This step by step woodworking project is about how to build a 16×16 pavilion – free diy plans. I have designed this basic pavilion so you can create a covered area in the backyard, that is ideal for serving dinner or for hanging out with friends. This is a simple design so don’t expect intricate components. Follow the building codes and hire a professional contractor if you don’t have the right skills to undertake the project on your own.
A 16×16 wooden shelter for your backyard is a construction that can be built by any woodworking amateur in a few weeks, but there are many techniques you have to master before undertaking the project. However, building a gazebo, a pergola or even a backyard kitchen with an attached roof could be projects that are more suitable for your needs. It’s you job to decide what design does best for you.
We recommend you to invest in the best materials you could afford. Therefore, you should buy weather-resistant lumber, such as pressure-treated lumber, pine or cedar. Always take accurate measurements before adjusting the size of the components at the proper size. Drill pilot holes trough the components before inserting the wood screws, to prevent the wood from splitting.

How to build a 16×16 pavilion
The first step of the project is to layout the pavilion. Therefore, select the location for the pavilion and level the surface with attention. Make sure you remove the vegetation layer and even out the surface. Use batter boards and string to layout the location of the legs. Apply the 3-4-5 rule to each corners, so you make sure they are square. Measure the diagonals and make adjustments so they are equal.
After marking the location of the posts, you need to dig 2-3′ deep holes in the ground, using a post hole digger. Install tube forms and fit the posts into place, making sure they are perfectly plumb. Secure the 4×4 posts with braces before filling the forms with concrete.
Use 6×6 lumber for the top plates. As you can easily see in the diagram, you need to make notches to both ends of the beams, using a circular saw. Make the middle notch to the front and back plates using a saw and a chisel. Smooth the recesses with sandpaper.
Fit the plates to the top of the pavilion and align the edges flush. Make sure the corners are square and drill pilot holes before locking everything together with 8″ screws.
Build corner braces for the pavilion from 6×6 lumber. Make 45 degree cuts to both ends of the braces and then lock them into place tightly with 4 1/2″ screws. Plumb the posts and check if the plates are perfectly horizontal.
