This step by step diy woodworking project is about a 16×16 outdoor pavilion plans. This article features detailed instructions for building an outdoor picnic shelter using 6×6 lumber for the structure and 2×6 beams for the rafters. Check out PART 2 of the project to learn how to frame the roof for the pavilion. Take a look over the rest of our woodworking plans, if you want to get more building inspiration.
When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. If you have all the materials and tools required for the project, you could get the job done in about a day. See all my Premium Plans HERE.

Building a Backyard Pavilion Plans
The first step of the project is to layout the posts for the pavilion. Use batter boards and string to lay out everything in a professional manner. Apply the 3-4-5 rule to every corner, to make sure they are right-angled. In addition, measure the diagonals and make adjustments until they are perfectly equal.
There are several ways to lock the posts into place. Therefore, you could dig 2′ holes in the ground and set the posts into concrete, or you could use post anchors. Use tube forms so that the footing will be really strong.
If you want to set the posts in concrete, then you need to use temporarily braces. Plumb the posts with a spirit level. Read the local building codes for finding the right depth of the footings. It is essential to set the footing at the right depth to avoid them being heaved by the Winter freeze/thaw cycle.
Build the side top rails from 6×6 lumber. As you can easily notice in the diagram, you need to make notches to the ends of the beams. Use a circular saw to make 2 3/4″ deep cuts to the marked area. Make parallel cuts to the marked areas and clean the notches with a chisel. Smooth the surface with sandpaper.
Fit the rails to the sides of the outdoor pavilion. Make sure the posts are plumb and check if the corners are square. Drill pilot holes and insert 5-6″ screws to lock the components into place.
Build the top rails for the front and back of the pavilion. Make notches to the 6×6 beams, as shown in the diagram. Clean the recesses with a chisel and smooth the surface with sandpaper.
Fit the beams to the top of the pavilion. Drill pilot holes and insert 8″ screws so that you lock the rails to the posts.
Next, you need to fit the vertical supports to the top rails, as shown in the plans. Use a spirit level to plumb the supports. In addition, use corner brackets to create strong joints. Afterwards, attach the top beam to the supports. Make sure the corners are square, before locking the top ridge into place with screws.
Build the braces from 6×6 lumber. Cut both ends of the braces at 45 degrees.
Make sure the corners are square and then set the braces to the structure, as shown in the diagram. Drill pilot holes and insert 3 1/2″ screws into the posts and top rails.
Fill the holes with wood putty and let them dry out for a few hours. Smooth the surface with 100-220 grit sandpaper and remove the residues with a damp cloth.
Top Tip: Apply a few coats of paint or stain to the components, to enhance the look of the project. Check out PART 2 of the project so you learn how to build the roof for the pavilion.
