A pergola can be an attractive addition to your backyard and is a great way to add dappled shade when there are no trees. Chris Lambton from Going Yard demonstrates the steps for building a pergola: 1) Digging and pouring the footings. 2) Anchoring the posts to the footings and adding the joists. 3) Attaching stringers to connect the sides of the pergola and add your own style. The only design rule for a pergola is that you like it.
