Instructables
Ever wonder how to build a simple home for very little money, without going into debt? The key is to use low-cost, locally available natural materials such earth, small diameter wood and straw to keep expenses to a minimum. The real fun is incorporating all of these methods into an optimum, comfortable, affordable home.

Our earthbag projects have confirmed what I’ve known for a long time – that building at $10/sq.ft. (materials only) or thereabouts is possible. Other aspects of earthbag building -- strength, durability, sustainability, etc. -- are all important. But perhaps the most important point is affordability, because building at $10/sq. ft. makes housing affordable to virtually everyone on the planet. The last page of this Instructable includes a list of $10/sq. ft. projects built by others.

A big reason for the growing popularity of earthbag building is its low cost. You can build shelters for under $1,000. For $1,000-$5,000 you could have a nice, small home that would outlast most conventional wood-framed houses, and be quieter, non-toxic and more comfortable.

Are you on an extremely tight budget? (Ha, who isn’t nowadays.) Then I suggest building small using local natural materials, building in stages and adding on as you can afford it. For instance, build one roundhouse and live in it until you’ve saved enough to build another. You could join the roundhouses with arched or gabled covered walkways, vine covered pergolas, enclosed passageways or additions, or just leave them free standing. Extending rectilinear structures (adding one room at a time) would be even easier. Building a little at a time like this requires planning ahead for future doorways and other considerations, but it enables you to build debt free.

There are some village areas in the Phuket area which are reminiscent of cheap housing, although definitely not as well built as some of these. If these houses are for sale or at least the techniques of how they were built are shared, these people might get a good chance at a better and cleaner standard of living I think!

Good, common low cost housing methods in Thailand include recycled wood, CEBs, bamboo, thatch and adobes. A family built a small but nice adobe home near Khon Kaen for $100. My girlfriend saw it on TV and called me to come watch. Keep looking around and you'll find projects like this.

Frost lines change sometimes by city or smaller

All US States have residential zone structure requirement changes even down to city level, but at least by county

You have to have licensed contractors for every stage of building and approval everywhere else you can be legally made to stop or even demolish construction. At the very end every stage needs a licencor. Even if you're rural and finish the structure, contractor records are referenced by anyone who wants to research you or your property, and if it's a blank you can be forced to destruct.

These are the things the 'green' type blog posts on escaping society tend to totally ignore..

in texas there is no restrictions if building is under 1000s and on owned property.

There are lots of places with lots of exceptions. Read our blog post Counties with Few or No Building Codes.
Owen Geiger (author)  0m1kr0n2 months ago

There are places in the US with few or no codes. There's even a book you can buy that lists them. Everything is explained in this blog post called Counties With Few or No Building Codes:

http://www.naturalbuildingblog.com/counties-with-f...

In most places you can actually build a structure with ANY foundation and design as long as it has no electrical or plumbing and is around 120sqft or less..

The trailer type houses are a DOT problem and once you get them legalized they are considered RVs. Which in best case scenario from the codes I've came across for different state, are only allowed temporarily and on a time-limit bases where there is a perminant structure being constructed and requires an additional permit that costs, unless you go through a commercial based application for recreational zoning the deeded lot.

I've yet to come across any city or county that has no codes and I've spanned the country.

I forgot to add in my original comment: Your contractors licenses are audited by a final inspector in most places and even if they are all legit it's super easy to fail.

Just to add: I'm no expert by no means, I'm a owner/builder who has dug into city and county laws with the help of some agents and attorneys in various states. I'm interested in what others know on the subject and love to be told I'm wrong with explanation.

Also, I'm an engineer but not licensed to build. I may be looking in to getting the licenses to do a complete home build on my own. I know I won't be able to do electrical though because you need to be licensed for that which takes a four-year apprenticeship and you have to basically beg electricians to do do that and they are typically grumpy.. You would be amazed what you can do by just learning foundation design and concrete work though(there is only like one quality book in existence on the subject).

Put a layer of gravel under the floor with a perforated vent pipe that vents through the soffit or roof, then plastic sheeting on top then your floor. Talk to local builders for details if necessary.

In some places the building code involves a gap between the foundation and the ground in case of radon gas. How would you solve this?

Sounds like a great way to build a home, however in Indiana, USA we have to deal with building codes and permits.
Owen Geiger (author)  wmlaveck1 year ago
Contact Structure1.com. They can supply plans or tweak my plans at Earthbag House Plans to meet code.

please can you advise,,Im in the process of selling my place,ready to buy a piece of land but the money to build a regular house is not there,in other words,the budget is very tight,I want to build some thing around the 1200 sqft including in it two porches and no garage,,,I would like to either build or have some one build one of your earth bag houses,but there may be a problem with the county codes etc,,please advise,how can I have one of your houses build.,thanks
Owen Geiger (author)  cking343 months ago

It all depends on your code situation. Rural areas with minimal codes are by far the best, lowest cost places to build with alternative materials such as earthbags.

Owen Geiger (author)  wmlaveck3 months ago

Yes. We always recommend moving to rural areas with few or no codes. You can build at 1/10th the cost this way.

Hi Owen! I have LOVED the idea of an earthbag house for awhile now! My small family of 3 is in desperate need of a place of our own. We're sharing a bedroom in a family member's house... 3 of us crammed in one hot tiny 10x10 room is getting OLD. I would like to know if these types of homes stand up to hurricanes ok? Everyone is telling us to get a trailer, but they're trashy and you *have* to evacuate when there's a hurricane (I live in Florida). I was thinking of purchasing a lot and eventually building one of these homes on that lot. But I don't know how I can convince anyone that this is worth the time and money, as much as I think it is. Have any helpful advice or links? Thanks!

Owen Geiger (author)  histechnoangel3 months ago

Earthbag structures can definitely withstand hurricanes if they're built correctly. The problem is the codes in Florida (and California, etc.) are super strict and it's hard to get earthbag houses approved unless you spend a lot of money on engineering and extra steel and concrete. We always recommend moving to rural areas with few or no codes. You can build at 1/10th the cost this way.

I like that type of building , but the local buildings authority told me that there is no way to build that here in Spain... Any advice on this?

Zdaddy2 years ago
The problem I am facing is where to build. I've seen countless of very cool and interesting alternative home building methods. So I know I am capable of doing it and I'm not ever going to be out of ideas.

I bought 0.25acres of land in the mountains about 45 mins away...only to find out there is no where in my state that you can get away with this kind of living. Luckily I was able to back out of the deal due to the seller not disclosing certain things to me as the buyer, I got my money back. That was a close call!

There is a case right now in San Diego of a man that is being evicted from his land even though he is paid in full and paid his taxes for over 20 years, the new neighbors just dont like that he lives in a mud hut on his acreage. It devalues their home. The city is backing up the neighbors.

I've been running this through my mind for years now and unless I leave the state or build in secret away from prying eyes (which wont ever happen, too much risk and at least in CA there are eyes everyhwere) or buy property and submit building permits (ha! Good luck!) then I can't build my own sand bag home. All californians are doomed to live strapped down to rent (100% interest home) or a mortgage which makes you a slave to the bank.

What we really need is an instructable on how you can make it possible to build homes like these.

We have a blog post on Counties with Few or No Building Codes. It's our most popular topic, so obviously people are interested in learning more about this.
http://earthbagbuilding.wordpress.com/2010/01/24/counties-with-few-or-no-building-codes/

The blog post lists some of the best areas and some general advice. Be sure to read the comments. In general, there are lots of areas in the western US where you can build with earthbags, and other areas too.

California is probably the most difficult state to deal with. Any highly populated state is difficult. We always suggest building in rural areas with few or no codes. I don't know how else to explain it. It's more of a personal journey one has to go through. Everyone's opinion about climate, geography, town size, etc. is different. You'll have to figure out what works for you.
Where did this blog/url go in your above response , Owen? I copied and pasted , and looks like it has been moved. Did a search , found it in older posts and still cannot open. Would love to read up on this and see where may be the best place to go! Thanks!
Thank you for the links Owen! You seem passionate about this, its an inspiration. I wont give up! :)
Owen Geiger (author)  Zdaddy2 years ago
The other alternative is hiring an engineer to stamp your plans. The only engineer at this time is Precision Structural Engineering, Inc. Their engineer stamp will enable you to build virtually anywhere. www.structure1.com

However, be forewarned. Code approved structures will cost significantly more than ordinary earthbag houses. Way more. About several times the cost.
gsolano1 year ago
Thanks. I just can't imagine how it could cost more. We'd like to build the Torus. There are 6 of us. What would be the rough cost of just the building, not interior, cabinets, etc.
And how long would it take to build something of that size with 7 workers, for instance?
Thanks again.

Thank you so much for this fantastic info. I really want to build an earth bag home. I'm confused by the price per sq foot. I've seen many posts that say that it is much more affordable than a traditional home but when I've called some builders, they've told me they cost the same or more. And that's with only paying the builder as a consultant and all volunteer labor. I was so excited that we could build and be somewhat debt free and now I'm depressed. :( Please advise.
p.s. I realize that you could spend $100 on a doorknob or $5. I am really talking about the basic home; walls, roof, basic doors, windows, earth floor. I can do cabinets and interior over time. Thank you for your help!
Owen Geiger (author)  gsolano1 year ago
Why would you believe a builder who says the cost would be the same if you use all volunteer labor? He's obviously going to pocket the difference! Come on! And who said you need a builder (contractor)? Why not hire a carpenter guy who's low on work? Make sure he's reliable, of course. Don't advance them any money. Take out the building permit yourself so you are the owner builder. If he screws up, let him go and get someone else.

You don't need GPS. That's the ultra modern, high end equivalent of transits. And besides, it's probably best to pay professional surveyors to ensure it's done correctly.

Hi Owen! I need help.My family and i want to build a earthbag house in Serbia.Please tell me how to set the water heater to this type of house?Please answer me on tanjat39@gmail.com
Thank you very much!
sasham ttaichi2 years ago
Skip earth bags, and come to Vojvodina (area of Serbia) where there are countless superior earthen homes, beautifully designed and skilfully built.
Owen Geiger (author)  sasham2 years ago
How do you know they're superior? Have you carefully studied earthbag building and visited lots of earthbag projects? How many hours have you spent on research?

That said, you can learn a lot from traditional building methods. I like to learn from the old ways and apply a bit of modern ingenuity to make something even better.

Study lots of houses and choose what looks best to you. It's really a subjective thing that no one else can decide for you.
I love earthen houses! I have been fortunate enough to live in one for a short period of time, and I love the way they stay warm in the winter and cool in the summer. The house I stayed in was heated by a wood stove, but the radiant floor heat would be heavenly!

BTW While you're out in the country looking at land, check with feed stores or ranchers to see about getting free bags to put the dirt in. Nowadays most livestock feed comes in polypropylene bags and they usually don't recycle them, so you'd be saving them from winding up in a dump and saving money as well....
czflgator2 years ago
If you can purchase land in agricultural zoning, check the codes for building barns. Usually you can have an "office" in a barn, plus a bathroom. In my area, you can have a bathroom and office area, but not a full kitchen. Of course, once the permits are pulled, the structure built and signed off on, who's going to know what modifications you make?

Hello Mr. Geiger,
I am 16 years old, and "green housing" really interests me. I have always wanted to be a Civil/Electical engineer, but I was wondering what college degrees you would recommend to get into the field of this kind of housing. It seems like there is a lot of eco-science involved, so I just wanted to get your opinion.
Thanks!
Owen Geiger (author)  wazupwiop3 years ago
Construction is a huge field. There are architects, engineers, project managers, expediters, cost estimators, foremen, supervisors, designers, surveyors, city planners, etc. There are also lots of business opportunities in producing building materials, software, etc. So the first step is to identify your natural skills, talents and interests and then align those with promising job prospects. For instance, the big money is typically in commercial work, but maybe you're not interested in 'green skyscrapers' and urban development. Maybe you'd like a more academic route in materials science. Or you could get good at a few related skills.

Plan carefully because the housing market looks like it's on a long downward spiral due to a poor economy and the collapse of the housing bubble. Also think about what is most in demand and what jobs can't be offshored to lower cost workers. Will your dream job even exist in 20 years? Or will that field be automated? Lots of considerations.
I live in Ohio, and the state is asking for people to pursue engineering of any kind. They need electrical engineers at the car manufacturing plants, and they need civil engineers because the state has plans to expand cities and roads.

Another reason why I expect engineering to grow is that the world's population is growing. Two weeks ago, we just passed 7 billion in population. In 50 years, 8 billion people will live on earth. This is a big issue in larger cities like New York, where they cannot expand horizontally, but only vertically. New York needs Civil Engineers to design their building and etc. While I don't necessarily want to design sky scrapers, I still think my job will be around in 50 years or so.

I see the possibilities of green housing in the Plain States. States like Ohio, Iowa, and Nebraska face cold winters, but we also have really large plains. I could see these houses built out in the rural areas.

Thanks!
