When you view the stock plans for each diameter dome (27', 30', 36', 40', 45' and 48'), you will soon realize that the square footage of each plan in each diameter dome varies.  This square footage varies because the size of the second floor changes due to how much of the first floor is left open to give high vaulted ceilings over the first floor rooms. Plus the 40' or larger domes can have a third floor loft if a cupola is installed.

Some plans show the second floors maxed out meaning that only 30% of the first floor is left open with high vaulted ceiilings.  Other plans show high vaulted ceilings over one half of the first floor.  Look for the dashed lines because they reveal how much of the second floor is installed. 

On the second floor of each plan we draw 5', 6' and 7' height lines around the perimeter of the second floor.  These height lines allow you to envision how close you can stand to dome shell walls.  You can take the to-scale ruler and measure between the height lines to check out the space.  In a typical house there is an attic that you generally do not walk in or use...but in our dome the second floor is useable.  To learn about useable second floor square footage, click on Second Floor.  A simple lift or rail chair gives you access to the second floor if you don't want to walk up the stairs.  Click on Cupola to learn about it and third floor lofts.

The following gives you a recap of how many bedrooms and bathrooms typically fit in each diameter dome.  The diameter of each dome is in feet.  Ai gives square footage by room and by floor and Ai includes a to-scale ruler and to-scale furniture so you can learn about the spaciousness of the domes.     

22' dome is generally a one car garage dome. Although Ai now has a stock 22' one bedroom/one bath house plan. The 22' standard insulation is 3 1/2". To upgrade to 7" EPS add $1,425.

27' and 30' Domes are a one bedroom/one bath size home.  The 27' can have up to 780 sq.ft. on two floors and the 30' can have up to 1,089 sq.ft. on two levels.  The 27' dome is a two frequency dome which causes the triangles to be larger than the 30' triangles.  The 30' dome thru 48' domes utilize the three frequency dome geometry.  As a result of the larger triangles in the 27' dome, its second floor can have window dormers.  The 30' dome second floor cannot have window dormers.  To have opening windows on the second floor of a 30' dome, use a cupola and install your locally purchased windows in it.

The 27' dome can be designed as a two car garage dome with a garage door 16' wide.

36' Dome is a two bedroom/two bath size home that can have up to 1,664 sq.ft. on two levels.

40' Dome is a three bedroom/two bath size home that can have up to 2,176 sq.ft. on three levels.

45' Dome is a three to four bedroom/three bath size home that can have up to  2,758 sq.ft. on three levels.

48' Dome is a three to five bedroom/three bath size home that can have up to 2,758 sq.ft. on three levels.

60' Dome is generally for a business and can have up to 5,180 sq.ft. on three levels.  All 60' dome plans are custom plans.

If you do not see a stock plan that fits your lifestyle, our designers can modify a stock plan or design a custom plan from your sketches.  Click on Stock/Modified/Custom to learn more.

Ai uses Greek words (Omega, Alpha, Delta) and numbers (21, 22, etc) along with the dome diameter to name our plans. For example 27 Alpha 11: the first two digits are the dome diameter in feet, a Greek word and then a number.

Would you like to design your own Dome Floor Plan?  If you know how to use a Computer Aided Drafting Program (CAD) and if you do not see a stock plan in American Ingenuity’s Dome Stock Floor Plan Booklet that fits your needs, you can now order CDs of American Ingenuity’s Stock Floor Plans in DXF format and design your own floor plan.  By purchasing the CD, you can modify an A.I. stock plan or produce sketches that American Ingenuity can use to design your custom Building Plans.

When you purchase a CD of DXF files we include a bonus item…..a DXF file of a six inch in diameter Mini-Dome.  Not only will this model be fun to put together, but that it will also serve as a reliable reference for building a life-size dome.  Once the Mini-Dome is assembled, you can see the dome geometry consisting of Hexagon, Pentagon and Riser panels. 

American Ingenuity designs the DXF files using the AUTOCAD program.  In order to manipulate or edit the DXF files you need the AUTOCAD program or a compatible drafting program.   If you do not have AUTOCAD, on the internet there is a free 30 day trial of Delta Cad which is compatible with AutoCAD.  Also you can read and edit the DXF files if you have a photo editor program like adobe or paint shop. And you can read the dxf files but not edit them using Microsoft word and power point. 


American Ingenuity’s Stock Floor Plans are now available on CDs in DXF format.  Each CD contains the DXF files for a particular dome diameter’s stock plans.  Each CD is $10 plus the mailing costs. 

To place your order, please call our office Monday – Friday 9 to 5 eastern time at 321-639-8777.  Let us know which CDs you want, along with your shipping info and your credit card info.

  Origins and terminology of CAD

 per Wikipedia “The Free Encyclopedia”

CAD  originally meant Computer Aided Drafting because in the early days CAD was really a replacement for the traditional drafting board. Now, CAD usually means Computer Aided Design to reflect the fact that modern CAD tools do much more than just drafting.

CAD is sometimes translated as "computer-assisted", "computer-aided drafting, or a similar phrase. Related acronyms are CADD, which stands for "computer-aided design and drafting", CAID for Computer-aided Industrial Design and CADD for "computer-aided architectural design". All these terms are essentially synonymous, but there are a few subtle differences in meaning and application. CAM  (Computer aided manufacturing) is often used in a similar way, or as a combination (CAD/CAM).
