The following info covers American Ingenuity’s Garage Domes which have R28 insulation. The 27′, 34′, 36′, 40′, 45′ & 48′ domes can be designed as a garage on the first floor with a second floor studio above.  If the entire second floor is built within a 27′, 34′ or 36′ or 40′ dome, the second floor could be designed for a studio apartment with one bedroom, one bath & kitchenette.  Due to the load of the second floor there could be a post in the center of the first floor if microlam beams are not designed to carry the second floor load.  The 40′, 45′ & 48′ dome’s second floor is large enough to have two bedrooms and one full bath with kitchenette.

American Ingenuity’s 22’ & 27’ domes were specifically designed for garages. The 22′ is a one car garage dome with 9′ wide garage door.  The 27′ is a two medium car garage with 16′ wide garage door.  27′ dome can have a second floor for a one bedroom, one bath studio apartment. These garage domes are two-frequency icosahedron geometry whereas the domes (30′, 34′, 36′, 40′, 45′ & 48′) are three-frequency icosahedron geometry. The two frequency geometry differs from our other domes in that the 22′ & 27′ utilize fewer but larger panels.    For Ai to assure that the vehicle(s) you desire to park in your garage dome will fit, please give us your vehicle length, width, height and hood height.  At no cost to you, our design team will provide a plan proof  showing the vehicle sizes and whether they will fit or not.

Due to the size of the 22′ – 40′ domes three risers can be removed instead of two in order to have a wider entryway.  Due to the large size of the 45′ & 48′ dome only two risers can be removed for an entryway.  Because the 22′ & 27′ have fewer but larger panels than the three frequency domes, their risers are wider resulting in the 22′ dome  accepting a 9′ wide garage door. The 27′ dome can have a 16′ wide garage door.  Previously a 34’ dome was needed to pull two small to medium cars in side by side. Now there can be a two-car garage in a 27’ dome, which is more cost effective.  Either of these garage domes can be connected to another dome via a link that is one riser panel wide or the garage dome can be built independently from the house dome.

Garage Entryways take the place of three riser panels whereas standard and high profile entryways replace two risers. The 45′ & 48′ dome cannot have garage entryways due to their large size.

The 22′ and 27′ Garage Entryway panels are larger in size than the other dome entryways and are not preconcreted. The 22′ and 27′ entryway panels consist of 3 1/2″ EPS as the rigid form with no steel mesh or concrete applied.  The dome buyer can purchase galvanized steel mesh from Ai and at no cost Ai will affix the mesh to the 22′ or 27′ garage entryway panels.  On site fiber concrete is mixed and hand troweled to all sides of the entryway panels after their installation.

An Ai dome building kit includes all the panels for the dome shell and includes the panels for one entryway.  Each floor plan varies as to the number of entryways and dormers.  As a result the kit pricing only reflects the type and number of entryways and dormers that you chose to have in your floor plan.  The following Plan’s Price does not include an engineer seal, structural calculations or energy report.  If those items are required by your building department they can be purchased from Ai for a reasonable fee.

Garage Dome Stock Floor Plans

GARAGE DOME, 22’: has 370 sq.ft. on the first floor and is designed for a one-car garage. A 9’ wide x 7′ tall garage door can fit in the garage entryway. There can be a loft area for storage. Due to small size of the second floor panels, the loft area cannot have any window or door dormers.  A link connected to a 22′ dome is about 5.5 feet to 6 feet wide with a standard length of five feet.

Garage Dome, 27’: has 555 sq.ft. on the first floor sq.ft. and is designed for a two medium car garage. It can have a 16’ wide garage door in the garage entryway. The second floor center height is 8′ 4″ sloping down to five feet to equal 231 sq.ft. on the second floor.  The second floor can have  window dormers but no door dormers. The second floor can have fire egress window; therefore the second floor can have a bedroom.  A link connected to a 27′ dome is about 6.75 feet wide with a standard length of five feet.

Garage Dome, 30’: has 638 sq.ft. on the first floor and is designed for two small cars with the cars pulling in one at a time and each car parking on a diagonal. The 30’ garage door is 12’ wide. The second floor center height is 7’4″ sloping down to five feet to equal 213 sq.ft. on the second floor.  Due to small size of dome’s second floor panels the second floor cannot have window or door dormers.  Therefore no bedroom can be designed on the 30′ second floor.

Garage Dome, 34’: has 846 sq.ft. on the first floor and is designed for a two-car garage with the garage door being 14’ wide. The second floor center height is 9’5″ sloping down to five feet of head room to equal 427 sq.ft. on the second floor.  The second floor can have window dormers & door dormers.  If balcony desired the door size is 2′ x 6′ tall with this door being custom cut on site.  The second floor can have a bedroom and bath.  For fire egress second floor window to fit a second floor door dormer has to be installed above a standard entryway. Instead of installing a door a fire egress size casement window is installed.

Garage Dome, 36′: has 940 sq.ft. on first floor and is designed for a two-car garage with the garage door being 14′ wide. The second floor center height is 10′ 4″ sloping down to five feet to equal 470 sq.ft. on the second floor.  The second floor can have window dormers & door dormers. If balcony desired the door size is 2’x6’8″ and is custom ordered. The second floor can have fire egress size window & is large enough to have a bedroom with bath.

Garage Dome, 40′: has 1,160 sq.ft. on the first floor and can be designed for a three to four car garage depending on the vehicle sizes. It would require two garage doors, each could be 16′ wide. Each set of two cars would share one garage door. The second floor center height is 10’4″ sloping down to five feet to equal 667 sq.ft. on the second floor.  The second floor can have fire egress windows and door dormers above standard entryways.  The second floor is large enough to contain two bedrooms and one bath.

Garage Dome, 45′: has 1,489 sq.ft. on the first floor and can be designed for a three to four car garage depending on the vehicle sizes and entryway locations.  It would require two garage doors, each 13′ wide.  The second floor center height is 13’7″ sloping down to five feet to equal 951 sq.ft. if the second floor is maxed out.  The second floor can have fire egress windows and door dormers above standard entryways.  The second floor is large enough to contain three bedrooms and one bath.

Garage Dome, 48′:   has 1,693 sq.ft. on the first floor and can be designed for a three to four car garage depending on the vehicle sizes and entryway locations.  It would require two garage doors, each 14′ wide.  The second floor center height is 14’10” sloping down to five feet to equal 1,137 sq.ft. if the second floor is maxed out.  The second floor can have fire egress windows and door dormers above standard entryways.  The second floor is large enough to contain three bedrooms and one bath.

Q: What is the tallest and widest garage door you can have and in what size dome?
A:
Current designs allow for a 16′ wide 9′ tall garage door in a 40′ dome with a 4′ risers with additional 2′ risers.  A 27′ dome because it is two frequency can have 16′ wide garage door 7′ tall with a four foot riser.

Q: Can the 45′ and 48′ domes be designed for a garage dome?
A:
Yes.The standard entryway in the 45′ with 4′ risers can have a 13′ wide x 7′ tall garage door for a two car garage. The cars would go in and out of the garage one at a time. In a 48′ dome there can be a 14′ wide garage door in a standard entryway and the cars come and go two at a time.  Due to the large size of the domes for structural integrity three risers cannot be removed ONLY two.    If the 45′ or 48′ dome are built with two foot additional risers the garage door for a 45′ can be 13′ x 9′ or 15′ x 7′.  The Garage door for the 48′ dome can be 14′ x 9′ or 16′ x 7′.

Q: What is the cost to build a garage dome?
A:
The cost to build a dome garage would be about the same as the cost of a garage for a conventional house. Whatever it costs per square foot in your neighborhood to build a conventional garage that will be the approximate cost to build the dome garage.  The construction cost will increase if a bedroom and bath is installed on the second floor above the garage.

Q: Are garage plans priced separately from the other plans?
A:
Yes since every building site is different, Garage & Basement Plans are priced separately from the dome home plans. Ai has Stock Plans for garages which may be linked to any dome where indicated or may be built separately. Or Ai can design custom garage plans.

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.



Q: What is the dome diameter and square footages converted to meters?
