The BubbleDome line was developed to provide maximum interior space with a minimum footprint. We have taken our standard Solar and GroDomes and added an additional band of poles and covering to the bottom, which creates more height. The walls actually come in a little at the bottom, like a bubble, so the diameter at the ground is about a foot less than the widest part of the dome. Note that the BubbleDomes have only one door. We have also removed one pole section to allow for a tall door so that you can walk in without bending. The BubbleDome has a unique and friendly look that you will be proud to use.
