What Defines a Traditional Pergola Design?
A traditional pergola is a freestanding or attached garden structure built on a beam-and-post frame: vertical load-bearing posts — typically four or more — carry horizontal beams, with cross rafters running perpendicular overhead to create a slatted, open canopy. That assembly is the defining characteristic of pergola traditional construction, unchanged in its essentials for centuries. Decorative details such as chamfered beam ends, notched rafter tails, and symmetrical proportions in the classical or colonial tradition distinguish this approach from modern pergola systems, which use flat aluminium extrusions, motorised louvre blades, and minimal visible hardware. Traditional designs express craftsmanship at every joint rather than mechanical function. If you are comparing options, confirm that any builder you speak with offers genuine timber beam-and-post construction rather than a rebranded aluminium kit.
