Have you dreamed about living in a super-Green, super strong home? Would you like good living in small spaces? American Ingenuity has the solution for you.  A 498 sq.ft. tiny home.

This 22 foot in diameter dome has been customized from Ai's basic 22' Eco Cottage Kit.  This kit has increased insulation and increased riser wall height from four feet to five feet.  The additional one foot in height increases your loft or optional attic square footage to 127 sq.ft. which is 46 more square feet than is in the  Eco Cottage dome building kit.  The standard insulation thickness for an American Ingenuity 22' dome is 3 1/2".  This kit's insulation size has been increased to 7" R28 insulation resulting in increased energy efficiency.  The dome features a hurricane, earthquake, tornado guarantee.  Kit sale price is $12,899 if American Ingenuity selects the month/week of shipment.  If Buyer selects the shipment date add $645 to the kit pricing.  Regular price is $18,920.  This custom 22’ in diameter dome when finished can have a first floor of 371 sq.ft. with a 127 sq.ft. optional attic for a total square footage of 498.

22 Ft Dome

Pricing includes two sets of Building Plans (value $820), Assembly Manual and a dome kit consisting of all the component prefab panels to assemble the dome shell, one entryway, two window dormers, one door dormer and misc items.  Call American Ingenuity for shipping details.  Engineer seal on the plans is not included.

Each prefab panel’s core is 7" EPS (expanded bead polystyrene) R-28 insulation precisely angle cut to form the geodesic shape.   Applied to the outside is pre-finished one half inch to three quarters inch concrete, reinforced with galvanized steel mesh and fibers.  Applied to the interior is quarter inch Georgia Pacific wallboard.  No wood in or on the shell to rot or for termites to eat or to burn.  No shingles to blow off in high winds.  On site the exterior concrete is primed and painted with latex paint.

The kit assembly begins after the foundation and floor are completed.  The assembly process consists of stacking the panels in place, overlapping and locking the steel mesh of adjacent panels and filling the seams with special formulated concrete.  Finish the wall board seams with cement/perlite mixture.  This simple process produces the structural components, completes the finished exterior surface, installs the insulation and all the interior shell wallboard.  To view a video on the 22' Assembly, please click on Special Hideaway.

The entryways and dormers allow you to customize your home with your choice of locally purchased windows and doors.

The concrete applied in the seams and on the entryways and dormers is sponge finished to match the pre-finished texture of the concrete panels. The dome is primed with concrete primer and then painted with two coats of latex house paint to achieve the color you desire.

The Ai dome kit is a true Do-it-Yourself Kit.  All panels are premarked with numbers and letters to match the building plans and the Assembly Manual.   Of if you desire to hire a builder, he can hire the Assembly Specialist to supervise his workers to get the dome kit assembled with the first layer of concrete in the seams and on the entryways and dormers.  To view Ai’s web site file about the independent Specialist, please click on Specialist.

Prior to assembly of the dome kit, a temporary wooden rib system is assembled using your own 2x4’s cut to specific lengths and steel hubs/bolts/nuts/washers borrowed from American Ingenuity by placing an $455 deposit.  This deposit covers a 4 month rental period ($20 a month thereafter).  Once the dome kit is assembled the rib system is removed with the client mailing the hubs back to Ai to receive a deposit refund.  Triangle Panels weight 155 to 180 lbs. Risers weight 255 lbs.  During assembly the panels are placed with some type of hoisting mechanism.  Lifting spikes are purchased from Ai for a $100.  Hub deposit is refunded once hubs/bolts/nuts/washers are mailed or UPSed back to Ai.  To view American Ingenuity’s web site file that explains the rib system, please click on Support System.

Please contact your building department and ask:

  • if there is a minimum size new house requirement?
  • do they require a garage be built with the house? If so is there a minimum size garage requirement?
  • if there is a minimum insulation size requirement?  Will R14 comply? Or do you need to upgrade to the seven inch thick EPS insulation which is R28?
  • what do they require to issue a building permit?  Do they require engineer sealed plans and an Energy Report?  If so those items can be purchased through American Ingenuity. The Energy Report has evolved into a very specific and technical report that requires Ai to have specific window and exterior door info (frame type, double pane or impact resistant glass), Low E number, U factor, SHGC number to fill out the Energy Report.  This means the dome buyer will shop for their exterior doors and windows and provide detailed spec sheets to Ai about each door and window, their water heater and AC/furnace.
