Cupolas are a venerable addition to homes, sheds and other structures. Cupolas aid in air ventilation and also add charm. The use of cupolas has been popular for centuries, and we have designed and built ours with long-term use in mind. These Octagon shaped cupolas will work on any Octagon shaped roof. PLEASE NOTE: These can be used as a replacement cupola on existing gazebos. Please contact us for details.
