What does sq.ft. max mean?
Max refers to whether you maximize the second floor square footage by enclosing all of the second floor and only leaving an area open above the stairs.  This results in no high vaulted ceilings in any area other than over the stairs. Typically dome owners tend to leave thirty percent to one half of the second floor open; thereby, having high vaulted ceilings over 30% to 50% of their first floor rooms. Leaving 30% to 50% of the second floor open, will lessen the amount of square footage on the second floor versus what is listed above.

How does Ai name its floor plans? Two ways. One way consists of two numbers: Diameter of the dome and a number.  The second way consists of three parts. For example the floor plan named 27 Alpha 11 means; the first two digits are the dome diameter in feet, then the Greek word Alpha and then the two numbers 11. (Call our office to receive via email new stock plans that are identified with numbers not names.)

  • the first part is the dome diameter in feet (22′, 27′, 34′, 36′, 40′, 45′, 48′, 60′)
  • the second part is a Greek word (Alpha, Beta, Delta, Epsilon, Gamma, Kappa, Omega, Omicron, Sigma, Theta, Zeta)
  • the third part is two numbers (11, 21, 22, 32, 33)

What size Ai Domes are best used for garages? The 22’ dome is a one car garage with loft storage. The 27’ dome can be a two car garage with loft storage. You can use other size domes depending upon you parking, storage and work shop needs.

Does American Ingenuity manufacture basement kits? No. But sometimes it is practical for our clients to build their domes on basements. Therefore we have basement plans available. We usually call these basement floor plans “Optional Basement Floor Plan.” It is called Optional because it is up to each client whether they want to build on a basement or not. If they do, then the client purchases the Basement Plans designed for that particular dome floor plan.  Click on Basements to learn more.

How many bedrooms and bathrooms can the different dome sizes have? The number and size of the bedrooms and bathrooms is up to each client.  Click on Stock Plans to view the stock plans for each of the ten different dome kit sizes Ai manufactures.  If you do not find a stock plan that fits your lifestyle, our design team can modify a stock plan or design a custom plan from your sketches and descriptions. The floor plan layout lists the square footage by floor.

The following bedroom and bathroom breakout is typical for each of the size domes after the kit is assembled and locally purchased materials are installed to finish the home.

  • The 15′, 18′, 22′ & 30′ domes are one bedroom, one bath size.
  • The 27’ dome is two bedroom two bath size.
  • The 34’ dome is a two bedroom, two bath size.
  • The 36′ dome is a two bedroom, two bath size (or three bedroom).
  • The 40’ dome is a three bedroom, two bath size.
  • The 45’ dome is a three or four bedroom, three bath size.
  • The 48’ dome can be a four or five bedroom size dome with either three or four bathrooms.

Q: How do we determine what size dome is best for our family?
A:
First review the stock plans to see how the area within a dome is used. Then compare these sample floor plans with the rooms and square footages of houses you are familiar with by printing out the layout and cutting out the to-scale ruler to measure the rooms.

Compare your finances and construction costs to avoid designing a project that is beyond a realistic budget. Think about the future…will you need to increase or decrease your space? If you had to move what size home would sell best?  Click on Financing to print out a Financing Booklet.

Q: Can the dome be made handicap accessible?
A: Yes. All of the dome floor plans can be modified to be handicap accessible. Use a chair rail, lift or elevator to access the second floor. Normally the guest bedroom, guest bathroom and storage are put on the second floor.  Click on Handicap to learn more.

Q: How do I plan for expansion – the addition of another dome at a later date?
A:
When designing your first dome, you can prepare for future expansion by installing a link at the location where you will later connect another dome. If we are providing you with customized plans we can design them for the future expansion.

Q: Do you have separate garage dome kits available?
A:
Yes. We have developed two new garage dome sizes, 22′ and 27′. These garage domes are two frequency icosahedron geometry. This geometry differs from our other domes in that it utilizes fewer but larger panels. By having larger panels we can create a wider opening that is needed for a garage door. You can install a 9′ wide garage door in the 22′. The 27′ garage dome can have a 16′ garage door and it can have a second floor of 398 sq.ft. Previously a 34′ dome was needed to pull two cars in side by side. Now you can have a two car garage in a 27′ dome which is more cost effective. The 22′ dome provides an economical one car garage using 3 1/2″ E.P.S. insulation (R-14). Either of these garage domes can be connected to another dome or built independently from the house.

The 34′ garage dome is utilized when you want more first floor perimeter room around the vehicles or when you want a second floor above the garage for an apartment or study, etc.  Ai has examples of different size domes utilized as garages.  To view the garage plans, click on Stock Plans and scroll down the page to find the garage plans.

You can find the pricing for the plans and the dome kits for each stock plan by clicking on Plans and Kit Sale Pricing.

Q: Will l feel closed in, in the dome?
A:
No. In our dome you can install an abundant number of windows and doors. Your budget and your floor plan selection determines the number of doors or windows you will have. There can be up to five entryways on the first floor of the 30’, 34’, 36′, 40’, 45’, 48’ domes and up to five window dormers or door dormers on the second floor of our larger domes, 36’, 40’, 45’, 48’.

Remember on site  a 2×4 wall is constructed under the entryways and dormers to install standard doors and windows which are purchased locally. For example under a 40′ entryway you could have up to three French doors or a door and a picture window or a large picture window or 12′ of sliding glass doors, etc. In other words on the first floor of a 40′ dome you could have a maximum of five entryways with each one containing 12′ of French doors.

We have a window and door specification sheet on this web site which lists the maximum window sizes that can fit within the entryways and dormers for each size dome. Click on Window Sizes to view this info.  Also during plans design, we email elevation views showing the rough opening size in the entryway and dormers and recommend door and window sizes.

Q: What is a cupola?
A:
A Cupola is “sort of like a hat with windows that sits on top of the dome”. When a person wants to have a third floor loft in the 40′ or larger domes, the cupola adds about 2′ of headroom to the top center of the dome. The top five pentagon panels rest upon 18″ tall concrete “legs” that are built on site. Between the concrete “legs” framing is built to install rectangular windows that you purchase locally. See the floor planners in the Stock Plans for loft heights and square footages.

Cupolas are not necessary for ventilation and extra light. Domes do not need more light than conventional houses. If you build your dome without a cupola, we recommend installing a vent in an interior wall near the peak of your dome for ventilation. The electric fan vent has the added advantage of being easily controlled with a switch or timer.

The outline of the third floor loft matches that of the cupola. In wind areas you do not want the cupola windows to be more than two feet tall. Also taller cupolas just look out of proportion on the dome.

To protect the windows during high winds, the dome owner will either need to purchase windows made from impact resistant glass or have shutters installed.

Q: Why do the square footages on the Specifications Page differ from the square footages listed on the stock floor plans?
A:
On the Specifications Page the first floor and second floor square footage listed is the maximum amount of square footage possible. The first floor square footage is maxed out because only one entryway is considered. The second floor square feet (sq.ft.) listed is what is possible if you only leave open one fifth of the second floor. This means you would only have high vaulted ceilings over one fifth of your first floor rooms. The first floor ceiling height would then be 7 1/2′ in the 30’ and 34′ domes and 8′ tall in the larger domes. You can purchase a five foot riser wall and increase the ceiling height by one foot on the first floor of the 22’ through 48’ domes. This increase in height will not affect the ceiling height on the second floor.

The first floor square footages on the stock floor plans varies from the Specifications Page because more than one entryway is installed. Each time another entryway is utilized on the first floor this will reduce the amount of total first floor square footage. In the stock floor plans the second floor square footage varies from the Specifications Page because some stock plans have one third of the second floor left open while others can have up to half of the second floor not installed. The second floor square footage on stock plans consists of all the illustrated second floor space to five feet of height. On site the second floor knee wall is built along the dome perimeter out 2×4’s and covered with drywall to a height of two to three feet. AC ducting and second floor suspension rods can be hidden behind the knee wall. Electrical outlets can be placed on the knee wall.
