This listing is for a 20 foot diameter geodesic dome aviary. The dome is 11 feet 8.6 inches high in the center and features 297 square feet of floor space. The doorway dimensions are 6 feet 10.4 inches (82.4 inches) x 3 feet 11 inches (47 inches). The approximate dome kit weight is 400 lbs.

The foundation ring plans provide step-by-step instruction to create and assemble a ring of wooden 4x4s. The customer supplied materials are available at most home improvement stores. This provides an excellent means to produce a flat and level surface for the dome as well as to prevent direct contact between the frame and the soil. The foundation ring will add 3.5" of extra height to the aviary.

Other sizes are available - contact us for more information.

As each order is custom, please allow two to three weeks manufacturing time.

The Geodesic Dome Advantage

Geodesic domes use 25% less materials to enclose a given space as compared to conventional rectangular designs.

The lightweight and relatively short length of each frame strut allows any dome kit to be divided up into bundles of manageable weight.

Geodesic domes gain great strength by distributing loading through all structural members. Their rounded shape naturally deflects wind and sheds snow accumulation.

Any geodesic dome kit can have many uses and may be easily converted into a structure that suits a different application (e.g., a storage building during the winter and pool cover during the summer).

Thanks for looking!

Love my Dome. Instructions were great, everything numbered and easy to follow. We did go a little overboard and added wood to the bottom. Great product.

I ordered SunriseDomes' geodesic sphere for my monument sculpture project in art college. Justin was so accommodating. He shipped it really quick. Assembly was very managable thanks to the included instructions and the struts being lettered, you just follow the pattern. Everyone was so impressed with my piece! And I got an A in my assessment for this project. I am so grateful and highly recommend!
