Yes, but carefully consider your options. In a Monolithic Dome a second floor will probably not save any money. A series of low-profile domes connected together and using only one floor can have the same floor area at a similar cost. A second floor may be appropriate because of the cost of land or the purpose of the building, or you may simply prefer a multi-story building.
Multiple stories can be “hung” directly from the dome, supported by interior walls, or a combination of both. “For more information on second floors click here.”/stories/second-floor
