Do you have a concrete patio that could use some upgrades?

Are you looking for a stylish and unique place to sit outside when you want to use your patio?

Have you considered adding a pergola over your patio slab to make it more unique and aesthetically appealing?

If so, you’re in the right place! In this article, we’ll teach you everything you need to know about how to build a pergola on concrete patio slabs. You’ll find out about the types of materials you need and the ways in which you can modify these plans to create something unique, too.

Adding a pergola onto a concrete patio can be a great addition to your backyard. Here are some of our favorite reasons why:

How To Build A Pergola
  • A pergola can improve the appearance of your yard. This is a classy structure that has a look of refinement and finesse about it.
  • You can grow several types of plants and flowers underneath a pergola, and you may even be able to grow some that climb or hang from the top of the pergola for added beauty and appeal.
  • A pergola can give you an elegant place to decorate and entertain when you’re looking to have friends over. This is a much more unique type of space than a porch or patio, and if you live in a place with a mild climate, it may be perfect for your needs.

Of course, no matter what inspires you, you’re sure to love the pergola you can build by following the directions below.


how to build a pergola
  • 3 pieces of 2x8 lumber
  • 14 pieces of beam lumber (slightly longer than the length of your pergola)
  • Two pieces of lumber to form your posts
  • Note: The length of this lumber will change depending on the height you’re looking to get out of your pergola.
  • Jigsaw
  • Power drill
  • Masonry bit
  • Countersink bit
  • Stainless steel screws
  • Lag screws
  • Post anchors
  • Fascia board
  • Ratchet
  • Ledger board
  • Four galvanized steel post brackets
  • Hammer and heavy-gauge nails
  • Spike
  • Clamps
  • Handsaw


  • 1
    First, decide how tall you want your pergola to be. From the corners of the patio pad that are adjacent to your home, measure this height and draw two perpendicular lines to mark where you’re going to place the height of the pergola.
  • 2
    Gather your three 2x8 pieces of lumber and notch them using a jigsaw so that they can hold and support four beams.
  • 3
    Level the ledger board you’re going to be using for the side of the pergola that is supported by the house. Pre-drill holes for your lag screws into the ledger board and fascia board both.
  • 4
    Tighten the lag screws into the ledger board and fascia board using your ratchet.
  • 5
    Mark the center of your four posts on the concrete by hammering a spike into the concrete to make a noticeable indentation.
  • 6
    Use your drill with a masonry bit to make a hole at each of these marks.
  • 7
    Place an anchor for the posts into each of these holes through the concrete and tighten.
  • 8
    Install post supports by hammering the posts to the brackets using your hammer and heavy-duty nails.
  • 9
    Clamp temporary braces made of extra lumber to your posts to hold them upright and in place until you’re finished building.
  • 10
    Pre-drill countersink holes and then attach the notched end beams to the posts you have installed using your screws.
  • 11
    Notch six pieces of lumber for your beams so that they can interlock with the notches you cut on the previous pieces of lumber.
  • 12
    Interlock the layers and trim with a handsaw, or leave overhanging for a more rustic look.
  • 13
    If you prefer, you can always trim the edges of the beams so that they’re more rounded for a decorative finish. This is entirely up to you and only alters the aesthetics of the pergola, however.


pergola design ideas

Remember that you aren’t limited to the pergola design listed above. There are a lot of different types of pergolas out there, and as long as you’re constructing something with four posts (or two posts and support from the side of your home for the other side of the structure), and something that has a slat-style roof, you’re probably building a pergola. When it comes down to it, the most important thing to remember is what a pergola is and how you can secure it firmly to your existing concrete patio without worrying about it getting knocked over by weather situations.

You can always customized the pergola plans listed above to meet your specific needs. Here are some helpful tips to keep in mind if you’re planning to customize your pergola plans:

  • Remember to be creative with the decorations and finishing touches you give to your pergola. If you want to carve something decorative into the ends of the beams or you want to paint or finish the pergola’s wood differently, there’s no reason why you can’t. This is perhaps the easiest way to give your pergola a unique flair from the directions listed above without going too over-the-top or needing any other extra skills you may not have for this type of project.
  • Don’t forget to adjust your measurements as needed. If you have a taller house, such as a two-story home, you may be able to get away with much taller posts than you would for a shorter home. You might also want to build a longer or wider pergola than the one listed above. This pattern is very easy to change around as needed, but if you make your pergola much wider or longer, make sure you’re adding extra support beams going in both directions to ensure your structure can stand up securely. You may also want to add extra posts depending on how long it is.
  • Get creative about the type of notching and slat layering you try, too! You can always change the pattern entirely or give yourself different thicknesses in the type of beams you use for the roof of your pergola. Just remember that, if you choose to cover or enclose the pergola, it will become a porch or a lanai instead, and it will not have the same aesthetic look you may be going for.

There’s a lot to remember when you’re building a pergola, but with the right plan in mind, you’ll have a great outdoor space in no time.
