10×12 Pavilion Plans

This step by step diy woodworking project is about a 10×12 outdoor pavilion plans. I had a request for a simple 10×12 pavilion, so I have come up with this design. 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. See all my Premium Plans HERE.

How to build a 10×12 pavilion



The first step of the project is to layout the posts for the 10×12 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 plates

Fitting the top plates

Fit the top rails to the sides, to the front and to the back of the pavilion. Align the edges flush, making sure the corners are square, drill pilot holes and insert 8″ screws.



Build the braces for the front and back of the pavilion from 6×6 lumber. Use a miter saw to make 45 degree cuts to both ends of the braces.

Fitting the braces

Fitting the braces

Fit the braces to the posts, after you plumb them vertically. Drill pilot holes and insert 5 1/2″ screws to secure the braces into place tightly.



Fit the 6×6 supports to the top of the plates. Plumb the supports with a spirit level and then attach the top ridge. Make sure the corners are square and then insert 8 1/2″ screws.

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.
