International Dome Houses

The Japanese know a thing or two about living in small spaces. Additionally, Japanese designers and architects also have to know a thing or two about how to design homes for a country with high land prices, strict building codes and numerous earthquakes. These futuristic prefab houses from the International Dome House Company are built from segmented slices made of expanded polystyrene that claim to be superior to wood, iron and concrete.

Japanese Dome House Website

The company is located in Japan, but the dome segments are made in their factory in South Korea. Several small “villages” of various sizes of the dome houses have been built in Japan, where the design has been approved by the Japanese Ministry of Land and Transport. This building system can also be adapted for small businesses, storage areas or bathhouses.

However, the website says that this type of construction is “semi-permanent”. I asked Dome House International what they meant by that statement and the company said that their product’s structural material, expanded polystyrene, lasts semi-permanently because it could be affected by UV light, chemicals or heat. The material is covered with a special coating that protects it from damage. The Dome Houses have not been experimented on, but Dome House International claims that they can last for 300 years. They also said that there has been several cases where expanded polystyrene has been used for decades, and when the buildings were renovated, the material had not been damaged at all.

The Dome House can be built by assembling separate dome pieces. Each dome piece weighs about 175 pounds. It will take three to four people about a week to complete a Dome House. The basic model is about 22 feet in diameter, but separate domes can be added together to make larger buildings. Since expanded polystyrene is made only from carbon and hydrogen, casting of expanded polystyrene is extremely clean. Construction of the Dome House does not produce any waste, nor does it involve any deforestation.

The Dome Houses have beautiful, simple interiors with lots of light. They have no corners, so each dome is open for interpretation and interior design. The Dome House is simple, since it is a prefabricated building with a small number of parts. Because the construction of the Dome House requires only minimal manpower and a very short period of time, it is possible to reduce the substantial amount of labor costs. Prices on the U.S. website will be available soon. However, the prices on the Japanese website for the basic dome are about 3 million yen or about $33,000, not including shipping. The prices and specifications for domes in other countries will be different.

Benefits of the International Dome House

  • Ultra-thermal insulating
  • Semi-permanent durability
  • Wind resistant
  • Earthquake resistant
  • Short assembly time
  • Low cost
  • Good for people with chemical sensitivities

  1. Some of the criticisms of tiny houses on wheels could be resolved with an adapted International Dome House. The current plans are far too large to be mobile, but the challenges of insulation, structural integrity, wind resistance, and stability are resolved in this design, as well as weight and the aerodynamics of towing our houses to the next “neighborhood”.

    The current models are,at their smallest, over 25′ wide and 13′ high. We would need a width and length that would be trailer-legal.

  2. My goodness, these are cute. They look to me like a cross between hobbit houses and a village on the moon. I would definitely live in one!

  3. They look like a direct lift from Outpost Alpha (Yahoo) created by George Berz in Fresno about 2005. He created a yahoo site but has not replied to posts there since. Here is a link.

    George like others had gotten his information from Monolithic Domes of Texas. To my knowledge, he had never actually built one and was looking for partners to build a community in texas.
    This is when the tiny house community began to show signs of life on the net. As far as International Domes being inovative, they are OK at copying because the design was done by George more than five years ago.
    The idea of living in expanded poly styrene has me thinking about the cancer developed in workers in factories where this is made and then again the CFC issue.

    • Just seeing this site and posts. The big difference between International and Monolithic in Texas is Monolithic Domes out of TX are now 3-5 times higher than they were 3-5 years ago. So a MD is now (2016) $60,000-$80,000 for 22′ dia -27′ dia domes up from $15,000-$30,000 (in 2011/12). The $60K-$80K price tag doesn’t include finish out. So by the time a MD house is fully finished you’re looking at $90,000 – $130,000. Also MDs take longer than a week to construct and requires lots of expensive and heavy equipment and tools. IDHs take about a week and 2-4 people to put together. The issue with IDHs might be current/2016 US prices and what’s the cost to ship them from Korea that will add to the cost.

      One thing I didn’t see in the videos with construction segments that are out for International Dome Houses is where are they putting the electrical and plumbing? Will IDH pass our local city/county building codes?

    • Freth, Hello! I am wondering if this is the same product. The site you cite, http://cbsstructures.com/, says “Built like a giant ice cooler, the double composite fiberglass FRP shell sandwiches a core of urethane foam and a Space Age Thermal Barrier Foil insulation for a very high energy efficient dome.”

      From the article above, “the company said that their product’s structural material, expanded polystyrene, lasts semi-permanently because it could be affected by UV light, chemicals or heat. The material is covered with a special coating that protects it from damage… Since expanded polystyrene is made only from carbon and hydrogen, casting of expanded polystyrene is extremely clean. Construction of the Dome House does not produce any waste, nor does it involve any deforestation.”

      What do you think?

  4. Not only are these homes cute – very hobbit like and fun – and I understand that they withstand hurricanes and other storms very well. The high winds just flows over them. I would think this type of building would work great in areas that are often hit by earthquakes and hurricanes and other disasters. I would think that an inexpensive version could be designed to help provide housing to the poor of the world.

  5. The photo of the living/dining with the loft, spiral staircase and divider wall, just kills me. So elegant and appealing. Curves + lines in the right places = looove

    • @ Kaleigh – Go to http://www.monolithic.com and they can tell you pricing. The are usually 2/3 the price of a comparable 2×4 wood frame home, and MUCH more energy efficient. David South of Monolithic.com has designed a way to build dome homes, and has many plans to choose from. I’ve toured a number of their domes, and they are AMAZING! you can also find the page on Facebook under “Monolithic Domes”. Hope that helps.

  7. I’ve got friends who are totally into the dome houses… Unfortunately do not have any idea going about contacting the manufacturers… Visited their website, they don’t provide landline nor mobile numbers… only e mail which would take them forever to reply… Can someone out there help?? Would appreciate very much…

    I was wondering if these domes are build for cold places like Minnesota, Minneapolis??
    Or extra humid like Washington DC?
    The shipping cost is important too. But right now we would like to invest in one unit see how we like it. Please let us know about the shipping fee and rules and regulations.
    Best, Roya

  12. Styrofoam (expanded polystyrene) is an extremely environmentally damaging material. Just because its formula has only carbons and hydrogens does not mean it can easily biodegrade. Also as it disintegrates it is toxic to wildlife.

    Reply
    • The whole idea is that you protect the foam from direct exposure to the environment so that it does not degrade at all. . . You work to prevent it from disintegration, and if you demolish it, you cart it to a recycler. . . your argument is not real cogent.

  13. I’m interested in exploring this probable business opportunity, how can I contact the dome munufacturers? Since these units seem to be ‘heat sensitive’, how do they perform in tropical climates (eg. the Caribbean or Central America)?

  14. Hello,
    I hope someone can answer a few questions for me:
    1. Is there a distributor in the U.S. ?
    2. How do you install electrical/hvac ?
    3. Are these good in cold weather/snow climates ?
    4. Do you place them on a concrete slab ?
    Thanks,
    Michelle

  15. Hello,
    I would like to know if Expanded Polystyrene Domes are available in US. If it is available in US, how hard is it to get a building permit to build this type of dome house and how much is the shipping rate. Is there any EP dome house experienced builder/contractor in here?
