This 1/30 scale cardstock model has its front face removed to display the interior of the dome. The full sized dome is composed of 90 full size basic panels weighing approximately 70 pounds each. The maximum dimension of each panel being 7 1/2'. The panels can be preinsulated to an approximate R-16 with an option to upgrade to an approximate R-40. The panel framing is constructed of approximately 375 2x4s at a cost of around $1200. The sheathing consists of approximately 115 sheets of 1/2" OSB at a cost of around $1100. The 1st floor area is around 1100 s.f. with a 2nd floor area of around 660 s.f.. If you have an insulated basement, this would give you a total of around 2900 s.f. at a basic dome framing and sheathing cost of less than $1.00/s.f.
The scale model can be downloaded in a gif format located within a zip file.
This quasi 4 frequency golden mean based dome can be built from only two panel patterns. It requires no kneewall nor does it require any stem wall supports.
To access WEB page giving a condensed fabrication process go to http://hometown.aol.com/gmdome/fabricate.html. This process is simpler and uses less expensive equipment to fabricate the basic dome panels than the original process.
The 38' dome design is still in the testing phase.
