This step by step diy project is about 12×12 pergola plans. I have designed this pergola with a 12×12 base and a 14×14 roof, so you can create a nice shaded area in your backyard. This square pergola is extremely easy to build, while it has that exquisite look most of us strive for. Take a look over the rest of my woodworking plans, if you want to get more building inspiration.
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.

How to build a 12×12 pergola plans
The first step of the pergola project is to layout the 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.
There are a few ways to secure the 6×6 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 12-13″ 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.
Use 2×8 lumber for the support beams. Make decorative cuts to both ends of the beams. You can use a large circular item so you can draw the curved lines. Get the job done with a jigsaw and then smooth the edges for a neat result.
Fit the support beams to the top of the posts. Use a spirit level to plumb the support beams and then clamp the beams into place tightly. Drill pilot holes through the beams and through the posts. Insert the 9″ carriage bolts and then tighten the nuts.
Use 2×6 lumber for the shade elements. Make the curved decorative cuts to both ends of the beams. Mark the cut lines and then get the job done with a saw. In addition, you need to make a few 2″ deep notches, so you can fit the shade elements to the support beams.
Mark the cut lines on the beams and then use a circular saw to make parallel cuts. Use a chisel to remove the excess and then smooth the recess with sandpaper.
Fit the shade elements to the support beams. Place the shade elements equally spaced and then lock them into place with rafter ties. Alternatively, you could drill pilot holes through the shade elements (above the notches) and insert 5 1/2″ screws so you can lock them into place tightly.
Fitting the top slatsFit the 1×2 slats to the top of the pergola. Place these slats equally spaced for a professional result. Center the slats to the rafters and then drill pilot holes, before inserting the 1 5/8″ screws.

You can also fit braces, if you live in a windy area. Apply a few coats of paint or stain over the components, to enhance the look of the pergola and to protect the components from decay.
