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.

Building a Backyard Pavilion Plans

Laying-out-the-posts-for-the-pavilion
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.

Anchoring the posts of the anchor
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.

Fitting the posts
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.

Side top rails
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.

Fitting the side top rails
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.

Front-and-back-top-rails
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.

Fitting the front and back top rails
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.

Fitting-the-ridge-beam
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.

Building the braces
Build the braces from 6×6 lumber. Cut both ends of the braces at 45 degrees.

Fitting the braces
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.

Building a picnic table
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.

Thank you for 16×16 plans. my wife and i are taking on this project and we are first time DIY’S. under the material list it references beam to post connectors and strong tie T to be used during this project. the directions aren’t explicit as to when and where to use them but am i to assume that we will use post and beam connectors on every post and beam connection/ what about the strong tie T?
thanks in advance
The T tie is to connect the beam to the ridge beam supports. Make the joint more sturdy.
Thanks for the quick response. So will we use the notch (Timber Frame)method along with the post and beam (brackets and connectors) method?
Is there a way to eliminate the center post on the open end of this structure? I am building this structure over an existing bar area and I do not want the post in the center. Can I do anything to upgrade the structure at the front in order to eliminate the post? Thank you.
