Pergola designs come in a variety of shapes and sizes. Examples can include round and triangular configurations, herringbone design with columns, exotic arches, and much more. They can feature seating, planter boxes, and even swings. Pergolas add just the right touch of style and comfort, serving as a shady retreat on long sun-filled days. Typically constructed from pressure-treated wood or cedar, a pergola is a great option that provides shade on walkways, terraces, decks or pools in a very distinctive way. Extremely versatile, pergolas can be the ideal complement to a multi-level deck, a design treatment above a garage, over an outdoor kitchen or as a shady accent over an outdoor room.
