This step by step diy woodworking project is about a 17×17 lean to pavilion plans. This is a large outdoor pavilion with a gable roof, ideal for outdoor parties and hanging out with the family. This makes for the perfect addition next to the property line. With some modifications, you can even attach the structure to an already existing building. 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. 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. See all my Premium Plans HERE.

It’s that easy to build a gable pavilion!
How to build a 17×17 pavilion – laying out
Laying-out-the-posts—17×17
First, layout the posts for the large 17×17 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
Dig 3 ft holes into the ground, making sure they have about 12″ in diameter. Fit the tubes then the posts into the ground and plumb them with a spirit level. Use temporarily braces to make sure the posts are locked into placed while filling the holes with concrete. Let the concrete dry out for several days. 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 large pavilion
Top-plates
Use 6×8 lumber for the rails. 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. Use 6×8 lumber for the other rails. 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.
Read the local codes and use 6×10 lumber for the top plates, if required (heavy winds / snow).
Attaching-the-top-side-plates
Fit the top rails to the sides of the pavilion. Notice the 18″ overhangs to the sides of the pavilion, for the front top plate. 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.
Attaching-the-crossbeams
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.
Braces-for-17×17-pavilion
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 2 screws for each joint.
Building the roof of the pavilion
Attaching-the-ridge-beam-supports
Fit the 6×6 supports to the top of pavilion. Plumb the supports with a spirit level. Secure the back supports with 2 L brackets each and 2 1/2″ structural screws.
Use post to beam connectors and 2 1/2″ structural screws to secure the middle supports to the frame of the pavilion.
Fitting-the-ridge-beams
Fit the 6×8 ridge beam to the supports with post to beam connectors. Make sure the corners are square. Use 2 1/2″ structural screws to lock the connectors into place.
Read the local codes and use 6×10 lumber for the top plates, if required (heavy winds / snow).
Top-ridge-braces
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.
Middle-ridge-beam-braces
Fit the braces to the middle ridge beam, as well.

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.
