12×16 Lean to Pavilion – Free DIY Plans

 

This step by step woodworking project is about how to build a 12×16 lean to pavilion – free diy plans. I had been working on this pavilion design for a long time making a lot of fine tuning till I’ve got this perfect shape and structure. The pavilion features a sturdy 6×6 structure with a lean to roof. The whole structure of the pavilion is interesting, so if you want an unique construction in your garden, these are the plans to go to. You will spend hours just watching the intricate structure of the roof unveiling its beauty upon the garden.

We recommend you to invest in the best materials you could afford. Therefore, you should buy weather-resistant lumber, such as pressure-treated lumber, cedar or redwood. If you use regular pine, I recommend you to apply the appropriate products to enhance its durability. Always take accurate measurements before adjusting the size of the components at the proper size. Drill pilot holes trough the components before inserting the wood screws, to prevent the wood from splitting. Please read the Local Building Codes so you determine the right depth of the footings and the pitch for the roof. In addition, they will provide useful information on the joints and other structural / technical aspects. See all my Premium Plans HERE ^[1].

How to build a 12×12 pavilion

The first step of the project is to layout the rectangular pavilion. Therefore, select the location for the pavilion and level the surface with attention. Make sure you remove the vegetation layer and even out the surface. Use batter boards and string to layout the location of the legs. Apply the 3-4-5 rule to each corners, so you make sure they are square. Measure the diagonals and make adjustments so they are equal. The local codes will also highlight some guidelines, so you can place the pavilion at the right distance from the fence and other building on the property.

After marking the location of the posts, you need to dig 3-4′ deep holes in the ground, using a post hole digger. Install tube forms and fit the posts into place, making sure they are perfectly plumb. Secure the 6×6 posts with braces before filling the forms with concrete. For this project we will use post anchors, so you don’t need to set the posts into concrete.

Smart Tip: Alternatively, you could use posts anchors. You need to secure the metal anchors into concrete, as to lock the wooden posts into place properly. Align everything with attention and with great care.

Use 6×6 lumber for the top plates. Make notches to the beams, using a circular saw. Make parallel cuts and then remove the excess with a hammer and a chisel. Smooth the recesses with sandpaper. These cut outs will help you create half lap joints, which makes for a strong and durable way of bonding wood together.

Fit the plates to the sides of the pavilion. Center the plates to the posts, making sure you have 16″ overhangs on both sides. Drill pilot holes and insert 8″ screws to lock them into place. Plumb the posts with a spirit level and check if the top plate is perfectly horizontal. Make sure the corners are square.

Fit the rest of the plates to the top of the pavilion. Drill pilot holes and insert 8″ screws, to assemble everything together tightly. Make sure the corners are square.

Use 6×6 lumber for the braces. Make 45 degree cuts to both ends of the braces.

Lock the braces into place tightly with 5″ screws. Plumb the posts and check if the plates are perfectly horizontal. Drill pilot holes before inserting the screws to prevent the wood from splitting.

Use 6×6 lumber for the ridge beam and for the supports. Center the supports to the top of the plates and lock them into place with strong tie connectors (L and T for the exterior). Fit the ridge beam to the top of the posts with post to beam connectors.

Cut the braces from 6×6 lumber, making 45 degree cuts at both ends. Drill pilot holes and insert 5″ screws to lock the braces into place tightly.

Fit the middle ridge beam to the top of the plates. Use post to beam connectors to secure the posts into place, as well as to fit the ridge beam.

This pavilion is built on a sturdy 6×6 structure and it features a roof with a 5:12 pitch. You can adjust the slope of the roof to suit your needs.

This pavilion makes for the perfect addition to a small backyard because it will save you space, since you can place it near the property line or to an already existing building. In addition, the pavilion is sturdy and it last for many decades. Last but not least, you can build this pavilion in a week with the help of another person, and thus, save tons of money as compared to buying one. If you want to build a pavilion with railings ^[3], I’ve got you covered with step by step plans.

You need to take care of the finishing touches. Therefore, fill the holes with wood putty and then smooth the surface with sandpaper. Apply a few coats of paint or stain over the components to enhance the look of the shed and to protect the components from decay. Please take a look over PART 2 ^[4] of the project, where I show you how to build the roof for the pavilion.

Smart Tip: Apply a few coats of stain or exterior paint to the components, in order to protect them from decay and water damage. Make sure you choose quality components that suit your needs and tastes.
