You'll also notice at this point, the stacking method helps prop up the studs while working if at the same or taller height. Also, their weathered look adds to the Tiki theme. Just ensure that the top of the beam is nearly equidistant from the top of each post. Align the edges flush and drill pilot holes. Generally, this will involve connecting beams between each of the posts using hardwood and a hammer and nails. It's recommended that you get help with this next step.

Plumb the column and center it to the flooring surface. The decision will largely depend on the type you wish to build. For a basic, small deck, you could probably get away with (read the article) using just three joists. Now the support blocks could be removed. You can buy these at most home centers or patio supply stores. You could buy pergolas in kit form, but they're quite easy to build from scratch using treated softwood. Next, place the posts into the column anchors. For extra stability, you should attach the remaining two foundation columns to the wall. Then, take the same number of additional boards, or joists, and place them at each interior corner.
Set and level another temporary block on the opposite side to support the beam. Drive the stainless-steel screws into the beams and supports using a square-ended bit. Mark these distances on the main beams, being sure to center everything on the length of the beam so that the overhang is the same on both ends. Make sure the footings form straight lines and that the rows of footings are parallel to one another. To mitigate this, the support offsets must be measured from a reference point and all measured and cut accordingly. Some board are cut above the required. Once they have confirmed there are no underground lines in your future pergola location, begin digging the post holes.
