10×12 Attached Pergola Plans – PDF Download

This step by step diy project is about 10×12 attached pergola plans. Therefore, a simple patio cover with a 10 ft x 12 ft base can be built with basic tools and common materials. This patio is ideal for an outdoor furniture set and maybe a TV. Take a look over the rest of my woodworking plans, if you want to get more building inspiration.

All my woodworking plans come with 3D diagrams and step by step instructions. In addition, the plans include full Cut and Shopping lists. Remember that you need to read the local codes before starting the project. It is your responsibility to make adjustments and suit the legal requirements.

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 one weekend. See all my Premium Plans HERE.

Step 1: Laying out the posts for the pergola

Laying-out-the-10×12-pergola

The first step of the pergola project is to layout the 4×4 posts. Use batter boards and string to layout the location of the posts. Apply the 3-4-5 rule to every corner and then measure the diagonals to make sure they are perfectly equal.

You need to make adjustments until you get the desired result. As you can see in the image, this pergola has a 10 ft x 12 ft base, outside post to outside post.

Anchoring the posts of the anchor

There are a few ways to secure the 4×4 wooden posts into place. You can set the posts in concrete or you can use adjustable anchors and pour footings. Dig the holes 3′ deep (or under the front line) and about 16″ in diameter. Compact a layer of gravel to the bottom of the holes and then fit the tube forms. Fit the posts, align them and plumb them with a spirit level. Fill the forms with concrete, while the posts are locked into place with temporarily braces. If you use anchors, you need to align and set them into concrete. Fit the posts after the concrete dries, using lag screw.

Smart tip: Read the local building codes, so you dig the holes at the appropriate depth. For this project, I will assume you will use post anchors, so if you set the posts into concrete, make sure you add 3′ to the posts size.

Installing the posts

Check if the posts are level and user a circular saw to make corrections. Notice the temporarily braces that hold the posts plumb. You need to keep the braces in place until you add the rafters to the pergola.

To determine the height of the posts, you need to secure the ledger to the house structure. The ledger will determine the height of the posts, because the first priority is to lock the ledger board to the rim joist of the house (see step 3).

Step 2: Fitting the support beam

Top-beam

Considering the 12 ft span between the posts, we need to use a 4×8 beam for the pergola. Set the beam to the top of the posts and make sure it has 12″ side overhangs. Use T ties and 2 1/2″ structural screws to lock the beam into place tightly. Ideally, attach the T ties on both sides of the joints.

Use a speed square to make sure the corners are right-angled. Use a spirit level to plumb the posts and to check if the beam is perfectly level.

Fitting-the-braces—10×12-patio-cover

Use 4×4 lumber for the braces. Make 45 degree cuts at both ends of the braces. Fit the braces to the frame of the pergola. Drill pilot holes through the braces and insert 5 1/2″ screws to lock them into place tightly. Use at least 2 screws for each joint.

Step 3: Fitting the ledger board

Ledger-board-height

We will use 2×8 lumber for the ledger. Secure the ledger to the house using the appropriate methods described by the local codes. Usually, it is done with lag screws that go directly into the rim joist or house joists. Use a spirit level to make sure the beam is horizontal.

Step 4: Fitting the pergola rafters

Rafters-for-attached-pergola

Decorative-ends-for-rafters

Next, we need to build the rafters for the pergola. 2×8 lumber is the best choice for this project, because it will reinforce the structure and add to the design. Use a jigsaw to make the decorative cuts to one end of the rafters. Mark the cut lines to the rafters and then get the job done with a jigsaw. Smooth the edges flush with sandpaper.

Spacing-the-rafters

Next, fit the rafters to the top of the support beams, every 24″ on center. Use rafter hangers and 1 1/2″ structural screws to lock the rafters to the ledger. In addition, use rafter ties and 1 1/2″ structural screws to lock the rafters to the support beams.

Step 5: Fitting the top slats

Fitting-the-top-slats

Furthermore, you need to take care of the finishing touches. Therefore, fit the 2×2 top slats to the pergola roof and lock it into place with 2 1/2″ screws. Drill pilot holes through the slats before inserting the screws, to prevent the wood from splitting.

The distance between the top slats determines the shade you get under the pergola. Therefore, the more slats you add the more shade you will have on the patio. Oppositely, if you want more sun on the patio, then you need to leave more space between the boards.

Step 6: Finishing touches

Last but not least, fill the holes with wood putty and then smooth the surface with 120-220 grit sandpaper. Apply a few coats of paint or stain over the components, to enhance the look of the patio pergola and to protect the components from decay.

This is a super easy to build a attached pergola with a simple but distinctive look. The base of the pergola is 10 ft x 12 ft, while the roof is 11 ft x 16 ft.
