This step by step diy woodworking project is about a 14×18 outdoor pavilion plans. This is a large pavilion built on a sturdy 6×6 and 6×8 structure and with a gable roof. This roof has a 8:12 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.

How to build a 14×18 gable pavilion
First, layout the posts for the 14×18 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.
Dig 3′ deep holes into the ground with a post hole digger. Align the holes with attention and then fit form tubes. Install the anchors and fill the tube forms with concrete and let it dry out for a few days. Afterwards, install the 6×6 posts and secure them into place with lag screws. Align the posts one with another and also check if the top of the posts are horizontal. Use a circular saw to make the cuts, if necessary.
Use 6×8 lumber for the top rails. Mark the cut lines on the beams and then make the cut outs with a circular saw and a chisel. Set the circular saw at 3 5/8″ and then make parallel cuts inside the marked areas. Clean the recess with a chisel and sandpaper.
Fit the top rails to the sides of the pavilion. Notice the 20″ 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.
Fit the cross plates to the pavilion. Align the edges flush and drill pilot holes. Insert the 10″ screws to lock the cross plates into place tightly.
Build the braces for the base 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 (2 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 set the supports.
Fit the 6×8 ridge beam to the top of the supports. Align the edges flush and make sure the overhangs are equal on both sides. Use post to beam connectors and 2 1/2″ screws to lock the components together tightly.
Fit the 6×6 braces to the ridge beam, as shown in the diagram. Make 45 degree cuts to both ends of the braces and then secure them into place with 5 1/2″ screws. Remember that you need to plumb the posts vertically, before inserting the screws.
Check out PART 2 of the project to learn how to build the gable roof for the pavilion. The roof has a 8:12 pitch, but you can adjust this so it suits your needs and local codes.
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. This pavilion can also be used as a
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).
