Measure the outside footprint of the gazebo, where the widest part of the gazebo meets the ground. Then measure the dimensions of the 4-by-4-inch wooden runners that provide structural support on the bottom of the gazebo.
Decide if you'll incorporate landscaping around your gazebo, or just install the gazebo itself on the lawn. If you install landscaping (such as flowers and shrubs) around the gazebo, work from the outside footprint measurement taken. If not, use the dimensions of the 4-by-4-inch wooden runners that provide structural support on the bottom of the gazebo.
Dig the foundation hole to a depth of 5 inches, using the measurements taken (either with or without landscaping). The foundation should be flat and level. If the gazebo is not of a square design, make sure that the foundation represents the basic shape of the gazebo. Be sure it is in the direction you want it to face.
Install either plastic sheeting or a weed barrier to the bottom of the foundation hole. This will prevent weeds from growing up between the floorboards.
Lay a bed of gravel on the weed barrier and spread it out. The gravel should be approximately 3 inches deep. Place the gazebo on top of the foundation.
Things You Will Need
- Work gloves
- Plastic sheeting or weed barrier
- If landscaping will be installed around the gazebo, add an extra 24 inches to the overall dimensions used to dig the foundation (in the areas that will be planted). No gravel is needed in these areas, but the weed barrier should still be applied.
