12×30 Gable Pavilion Plans

This step by step diy woodworking project is about a 12×30 outdoor pavilion plans. This is a large pavilion built on a sturdy 6×6 structure and with a gable roof. This roof has a 6:12 pitch and it is really easy to build with my free set of plans. This pavilion is sturdy, but I recommend you to take a look over the local building codes, so you can comply with the legal requirements. 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.

The first step of the project is to layout the posts for the 12×30 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. 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.

Locking the posts into place

Locking the posts into place

Dig 3′ deep holes into the ground with a post hole digger. Align the holes with attention and then fit form tubes. Fit the 14″ tube forms with attention and align them using string. Use a spirit level to plumb the post anchors. Fill the tube forms with concrete and let it dry out for a few days.

Attach the posts with temporarily braces and secure them to the anchors with screws. Plumb the posts and then use a water level or a laser level to make sure the top of the posts are at the same height.

Use 6×10 lumber for the top support beams. Mark the cut lines on the beams and then make the cut outs with a circular saw and a chisel. Smooth the surface with sandpaper.

Set the circular saw at 4 5/8″ and then make parallel cuts inside the marked areas. Clean the recess with a chisel and sandpaper. We will need 4 pieces of the 16′ long plates and 3 pieces of the 12′ long beams.

Fit the top rails to the sides of the pavilion. Notice the 12″ 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.

Fitting-the-cross-beams

Fit the cross plates to the pavilion. Align the edges flush and drill pilot holes. Insert the 8″ screws to lock the cross plates into place tightly.

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.

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. PREMIUM PLANS available in the Store, if you need more info on the project (cut plan, ads-free, pdf download).
