The American Ingenuity Dome Kits
are DIY Prefab Dome Homes for Owner Builders or for a Contractor

The prefab dome kit can be a Do It Yourself Project with the owner builder utilizing family and friends or hiring his own workers for kit assembly.  Or the home owner can hire a builder who hires the independent Kit Assembly Specialist who travels world-wide to supervise your kit assembly and the application of the first layer of fiber concrete into the panel seams and onto the entryways and dormers. Then either your workers or your builder’s workers complete the second layer of concrete in the seams & on the entryways and dormers. For interior finishing complete yourself or hire local subcontractors to complete the plumbing, electrical, framing, window/door installation, wall board finishing, kitchen cabinetry, bathroom fixtures, etc.  To view pictures of prefab concrete panel assembly, click on Dome Kit Assembly.

American Ingenuity’s (Ai’s)dome kit is affordable, strong and can be assembled by Do It Yourself individuals because the kit is engineered as a system of pre-finished prefabricated component panels. Each panel is cut at a computer-generated angle so that it fits flush with the adjacent panel. The edges are precisely beveled at the seams where steel and concrete will unite to complete the structure. All panel materials are noncombustible and contain no food source for mold growth.

Building an Ai dome from prefab concrete panels makes home construction easier than stick built construction and results in the dome exterior having a 225 mph wind and F4 tornado guarantee. The process of stacking the panels, overlapping/locking the steel mesh of adjacent panels and filling the seams with special fiber concrete, produces the structural components of the home, the finished concrete surface, installs the insulation and all the dome shell 1/2″ drywall.

This advanced building system makes it easier for an owner builder to construct an American Ingenuity dome than a conventional house or a wooden dome. No exterior walls, no roof trusses, no sheathing, tar paper, or shingles, no soffit, exterior trim, insulation or siding to install and no interior shell drywall to install.  During the dome kit assembly, owner builders or builders can email pictures of the kit assembly. At no cost to you, Ai will review the pictures and give feedback about rebar and cable installation, etc.  Due to large size of panels in 45′ and 48′ domes, considering hiring the consultant to assist in your assembly.

The building plans contain blueprints for the installation of the foundation and installation and location for each panel. Within the plans is a nomenclature blueprint that shows lettering and numbering for each panel. An example of a nomenclature blueprint is above.

An Expanded Assembly Manual is now available with each dome kit order that explains step by step the panel assembly. (Once a deposit with signed order is received, the manual can be shipped). In the blueprints and Manual is the recipe for the concrete. Ai wants the concrete mixed on site to have the same properties as the concrete that is applied at our factory; as a result the same two liquid admixtures and fibers are shipped with each kit. In the manual is a list of tools and materials to have on site. To view a list, click on Materials and scroll down the page to view the list.

American Ingenuity’s prefabricated component panel consists of:

1.   7″ thick, rigid, nontoxic E.P.S. Insulation (not Styrofoam): The E.P.S. Ai utilizes is a closed cell with a 1 lb. per cubic foot density.  Seven inches of sturdy, rigid R-28 expanded polystyrene foam insulation forms the core of each component panel and is:

  •  Permanent
  • Chemically/thermally stable
  • Resistant to mildew and mold
  • Provides no nutritive value to animals/plants/microorganisms
  • Non-irritating to the skin
  • The insulation will not rot, shrink, absorb moisture, compact, or deteriorate due to age or the weather.
  • No CFC, no HBCD (hexabromocyclododecane), no TCPP (1-chloro-2-propyl) phosphate, no Chlorofluorocarbon (CFC) and no Formaldehyde

2.     Concrete: the concrete in your dome out performs other exteriors due to our specially developed formula. Because of this exceptional composition, it actually gains strength over the years. The special concrete formulation of fibers and admixtures improve concrete characteristics.

3.     Galvanized Steel: Galvanized steel wire mesh is encased in the concrete of each panel. As your dome is assembled the mesh of each panel overlaps and is locked to the mesh of  adjacent panels with C rings commonly called hog rings – resulting in your home being completely wrapped by steel mesh.

4.   Half inch (½” ) Georgia Pacific DensArmor Drywall: The DensArmor is not conventional sheet rock. Conventional sheet rock consists of conventional gypsum and paper backing. The paper backing can be a food source for mold growth. Sheet rock when it gets wet crumbles and molds. The DensArmor gypsum when it gets wet does not crumble due to fiberglass reinforced core. It has fiberglass backing on both sides. After the DensArmor dries out it goes back to its original firmness and consistency per the manufacturer.

Concrete Home
Dome Exterior Has No Wood To Burn or To Rot or For Termites To Eat
No Shingles or Roof to blow off in high winds

To support the panels during dome kit assembly, a temporary wooden rib system is installed. Once all the seams are concreted and the entryways and dormers are concreted, the dome is self supporting and the wooden rib system is removed. Most of the wood can be recycled as interior framing.

45′ dome – assembly of third row of panels

In this view of dome kit being assembled a side view of a component panel can be seen. The panel exterior is 3/4″ concrete reinforced with galvanized steel mesh. After the mesh is overlapped and locked between panels, special fiber concrete mixed on site is hand troweled in the seam areas in two applications — bonding agent is applied between the two layers. The seam areas are about 3″ deep by 5″ wide with average of 2″ thick concrete.  In this picture you see the first scratch coat applied to the exterior of the entryway panels and first layer of concrete in some of the seams between the panels.

Steps for American Ingenuity Concrete Building Kit Assembly:

  • Foundation installed. Standard foundation is monolithic slab; however Ai can design basement plans, pilings or columns, stem wall, etc.
  • Depending on size dome two to five workers are needed. Some with concrete experience.
  • Installing the first row of panels which are the 4’ vertical riser panels, base panels of the entryways and any first floor door dormer base panels
  • Erecting a temporary wooden rib system to support the triangle and riser panels during assembly using your locally cut, drilled and painted 2×4’s bolted to steel hubs borrowed from Ai.
  • Placing the panel’s one row at time using a hoisting mechanism (man lift) on to the rib system.
  • overlapping steel mesh from adjacent panels, locking mesh with C rings and pliers and depressing the steel mesh in the seam
  • mixing concrete with mortar mixer following concrete recipe in the manual (Portland Cement Type III, masonry or stucco sand, fibers, liquid admixtures)
  • installing cables per blueprints
  • installing rebar around back of entryway panels, back of first floor door dormer panels, top of entryway panels & around first floor window dormer panels per building plans
  • form up and install beams or troughs around lip edge of entryway panels, first & second floor door dormer panels, channels in top of the entryways
  • Concreting the seams between the panels (5″ wide and 3″ deep) with two separate layers of concrete using a bonding agent between the layers; and watering down all cured concrete before applying bonding agent or new concrete. Seam areas average 2” thick concrete.
  • Concreting the entryways, window dormers, door dormers, cupola and link with two layers of concrete. Sponge float finish the final layer of concrete to blend seam concrete to the panel concrete.
  • Framing in the entryways and dormers and installing your locally purchased exterior doors and windows.
  • Removing the temporary wooden rib system. Return the steel hubs to receive a full deposit refund if returned during five month rental period and if all hubs are intact.
  • Wash efflorescence off concrete, prime, paint the exterior concrete per waterproofing instructions in Assembly Manual.

Onsite concrete is only applied in the seam areas between the panels and on the entryways, dormers (or possible link or cupola). Concrete is not applied over the pre-concreted component panels. The interior shell drywall can be finished similar to conventional sheet rock with adhesive fiberlass and joint compound. To blend the seams joint compound can be skip troweled over the drywall before priming and painting.

If I am not ready to assemble my dome immediately, can the kit be stored outside? Yes, however if you expect to have your kit outside for more than two to three months, request that the E.P.S. edges be painted. On site if you need longer than 2-3 months prior to assembly, then on site the EPS edges can be painted again. (some boxed items & wooden 2×4 ribs if ordered should be stored inside.) The dome kit should not sit outside in the winter as freezing can harm the drywall.   Please call us for details at 321-639-8777 – Monday – Friday 9-5 eastern time.

The following information covers Tiny Home Kit reg & sale pricing w’ specs.  Ai has added two new tiny home sizes to its Tiny Home assortment – 15′ and 18′!   These Tiny Dome Home Kits are constructed using Ai’s superior prefabricated insulated concrete panel system.  Consider them for Special Hideaway, vacation cabin, mother’s home, guest house, hunting cabin, glambing, tiny home, micro home, cottages for resort, rental units for veterans or a starter home.  The Ai dome is much stronger, has noncombustible materials in its wall panels, fire resistant concrete exterior & more insulated than a framed house, concrete block house, log cabin, tent or yurt.  Also all the panel materials contain no food source for mold growth.

Additional dome kits can be added later and linked to the first dome built on your site.  If you believe you want to add on later, discuss with our design team and a link can be installed on the first dome where a second dome can be connected later.

Tiny Dome Home Kits when assembled and finished can result in 172 sq.ft. to 1,278 sq.ft.  The domes can be one story. Dome sizes are measured by feet in diameter with the 15′, 18′, and 22′ kits having a first floor with optional attic/loft.  The 27′, 30′ & 34′ can have a second floor installed if you so desire. The 27′  dome second floor panels are large enough for a window dormer to accept fire egress size window.  The 34′ second floor window dormer is too small to accept a fire egress window so door dormer panels are installed above a first floor standard entryway to accept a fire egress size casement window.  With a 2nd floor egress window installed this allows the 27′ & 34′ domes second floor to contain a bedroom; resulting in the 27’ & 34’ domes being two bedroom/two bath size homes. The 30′ dome second floor panels are not large enough for a window dormer so no bedroom can be designed – use the 30′ second floor for storage, office, craft area, additional bathroom, rec room.  To view stock plans for the 15′ and 18′ along with plans for the other Tiny Domes, click on Tiny Home Plans.

As far as Tiny Homes meeting minimum size house requirements – in some areas,  groups are petitioning their county or their city elected government officials to allow them to have Tiny Home Communities (called pocket neighborhoods) where the minimum house size can be below state code. The City of Rockledge, Florida agreed that a group whose face book page is called Rockledge Tiny House Community can purchase property and build Tiny Homes from 172 sq. ft up to 1000 sq ft. in their city.   Normally in Florida the minimum new house size requirement is 500 sq.ft. or 800 sq.ft. or 1,000 sq.ft.  So congratulations to the City of Rockledge Tiny House Group for its victory in changing minimum size house requirements in their city to as small as 172 sq.ft..

Please check local codes to see how Tiny Homes can be built for cottages in a resort or for rental units to rent out to migrant workers, veterans and individuals wanting to live in strong (225 mph & F4 tornado warranty), energy efficient houses whose exterior concrete is fire resistant.  To view comparison of concrete dome kit to log cabin, click on log cabin.  To view info on Ai dome and tree impact & snow load, click on Tree.   To view complete summary of advantages of Ai dome, click on Summary.

Where doors & windows are located in the dome, structural awnings called entryways and dormers must be installed. The number of entryways and dormers are determined by your choice of floor plan. Entryway panels consist of 3½” EPS with no steel mesh or concrete. Steel mesh is purchased from Ai and attached on site with panels requiring on-site concreting. Dormers consist of 3 ½” EPS wrapped with steel mesh & require on site concreting. Call for Link pricing. Links can be purchased with 1/2″ DensArmor drywall. Links consist of precut 7” EPS. Steel mesh can be purchased from Ai. The link requires on-site mesh installation and concreting. American Ingenuity Domes are designed with flexibility, allowing you to create your own personal home and floor plan layout. Exterior doors & windows are purchased locally and installed onsite within the entryways and dormers using locally purchased materials. Solar tubes can be installed onsite within a panel. (Do not cut within 8” of a seam).

If you do not see a stock plan to fit your desires, Ai can modify or customize a plan from your sketches and descriptions.  Each Set of Building Plans includes the floor plan layout(s) and consists of 13 – 17 blueprints depending on type of entryways and dormers in your kit.  To view sale pricing on all the stock plans and the dome building kit for each plan, click on Stock Plans & Kit Sale Prices.

Ai’s philosophy is that each Buyer pays 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.

Building Departments vary by state as to what they require to issue a new home building permit.  If you give Ai your parcel ID number & building department name, we will call and email info to them and find out what is required for them to issue a permit.  Will they require the building plans to be sealed and stamped by an engineer licensed for your state? Will they require an Energy Report?  If required these items can be purchased from American Ingenuity. To learn more about building permit, click on permit.

The standard foundation under Ai’s domes is a concrete slab. Other types of foundations; i.e. basements, stem wall, pilings, require the hiring of an engineer. Call for engineer pricing. Each buyer tells Ai the type foundation they want designed.  The foundation type is determined by property terrain, building department requirements and requirements from a soil report.

Plans may be purchased with a credit card, check or money order. Stock plans utilize a concrete slab foundation and are delivered within 2-4 weeks, Allow at least 5 modified plans and 8-10-12 weeks for custom plans.

SPECIFICATIONS

AREA AND VOLUME:   15’, 18’ & 22’ can have attic/loft. 27’, 30’ & 34’ can have second floor. 27’ & 34’ dome second floor can have bedroom because window dormer accepts fire egress window. 30’ dome panels are too small to have second floor window dormer; as a result 30’ second floor can be utilized for rec room, office, craft room, bathroom…not a bedroom.
