A freestanding wooden structure is probably the most common type of pergola. It is a simple construction of posts supporting beams and rafters. As with arches, many pergola kits are available today for the do-it-yourself market. Assembly of these is much simplified; members are pre-notched, edges are planed, and corner braces may even be glued into place for you. These instructions are for a kit with 8 feet (2.4 m) posts set 4 feet (1.2 m) apart left to right, and 22 inches (55 cm) deep.

To guarantee a long life for a wooden pergola, always use sawn lumber that has been pretreated to last, and avoid rustic pole constructions. Be sure to also space rafters close together to cast more shade. For a light and airy structure, make the spacings between the rafters wider. Achieve a traditional look by choosing beams with shaped ends; a contemporary style is accomplished with beams that have square ends.
