Please scroll down the page to find chart showing specifications for Geodesic Dome Home, square footage by floor,  first floor ceiling height if a second floor is installed above first floor, dome interior height, etc.  

American Ingenuity manufacturers eight different dome size building kits.  Domes are measured by diameter in feet.  The 22′ dome can have a first floor only while the 27′, 30′, 34′, 36′, 40′, 45′ and 48′ domes can have a second floor framed with wood 2×10 joists.  If a cupola is installed on top of a 40′, 45′ or 48′ dome there is enough interior height to install a small loft area under the cupola.

The floor plan selected determines how much of the second floor is installed. Where a second floor is not installed there will be high vaulted ceilings over first floor areas.   It is typical that one half to two thirds of the second floor is installed.  However any of the domes can be  built with no second floors.   Below are pictures of some of the dome sizes.

American Ingenuity’s dome kit includes four foot tall riser panels before the triangle geometry.  Ceiling Heights in first floor rooms that have second floor installed above them is either 7′ 6″ or 8′.   22′, 27′, 30′, 34′ & 36′  kits – 7’6″.   40′, 45′ & 48′ – 8′.

How to have 8’6″ or ten feet first floor ceiling heights in rooms with a second floor installed above them:  In 22′ & 27′ domes custom order five foot tall risers instead of the standard four foot tall risers which results in eight foot six inch ceiling height.  In 30′, 34′, 36′, 40′, 45′ & 48′ domes order taller entryway panels and custom two foot tall risers to be installed above the 4′ risers to result in ten foot first floor ceiling heights. In areas that have no second floor installed above them, there are high vaulted ceilings.

DOME GEOMETRY: Frequency is the number of intersections from the center of one pentagon grouping to the next pentagon grouping.

  • Ai’s 22’ and 27′ domes are 2-frequency, 1/2 spheres on a 4′ vertical riser.  Instead of the standard four foot riser panel, a five foot riser panel with taller entryway panels can be ordered.
  • Ai’s 30’, 34’, 36′, 40’, 45’, and 48′ domes are 3-frequency, 3/8 spheres on a 4′ vertical riser.  Instead of the standard four foot riser panel, additional two foot risers & taller entryway panels can be ordered.

American Ingenuity’s 30′ through 48′ in diameter domes are approximately a one half sphere with a four foot tall riser wall.

5/8 Domes:

  • Ai. finds it more practical to use a vertical 4′ riser wall on all of its domes instead of designing its domes with the 5/8 geometry.
  • Ai’s 30′ dome turns out to be almost the same height as a 5/8 dome.
  • Also the 4′ riser wall makes for a better shaped entryway and allows the dome to link with all of our other size domes.
