Sauna.

American Ingenuity’s design team, can design the layout of your home to match your lifestyle.

Just give us a list or a sketch of what you desire – sauna – jacuzzi…..

and Ai will design in your ideas to fit the dome geometry

The interior framing of the dome is built much like conventional housing and can be either wood or metal. Some of the second floor will be supported by first floor load bearing walls…such as walls in a bedroom and bath. Plus some of the second floor can be hung from the dome concreted seams by suspension rods allowing for very “open” first floor plan designs. These suspension rods and plates can be purchased from Ai.

The American Ingenuity dome is capable of supporting a weight from the dome shell. This weight is suspended by threaded steel rods which anchor into the concrete seams and extend vertically down into the dome. 3,000 lbs. can be supported by a 5/8″ threaded rod suspended in one of the concrete seams. The location of the suspension rods is determined by your floor plan selection.

The Building Plans will show the suspension rod’s positioning. When the dome shell kit is assembled install the suspension plates and rods into the dome shell seams. The suspension rod with nut sets on a 3″x 7″ steel plate, which is embedded in the concrete seam. The seam is reinforced with #4 rebar & two layers of galvanized steel mesh. The second floor can support at least 55 pounds per square foot, the same as other houses. We can easily design for a more demanding second floor load such as for waterbeds, whirlpool tubs, spas, libraries, etc.

Almost all of the electrical and plumbing will be contained in the interior frame walls and installed in the same manner as conventional housing. To install electrical wiring in the exterior dome walls: simply cut a groove in the E.P.S insulation and wall board and insert the wire or conduit to run the wire through. To install electrical boxes, conduit or plumbing pipes: cut the E.P.S. insulation and wall board slightly larger than needed, insert the box or pipe and fill in the opening with spray expanding foam. The spray foam will harden in about half an hour, holding the box or pipe secure.

AC/Heating Ducts: We leave the AC ducting diagram to your subcontractor, but generally the ducts run through interior walls, in the second floor joists and or behind the second floor knee wall. In the perimeter second floor knee wall a grate with filter can be installed to return second floor air to the air handler.  A separate duct brings cool air to the second floor.  The vents are either in the interior walls or in the floor of the second floor.  Exhaust Fans are installed in various places in the dome; top center of the dome, in each bathroom, for stove, microwave and clothes dryer.

Shell Wall Board:  The interior of the Ai prefabricated panel consists of Georgia Pacific 1/2″ DensArmor Plus adhered to the E.P.S. with drywall adhesive. It employs fiberglass mat facing instead of paper on both sides of the board. The core is fiberglass treated gypsum providing excellent moisture resistance, Fire resistance and adhesion properties. It doesn’t provide fuel for an accidental fire.

To learn more about the drywall’s properties click on DensArmor Plus.

The glass mats embedded into core on both faces, results in dimensional stability and prevents warping. The glass mat is encapsulated with a coating which reduces skin irritation from exposed glass fibers. The moisture-resistant inorganic core has superior mold, mildew and fire resistance.

How is the Shell Wall Board Finished: Use tape and joint compound in the seams with joint compound skip troweled over the drywall to hide panel seams.  Or sand or vermiculite can be mixed in paint to blend seams to the panel. Info to blend the seams is included in the Manual.

Will l feel closed in, in the dome? No. In Ai’s 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. There can be up to five entryways on the first floor and up to five window dormers or door dormers on the second floor of our three frequency domes – 34, 36, 40, 45, and 48.

On site construct a 2×4 or 2×6 wall within the entryways, dormers and cupola to install locally purchased standard doors and windows. 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.

Click on Window and Door Sizes to see what window and door sizes will fit in window dormers and door dormers.

Q: How do we determine what size dome is best for my family?

A: First check the 10 Steps to Building Ai Dome and second review stock plans on our website to see how the area within a dome is utilized

  • To view info to assist in custom plan design, click on these four links: Getting Started, Floor Planner Guidelines, Revising Stock Plans and Things to Consider.
  • Then compare these sample floor plans with the rooms and square footages of houses you are familiar with by using the to-scale ruler in the back of the booklet or on the emailed plan.
  • Compare your finances and construction costs to avoid designing a project that is beyond a realistic budget. On our home page, download our Financing Booklet.  FYI, a smaller dome could be built first with a link where a second dome can be added later. 
  • Think about the future will you need to increase or downsize your home size?
  • If you had to move what size home would sell best?

Q: Does American Ingenuity have an engineering statement about your prefabricated dome panels that can be submitted to my building department?

A:  Yes, to view the statement click on Engineering.

Q: What size dome do I build if I do not want a second floor?
A:
The 15′, 18′, 22′, 27′, 30′, 34, 36′ and 40′ domes would be suitable for homes with only a first floor. However any of the domes can be built without a second floor.

Because of the shape of the dome, a second floor is a natural. If you choose to construct a larger dome and include the second floor, you can install an elevator, chair rail on your stairs or a lift to access the second floor. Click on Rail Chairs to learn more.

You could design all your living space and master bedroom and bath on the first floor, and put a guest bedroom and bath on the second floor and use the second floor rooms for guests or for storage.

Q: Can the dome be made handicap accessible?
A: Yes. All of the dome floor plans can be modified to be handicap accessible. The cost to do this depends upon the complexity of the plan. Contact us for a price quote. Click on Accessible to learn more.

Ai’s philosophy is that each person pay for only what they need.  Ai does not burden the price of the building kit with plan’s pricing, engineer seal cost or energy report cost. Building plans are purchased  three months to 1 1/2 years prior to kit shipment.  About 50% of the building departments require engineer sealed plans and an energy report to issue a permit. As a result each customer pays for their plans separately from the building kit and pays for a seal and energy report only if their building department requires them.

Q: What items should I consider when planning to build an American Ingenuity geodesic dome?
A:
The building industry is not only behind the times, it moves slowly! We cannot stress enough the importance of starting your preparations early for all aspects of building. What you think may take two months can easily consume four or five months or more. To have any hope of beginning the actual construction on time you must at least double the time you think it will take to acquire blueprints, financing, building permits, contractors or subcontractors. Optimists should triple their expectations.

Once your land has been acquired, blueprints are usually the first step.

  • Some Building Departments require that blueprints be sealed or approved by one of their state architects or engineers prior to giving permits, which takes additional time. Click on Building Permit to learn more.
  • Mortgage lenders move slower than you may anticipate. Click on Financing Overview to lean more.
  • Remember to allow time to have the land cleared, prepped and ready for the foundation. All permits pertaining to electrical, telephone, water, septic tanks, sewer hookups, driveway and building….will take time. Click on Planning Process to learn more.
  • Also increased demand for American Ingenuity Dome Kits has forced us to assign shipping dates as much as 8-12 weeks in advance. If you intend to begin building in the summer start the process one to two years before. Other expectant homeowners will be clogging the system by spring, so if you are the early bird they will be waiting behind you instead of vice versa.

Q: How do I plan for expansion -building an additional dome at a future date?
A:
When designing your first dome, you can prepare for future expansion by placing an entryway or 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. When you order your first dome, we can provide instructions and materials that will make the connection easier.

Q: Can the domes have basements or be built upon stilts or pilings?
A:
Yes. To complete these designs, a local engineer is hired to calculate the load of the dome and its interior floors to determine joist size and spacing and wall/column/piling design.  Ai then incorporates his designs into your building plans.  Call for engineer pricing.  Any of our domes can be built upon a basement, stilts or pilings. You determine how many openings you want in the basement walls for garage doors or for windows and doors, and you determine if and how many of the basement sides you want bermed with dirt. Full basements are the same size and shape as the dome first floor. Click on Foundations to learn more.

Also what do you use for floor joists? Wood, steel, manufactured trusses, whatever you prefer. How thick of a basement wall is required for the domes? Basement walls are usually 8″ thick when made of poured concrete but will likely increase depending on the height of the basement wall and the height of the backfill.

Ai can provide a design, which places the dome on concrete pilings. Sometimes Ai recommends an above ground basement with breakaway walls instead of pilings.

Bear in mind that building any structure upon pilings will increase the cost significantly and require you to climb a flight of stairs each time you go in the house. If in your location, it is a requirement then you have no other choice.

Q: Do you sell basement wall kits?
A:
No. Ai manufacturers dome housing kits. We do not manufacture or build basement walls. Although we do design the basement building plans using premade wall panels, ICFs or concrete blocks. You would need to contact a local subcontractor for basement construction costs and to find out what type basements are best built in your area.

Q: What is the standard foundation included with the stock plans?

A: Concrete slab. For Ai to design a basement or concrete columns or stem wall or pilings, etc. an engineer fee is added to your Plans Quote. This is to cover the cost for a structural engineer to calculate the load of the dome and the load of the two floors within the dome and give joist/edge beam size/spacing and foundation design to our CAD department to incorporate within the plans. Call for engineer pricing.

Q: Can I have windows above doors in an entryway?
A:
Yes. By using high profile entryways in your building plans, you can include glass or standard windows over a door, set of doors, or bank of conventional windows. The glass above the doors or windows could be half-moon shaped or be stained glass, etc. Any room with a cathedral ceiling, such as a foyer or living room, can benefit from this striking architectural feature. Click on Window Sizes to learn more.

Q: Will l feel closed in, in the dome?
A:
No. In our domes you can install an abundant number of windows and doors. Your budget and your floor plan selection determine the number of doors or windows you will have. There can be up to five entryways on the first floor of the 30’ through 48’ domes and you can have up to five window dormers or door dormers on the second floor of the 27’ or 34’ through 48’ domes.  (No second floor window or door dormers are available in 22’ or 30’ domes.  If there is a first floor standard entryway, there can be a second floor door dormer above it.  Instead of installing a door, install a tall window (2’x5’) to let light in a room or to let light into a high vaulted ceiling area.

 Q: Do your Building Plans come with an Engineer’s seal?
A:
No. Although over 30 different engineers have reviewed our Building Plans, the plans do not come with an engineer’s seal for the following reasons.
 

Less than half of our dome owners need engineer sealed Building Plans to obtain a building permit and rather than adding the engineer cost to all plans or burden the price of the building kit, it is more economical to have the plans sealed as needed.

  •  As the designer and manufacturer, we would not hesitate to guarantee the structural integrity of our dome and we do just that with our guarantee.
  • Each state only accepts a seal from an engineer who is registered in that state which prevents us from applying any seal that would be universally accepted.
  • When an engineer seals a set of plans he is taking responsibility for the structural design for a single dome in the location intended and the seal would not apply to other projects.

Q: What format do I email floor plan drawings to you?
A:
jpeg format or bmp format (windows bit map). Alternatively, if you are using AutoCAD, we can accept the documents in dxf format or dwg format saved in 2013 or older program. Please include your name, telephone number and the best time(s) to contact you.  

Q: What programs can I use to read dxf format?
A:
You can read and edit the dxf files if you have AutoCAD program, any other computer aided drafting program, a photo editor program like adobe or paint shop. You can read the dxf files but not edit them using Microsoft word and power point. The web site http://www.deltacad.com has a computer aided drafting program that can be downloaded and used  free for 30 days.

You can use computer programs to draw your floor plans; although, we can use a hand drawn sketch that is faxed to us just as easily as a CAD drawing. We have to reenter all of your information into our system and we will likely agree upon some changes for your benefit.

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 Floor Plan Booklet for loft heights and square footages.

The topside exterior of the five panels of the cupola and the underside exterior of the eave are prefinished, while the topside and edges of the eave are stuccoed onsite.

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.

For an observatory on top of the dome, you would not need a cupola. The top or any part of the dome will easily support the weight of people. All that would be needed would be a railing around the top and some way to access the top of the dome, i.e. sculptured concrete steps. Click on Building Options to learn more. 

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 built in the second floor leaving only one fifth open to the first floor. The first floor ceiling height would then be 7 1/2′ in the 30’ and 34′ domes and 8′ tall in the larger domes.

The first floor square footages on the stock floor plans vary from the Specification Page because:

  • More than one entryway was designed in each of these plans. Every additional entryway on the first floor of the dome will reduce the 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 left open. Providing you with a dramatic high-vaulted ceiling over your first floor living and dining rooms.
  • The second floor square footage on stock plans consists of all the illustrated second floor space to the knee wall. 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.

Residential Building Plan sets contain all the blueprints typically provided with any type of housing and include floor plans, exterior elevations, dome shell section view, top view showing panel nomenclature, floor joist framing plans, structural details, and locations for plumbing and electrical fixtures.  To view stock plans for each of our ten different size dome kits, click on Stock Plans.  If you do not see a plan to fit your lifestyle, Ai can modify its stock plans or design custom plans for a reasonable fee. 

If you do not have the time or do not want to assemble the dome shell kit, American Ingenuity knows of a Kit Assembly Consultant that will come to your site, and supervise your laborers or your contractor’s laborers and get the dome shell kit assembled with one layer of concrete in the seams and on the entryways and dormers.

Q: Prior to purchasing Residential Building Plans, what do I need to consider?

A: You need to assure you have answers to the following questions:

  1. Does the deed for your land have any restrictions on domes?
  2. Are you within 1-2 years of building?
  3. If there is a Home Owners Association governing your land, you will need to check with them and make sure you can build a dome.
  4. What is required from your building department to obtain a building permit?
  5. Do you have your financing secured?
  6. If the answers to the above questions are positive then you can fax or email us your modified sketch.

Q: If I purchase Building Plans for one size dome and later change my mind, can I get a refund?

A: No Ai cannot issue a refund.

Q: When should we purchase our dome building plans?

A: Ai recommends that our clients design their floor plan when they are one to two years from building their dome. If you design your plan before then, you may see model homes or get ideas from other plans that may cause you to want to change your original floor plan ideas.

Q: When can I move into my dome?

A: If you have to obtain a building permit before you can build, then you have to submit a set of Building Plans. If you do not have to obtain a building permit then you can move into the dome once the shell is weather tight. But typically the building department will not allow you to live in the dome until the interior and exterior are finished per the building plans.

Q What are the contents of your Residential Building Plans? A: Stock sets generally have 13-17 pages per each set. Building plans include the basic drawings for the dome that are needed when acquiring a building permit. They are composed on our computer aided drafting system as stock plans, or based on your individual requirements and design. Some of the pages are a 3-D elevation and a 3-D perspective view.

American Ingenuity’s Building Plans contain all of the typical drawings and details – usually 13-17 sheets. The blueprints included in your plans are based on the type of entryways, dormers and foundation that are designed in your plans. Some of the Blueprint names are:
• Cover Sheet
• Legend Sheet
• First Floor Plan
• Second Floor Plan
• Dome Panel Nomenclature
• Exterior Elevations
• 1st Floor Electrical Plan (shows location of electrical outlets, lighting fixtures, smoke detectors)
• 2nd Floor Electrical Plan (shows location of electrical outlets, lighting fixtures, smoke detectors)
• Foundation Plan
• Foundation Details
• 2nd Floor Framing Plan
• Typical Dome Section
• Standard Entryway Details
• High Profile Entryway Details
• 1st Floor Window Dormer & Door Dormer Details
• 2nd Floor Dormer Details
• Stair Details
• Cupola Blueprint if ordered
• Link Blueprint if ordered

These plans include all the structural drawings, show the placement of the electrical outlets, light fixtures, plumbing fixtures; however, they do not have the electrical, plumbing, HVAC layouts. We have found if the layouts are included, then the inspectors require the subcontractors to follow the diagrams when the subs like to design their own layouts.

Q: Do your Building Plans include the electrical, plumbing and HVAC diagrams?

A: No. Ai has found if these layouts are included, then the inspectors require the subcontractors to follow the diagrams when the subs like to design their own layouts based on their installation method. Ask you building department if these layouts are required for you to obtain a building permit. Ai will email finished floor plan layouts in pdf so your subcontractors can design the layouts.

Q: Why do you charge extra to modify your stock Building Plans?

A: If there is no change to load bearing walls, there will be no extra fee.  However quite often our clients send us sketches that require the load bearing walls to change. This change then affects the foundation sheet, the second floor framing sheet and other sheets.  Some of the footer locations in the concrete slab foundation are based upon the location of the first floor load bearing walls, which help support the second floor. Plus the dome riser panels set on a perimeter footer in the slab. Also parts of the second floor are suspended by rods into the dome shell. These rods are inserted and buried in the seam concrete during the shell assembly. So we need to design your floor plan per your sketch and then design the structural sheets that the slab subcontractor, shell assembler, framer, etc. need to follow. So yes you would pay us a fee for us to modify our stock plans per your sketch and produce sets of building plans.

Q: I understand that you can suspend parts of the second floor from the dome shell so we can have an open first floor plan. Is this true?

A: Yes, the second floor can be suspended from the dome shell and allow you to have as open a first floor as you desire. Keep in mind that it is more economical to use some of the first floor walls as supports. Long spans with floor joists will require more expensive materials to provide the strength for suspension rods that pass through the second floor.  The suspension rods and plates are purchased from American Ingenuity.

Q: How is the square footage determined in the Dome Plans?

A: Remember in a conventional house you have an attic that cannot normally be used. Because of the dome shape a second floor can be installed that is useable. So even if some square footage around the second floor perimeter cannot be used there is still more useable square footage in a dome than a conventional house with attic under truss roof.  Building Plans second floor square footage includes the area starting at five feet to the top of the dome. For example in 27′ dome the center of the 2nd floor is 9’1″ tall; the center of the second floor in 36′ dome 10 feet tall; the center of the second floor in 45′ dome is 13 feet 7 inches tall.  The second floor square footage is calculated from the top of the dome down to where the exterior dome walls slope to five feet.  Around the perimeter of the second floor at the five feet of height, bed headboard, or night stands, or desk or dresser can be placed.  The Tax Assessor uses these numbers, so your taxes will be less.

Click on Square Footage to learn more.

Q: I am concerned about having a second floor and using the stairs. What do you recommend?

A:  Ai can design a dome floor plan layout without a second floor.  Because of the spherical shape of the dome a second floor is a natural. To access the second and third floors instead of an elevator, install an electric winch powered lift in a 4’x4’ area or an elevator to get to the second floor, or you could use a stair railing chair. You could design all your living space and master bedroom and bath on the first floor, and design a guest bedroom and bath on the second floor and use the rooms for guests or for storage.  Click on Lifts and Elevators to learn more.

Q: I understand that very few of your clients ever sell their dome. As a result, the dome ends up becoming a retirement home, should I make it handicap accessible?

A: Yes. It is a easy modification to the plans to make the entire downstairs area wheelchair accessible, (32″ or 36″ doorways, handicap accessible shower stall, bathroom, etc.).

Q: How are two domes joined together and should I plan extensions onto my Entryways?

A: If you are planning a complex of domes, the plans are joined at entryways or door dormers to form a link. The link will vary in width according to the size of the domes’ entryways and can vary in length from 2 feet to 10 feet.

While many companies offer the alternatives of large links and room extensions to the dome, American Ingenuity feels they are not in your best interest. Among the reasons:

  • When floor space is increased using an extension or link, the exposed surface area is greater than for the square footage within a dome. This results in less energy efficiency and a higher cost per square foot.
  • Construction is more involved and time consuming
  • The overall scale, relationship between elements and proportion of the home are adversely affected.
  • The visual impact of the design is lessened.
  • Good chance of leaking where the extension long flat roof butts into the dome shell. The expansion and the contraction associated with temperature changes produces the flex or separation at the link. We have considered expansion joints but they are not trouble free either. We have concluded the adding of elastomeric patching compound with exterior paint where the link panels touch the dome panels is the best solution.  
  • Ai recommends simply moving up to the next larger size dome or arranging your space differently to increase the efficiency of your design. It will save time, energy and money.

Q: What do your building plan names mean?

A: The first two numbers are the dome diameter in feet, the next word is a Greek word (Omega, Alpha, Delta) and then we use two numbers (21, 22, etc) to complete the name.

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.
