Step-by step plans to make an arbor-like cedar structure, with 3D animation and master-level blueprints (How to Build a Pergola Right in Your Backyard). Here’s a structure that won’t provide shelter from wind or rain, and is only marginally better when it comes to the midday sun. So, why build it? Because in the absence of walls and a roof, it defines an outdoor space without constraining it. It’s a unique architectural blend that places you both inside and out at the same time. The structure is called a pergola, and it’s just the thing to bring backyard landscaping to life. Pergolas were common features of Italian Renaissance gardens, often covering walkways or serving as grape arbors. Today, the same design can be used to define a passageway or frame a focal point in your yard. Add a climbing plant such as wisteria or, yes, grapevines, and your pergola will provide color and shade as well.
