20×30 Pavilion Plans
This step by step diy woodworking project is about a 20×30 outdoor pavilion plans. I had a request for a large pavilion with a simple design, so I’ve come up with this design. This small pavilion has a gable roof and it is super simple to build. Make sure you take a look over the local building codes, so you comply with the regulations. 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.

How to build a 20×30 pavilion
Laying out the posts
The first step of the project is to layout the posts for the 20×30 pavilion. Use batter boards and string to determine the location of the posts. Apply the 3-4-5 rule to every corner of the pavilion, so you make sure they are right angled. Moreover measure the diagonals and make sure they are equal. Determining the location for the pavilion is essential, as you have to comply with the local building codes. Make sure the surface is level and remove the vegetation layer.
Level the surface with attention. Remove the vegetation layer, as well. Dig 3′ deep holes into the ground with a post hole digger. Align the holes with attention and then fit form tubes. Fit the 6×6 posts with attention and align them using string. Use a spirit level to plumb the posts and then lock them into place with temporarily braces. Fill the tube forms with concrete and let it dry out for a few days.
Use 6×6 lumber for the top plates of the pavilion. As you can notice in the plans, you have to make notches to the beams, so you can join then them together. Mark the areas and then make parallel cuts with a circular saw set at a depth of 2 3/4″. Remove the excess material with chisel and smooth the recess with sandpaper.
Repeat the process for the front and back top plates of the pavilion. Make the notches and remove the excess.
Fitting the top beams
Fit the rails to the sides of the pavilion. Align the edges flush, making sure the corners are square, drill pilot holes and insert 5 1/2″ screws.
Continue the project by building the ridge beam. Make recesses to the beam, so you can fit it into place properly.
Fitting the top ridge
Fit the 6×6 supports to the front and back of the pavilion. Plumb the support with a spirit level and make sure the corners are square.
Front and back braces
Build the braces from 6×6 lumber. Cut both ends of the braces at 45 degrees and then fit them into place tightly. Leave no gaps between the components, drill pilot holes and insert 5 1/2″ screws.
Fitting the braces
Fit the 6×6 braces to secure the ridge beam.
Fitting the top ridge braces
Fit the 4×4 braces to the top ridge. Make sure the corners are square before fitting the braces into place.

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.
