24×24 Lean to Pavilion – Free DIY Plans

by Ovidiu


This step by step diy project is about 24×24 pavilion with lean to roof plans. This pavilion has a ground area of 24 ft x 24 ft, but the roof is wider so it will protect more space, as it has overhangs on all sides. This pavilion features a post frame structure made from 6x6s and 6x8s. The pavilion features a lean to roof with generous overhangs on all sides. The base of the pavilion is 24’x24′. Total height of the pavilion is 15′ 4″. The roof pitch is 3:12. Take a look over the rest of my woodworking plans, if you want to get more building inspiration. Premium Plans for this project available in the SHOP.

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.

24×24 Lean to Pavilion Plans



First, layout the posts for the 24×24 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 16″ in diameter. Fit the tubes then the posts into the ground and plumb them with a spirit level. Fill the holes with concrete and insert the post anchors. Align the anchors one to another and let the concrete set for a few days.

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.



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 24″ overhangs to the front 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 6×8 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 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.



Fit the 6×6 supports to the back if the pavilion. Plumb the posts and lock them into place with 2 L brackets and 2 1/2″ structural screws. This pavilion has a 3:12 roof pitch, so make sure you adjust the size of the pavilion if you want to change the slope.



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 top plates. Use 2 1/2″ structural screws to lock the connectors into place.



Fit the 6×8 ridge beams to the top of the supports. Notice the 24″ overhangs on both sides of the pavilion. Use post to beam connectors and 2 1/2″ screws to secure the beams to the supports.



Fit the 6×6 lumber for the top ridge beam braces, Make 45 degree cuts to both ends of the braces and secure them to the frame of the pavilion, using 5 1/2″ screws. Drill pilot holes before inserting the screws, to prevent the wood from splitting.



Fit the braces to the middle ridge beam, as shown in the diagram. Drill pilot holes and insert 5 1/2″ screws to lock them into place. Plumb the supports with a spirit, before inserting the screws.



I recommend you to take a look over PART 2 of the  project, where I show you how to build the lean to roof for the outdoor pavilion.



This garden pavilion with a lean to roof is large enough to shelter an outdoor corner dedicated to relaxation and hanging out with friends and family. The roof structure is strong enough for winds and snow, but I recommend you to read the local codes and make modifications, if necessary. You should also take a look over my 24×24 pavilion with lean to roof, as it makes for a more stylish alternative to this plan. Premium Plans for this project available in the SHOP.
