Construction Cost Estimates

The following blank form is provided for you to fill out as you determine your material and labor costs for your dome kit assembly and finishing. Because labor costs and materials cost vary in the USA, we cannot estimate your costs. If you select one of American Ingenuity's stock floor plans, you can obtain the Building Kit with Option Pricing by clicking on Plans & Kit Prices.   To view our current kit discount, click on Savings.

The following link, Home-Cost gives average cost per sq.ft. to build average house by state.  Just enter the zip code you will be building in to get the average cost to build a house in that area.

If you choose to use the Kit Assembly Consultant to supervise the assembly of your dome kit, click on Kit Consultant for approximate labor costs to assemble the dome shell kit. The rest of the categories (other than foundation) are generally the same costs whether it is a dome or a conventional house. Because of the multisided dome, the foundation will cost 15% to 25% more than a conventional foundation. To give you perspective a 36' dome slab was installed in northern Florida for around $6,000.

The finished costs on American Ingenuity concrete domes depends so much on where you live and what labor costs are for your area. You can ask at your local hardware store or ask a local contractor what the finished price per square foot is running for a conventional house in the neighborhood you plan to build in. That is what it will cost to finish the domes (if you do no labor yourselves), because everything in the interior is the same whether it is a conventional box house or a round house: foundation, plumbing, electrical, second floor joists, framing, lighting fixtures, bath room fixtures, kitchen appliances, flooring, kitchen cabinets, windows and doors, etc. To learn more click on Finished Cost.

Ai thinks the only big bargain you will get is our dome building kit, which costs about one third to one half less than other building kits or materials to build the exterior walls and roof of a conventional house, wooden dome or sprayed concrete dome. And with the American Ingenuity Dome you end up with a super-energy efficient, super-strong, low exterior maintenance home.

In Ai's Planning Kit is a 60 page Stock Floor Plan Booklet. On the plans is square footage by floor and  room and Ai even draws in to-scale furniture. Because the dome shape makes designing difficult, look in the back of the booklet for the to-scale ruler (on tan paper). Cut this ruler out and use it to measure the length and width of the rooms and compare those room dimensions to the rooms you currently live in. You know whether you want the rooms to be larger or smaller. This will help you figure out what size dome will fit your needs. The scale is 1/10" equals one foot.
