Pavilions - Our largest structures A Gazebo's big brother, Pavilions are open-air octagonal structures, 21 feet or larger - the largest we offer. Our pavilions use the same basic design as a gazebo, with larger rails and frets, thicker posts, more roof tiers. All the features and options of gazebos are available in pavilions as well, from roof to finish. The same materials provide longevity and beauty. Appropriate for a park, corporate center or other large venue, our pavilions add grandeur to any locale. And if you need even more, consider our Grand Pavilions - multiple units joined together with walkways. They'll be the centerpiece of your venue.
