Stylish Window Planter Box
Give your home’s curb appeal a little boost with these easy-to-build window planter boxes and learn a few woodworking tricks along the way.
Outdoor projects need to be built like a tank to handle the weather extremes they face. The problem is many outdoor projects often end up looking like tanks, too. But not this window planter box. While this simple project has the charm of a picket fence, it offers some great lessons in building for the outdoors. Underneath its cottage-style appearance lies a sturdy framework that easily supports a heavy-duty plastic liner filled with potting soil and plants. The construction is designed to shed water like a duck’s back for maximum durability. All this is accomplished by combining strong but light cedar, durable joinery, and some classic details. With an easy weekend’s worth of effort, you’ll enjoy the rewards of its design (and the blooms) season after season.

Imperial Plans
The United States Customary System of Units (USCS or USC), more commonly referred to as the English or Imperial system, is the standard set of units for our plans. It uses inches and feet for measurement. This is the one you probably want if you are in the United States, and it is the one we have traditionally offered on this website.

Metric Plans
The International System of Units (SI), more commonly referred to as the metric system, is the alternative set of units that we have available for some of our plans. It uses millimeters, centimeters, and meters for measurement. This is the one you probably want if you are outside the United States. These plans are provided by our business partner, Australian Woodsmith, and are based on the original Woodsmith plan. However, dimensions and other elements of the plan may vary between the metric and standard versions. Be sure to double-check the plan before building.


Premium Plans
All of the information that you need to build our plans can be found in the standard plan. However, if you want even more granular detail to make your job easier, you should consider our premium plans. These come with additional shop diagrams that we drew when creating the prototypes. Shop drawings are not available for every plan.
