An arbor is an overhead system of beams, usually supported by posts, that provides shade and is often used to train climbing plants. Arbors can be built as independent yard structures, but they often are combined with a trellis—a lattice wall attached to the side of the arbor. The combined arbor-and-trellis is a traditional, attractive outdoor structure.

Build your arbor structure so it is freestanding—do not attach it directly to your house. A permanent structure that is attached to a house must meet more code requirements than freestanding structures, and there is more risk of structural failure. The arbor featured in this section is made with four-post construction, set on sturdy concrete footings. Because it is freestanding, the footings did not need to extend below the frost line. Very small garden arbors can be built with techniques and materials similar to those used for the project shown, but may not require post footings.
