your house, but scrap wood works fine too. For the inside, you can help prevent rot by lining it with plastic or glass materials. Again, recycled materials work great for this. Paint is optional if you’re really strapped, or you can leave it plain if it’s purely for storing plants and not for show.

13. No-Mount Window Box by My Urban Garden Oasis

If you’d rather avoid drilling into your house to install window boxes, this no-mount window box is right up your alley. Rather than being mounted by screws, this box stands on tall legs and accomplishes the same job of holding your pots. If you’d like to fill it with dirt, you may add another board on the bottom, but that cuts down on the box’s main strength: portability. Unlike mounted window boxes that attach to the wall, you can move this one to any window you want to.

14. Dresser Drawer Window Box by Home Talk

For window boxes with a vintage flourish, upcycle your dresser drawer to make unique window box planters. Simply add two wood brackets and a regular box planter, then cut the front of a dresser drawer off. The guide is light on the step-by-step details, but it appears that you simply screw that facade into the wood brackets directly. As a cheap alternative, you can just screw the dresser drawer piece directly into your exterior walls and add some Styrofoam for bouquets or small plants.

Cedar is the best choice here if you’re just filling the boxes with dirt, and you could alter their dimensions if needed. For bonus points, you can add multiple branching tiers, fewer tiers, or other modifications to fit your desired aesthetic.
