10×8 Gable Rectangular Gazebo – Free DIY Plans

This step by step woodworking project is about how to build a 10×8 rectangular pavilion – free diy plans. This is a beautiful shelter that you can build for your grill or brick bbq. This gazebo features a sturdy structure that you can build with materials available in almost any lumberyard. The roof has a 8:12 pitch and it features 2×6 rafters every 16″ on center. This structure is heavy duty, but please follow the building codes and hire a professional contractor if you don’t have the right skills to undertake the project on your own. See all the gazebo plans HERE.

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. See all my Premium Plans HERE.

Laying-out-the-posts—10×8-pavilion

The first step of the HowToSpecialist.com project is to layout the rectangular grill gazebo. Therefore, select the location for the outdoor 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.

Setting the posts

After marking the location of the posts, you need to dig 3-4′ deep holes in the ground and 12″ in diameter, using a post hole digger. Install tube forms and fill them with concrete. Secure the anchors.  For this project we will use post anchors, so you don’t need to set the posts into concrete.

After installing the posts you need to check the tops are aligned one with another. Use a laser level / water level to mark the horizontal line to the top of the posts. Use a circular saw to make the cuts if necessarily.

Top-plates

Use 6×6 lumber for the top plates. Make notches to the beams, using a circular saw. Set the saw depth at 2 3/4″. Make the notches to the plates using a saw and a chisel. 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.

Fitting-the-side-top-plates

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. Use 2 screws for each joint.

Fitting-the-cross-beams

Fit the crossbeams to the top of the pavilion. Drill pilot holes and insert 10″ screws, to assemble everything together tightly. Use a spirit level to make sure the plates are horizontal. Use a carpentry square to make sure the corners are right angled.

Fitting-the-braces-to-the-frame-of-the-pavilion

Use 6×6 lumber for the diagonal braces. Make 45 degree cuts at both ends of braces and then fit them to the frame of the gazebo, as shown in the diagram. Plumb the posts, drill pilot holes through the braces and insert 5 1/2″ screws into the posts and top plates.

Fitting the supports

Use 6×6 lumber for the ridge beam supports. Center the supports to the cross plates and secure them into place with 2 1/2″ structural screws and post to beam connectors. Plumb the posts with a spirit level before setting the supports into place.

Ridge-beam-for-pavilion

Use 6×6 lumber for the ridge beam. Notice the 16″ front and back overhangs. Place the ridge beam to the supports and make sure the corners are square. Use post to beam connectors and 2 1/2″ structural screws to secure the beam into place tightly.

Fitting-the-braces-to-the-ridge-beam

Use 6×6 lumber for the top ridge braces. Make 45 degree cuts at both ends of the braces and then secure them to the ridge beam. Drill pilot holes and insert 5 1/2″ screws to lock them into place.

Rafters—10×8-gable-pavilion

Use 2×6 lumber for the rafters of the HowToSpecialist.com pavilion. Make 33.5 degree cuts to one end of the rafters and then make the birdsmouth cuts, as shown in the diagram. The roof has a 8:12 pitch which corresponds to a 33.5 degree slope.

You are free to play with the angles and change the roof slope. Just remember that changing the angles will also change the height of the ridge beam supports. Mark the cut lines to the beams and get the job done with a circular saw. The birdsmouths cuts are needed so you can fit the rafters to the plates and ridge beam properly.

Fitting-the-rafters—gable-pavilion

Fit the rafters to the top of the pavilion. Use the info from the diagram to space the rafters every 16″ on center. The number you see in the plans represents the distance between the rafters. Use rafter ties and 1 1/2″ structural screws to lock the rafters into place tightly.

Fitting-the-purlins

Fit the 1×4 purlins to the top of the gazebo roof. Place the purlins every 24″ on center. Align the edges flush and insert 1 5/8″ screws to lock the purlins to the rafters.

Fit the 1×8 trims to the sides of the pavilion. Align the edges flush and insert 6d nails to lock them to the rafters.

Gable end trims

Use 1×8 lumber for the front and back roof trims. Make 33.5 degree cuts to one end of the trims. Attach the trims to the rafters and insert 2″ nails to lock them into place tightly.

Fitting-the-roof-sheets

Fit the metal roofing sheets to the top of the pavilion. Align the edges flush and insert 3/4″-1″ roofing screws to lock the panels to the purlins. In addition, fit drip edges to al sides of the roof, making sure you read the manufacturer’s instructions.

10×8-Gable-Pavilion-Plans

This is a relatively small pavilion, so if you have a big family or many friends, I recommend you to take a look over the rest of my designs, for example this 20×24 pavilion or this 12×16 pavilion.

I had a lot of fun designing this shelter and this is the one I would chose for my grill / pizza oven. I like the increased roof pitch and the gable roof with generous overhangs on all sides.

Last but not least, 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. Since you are here, you might as well take a look over over my screened gazebo plans.
