12×24 Gable Pavilion Plans – PDF Download

by Ovidiu


This step by step diy woodworking project is about a 12×24 gable pavilion plans. This is a large pavilion built on a sturdy 6×6 and 6×8 framing, with 6 posts and a 12 ft x 24 ft base. The roof for this pavilion has a pitch of 6:12 and features large opening on all sides. 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. Premium Plans for this project available Here. Check out the Shop, as well, for full list of Premium Plans.

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.

It’s that easy to make a 12×24 gazebo!


How to build a 12×24 shelter



First, layout the posts for the large 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. Make sure the diagonals 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.

Setting the posts in concrete

Setting the posts in concrete

Dig 3 ft holes into the ground, making sure they have about 14″ in diameter. Fit the tubes then fill them with concrete and set the anchors. Align the anchors one to another and let the concrete dry out for several days. Next, attach the 6×6 posts to the anchors and plumb them with a spirit level. Use temporarily braces to lock the posts into place till you assemble the whole frame of the pavilion. 

Read the local codes for more details on how to secure the posts. Use lag screws to secure the posts to the anchors. Before pouring the concrete you need to make sure the top of the posts are horizontal one to another. Use a laser to mark the level to the top of the posts and use a circular saw, if you need to make cuts.


Building the frame of the pavilion



Next, we will be building the top plates for the backyard pavilion. Therefore, this pavilion requires at least 6x8s, due to the large spans on the front and sides. As you can see in the diagram, you need to make 3 5/8″ notches to the beams, so you can lock them together tightly. Use a circular saw to make parallel cuts inside the marked areas and remove the excess with a chisel. Smooth the recesses with sandpaper.



Fit the top rails to the sides of the pavilion. Notice the 16″ overhangs to the front and back of the pavilion. Drill pilot holes through the plates and insert 8″ screws to lock them to the posts. Use 2 screws for each joint. Make sure the corners are square and plumb the posts vertically.



Next, fit the cross beams to the pavilion frame. Align the edges flush and drill pilot holes. Insert the 8″ screws to lock the cross plates into place tightly. Use 2 screws for each joint


Fitting the braces



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. 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. Insert at least 2 screws for each joint. 



Center the 6×6 supports to the top of pavilion. Plumb the supports with a spirit level. Use post to beam connectors to secure the supports to the frame of the pavilion. Insert 2 1/2″ structural screws to lock the supports. 



Fit the 6×8 beams to the top of the supports. Notice the 16″ overhangs to the front and back of the pavilion. Use post to beam connectors with 2 1/2″ structural screws to lock everything together tightly. Insert structural screws through the connector. Make sure the corners are square and align the edges flush.



Use 6×6 lumber for the braces. Make 45 degree cuts at both ends of the braces. Secure the braces into place with 5 1/2″ screws. Drill pilot holes before inserting the screws. Use at least 2 screws for each joint. These braces will really reinforce the structure and add extra-support to the ridge beams.

Check out PART 2 of the project to learn how to build the gable roof. You can see in this image the overall dimensions for the large gable pavilion. This is really useful because it can shelter a picnic table or even an outdoor entertainment area. Moreover, this makes for a nice carport.

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 the Shop, as well, for full list of Premium Plans. If you want to get this project will full CUT and SHOPPING lists and 1 single PDF file, please check the GET PDF PLANS button bellow!

Hello, I’ve followed every step for the 12 x 24 Pavillion which by the way was nicely described on how to construct. I just have one question. In one of the detailed pictures, you show a finished height at the top of the beam of 100-1/2 inches. If I am setting the 6×8 on top of the 96-inch post would that not make it 107-1/2 inches. Please clarify because my posts are currently all at 96 inches from grade and ready to accept the nice (and very expensive) 6×8 cedar beams. Thank you for any advice you may have.

That height is referring to the height of the roof at its lowest point. Doesn’t have anything to do with the top plates.
