Adobe T-bricks is just one of many ultra low cost natural building methods.


I love the great ideas coming out of the tiny house movement, and it’s great to see growing interest in this area. One topic that’s not talked about often enough in my opinion is do-it-yourself, super cheap tiny/small houses made of natural materials such as earthbags, straw bales, adobe, compressed earth blocks, recycled wood and so on. The cost difference can be HUGE.

First of all, I realize everyone’s situation is different. If you absolutely need to be mobile or live in the city then building a tiny house on wheels is a good option. But for many others a dirt cheap $2,000 house on rural land with minimal building codes is an even better option. Nowadays you can get decent Internet, phone and electric most anywhere. You don’t have to live in the middle of nowhere at the end of a 100 mile dirt road that turns to sinking clay when it rains, or live deep in the wilderness on a mountaintop. There are still quite a few minimum code areas that allow owner-builders to build sustainable homes with alternative materials.

The Natural Building Blog is loaded with free information about all types of low tech/dirt cheap building methods. This article on How to Build Dirt Cheap Houses is a good overview.

Just to be clear, $2,000 is an approximate cost for the main shell of a house – walls, recycled windows, doors and roof for a small home of a few hundred square feet. Of course you could spend way more or possibly less. The main factors are building codes, the materials you use and how much labor you do yourself. You can save tons of money by using locally available materials such as wood poles from a forest, slab wood siding, salvaged wood from old buildings, and hardware and fasteners from yard sales or Craigslist.

Here are a few examples of super low cost tiny houses built with natural materials:
Adobe T-bricks (see photo above): This option was covered in yesterday’s blog post. The main cost for this type of home is the roof. But again, you could use salvaged lumber or wood poles to save money.
Earthbag roundhouses: This is our $2,000 guesthouse that you’ll see in my various books, DVD and articles. We later replaced the thatch with more durable micro concrete roofing tiles that can last 25-30 years. In this case the cost included electric, plumbing and a few extras such as colorful glass block in the bathroom.
– $300 Houses: My $300 Earthbag House was the 14th place winner in the $300 House Challenge. Building for $300 is only feasible if you do everything yourself, barter, use all salvaged/recycled materials, etc. This is how people live in slums, and this design is an attempt to meet the needs of slum dwellers. In most cases, westerners would likely buy many of the materials and so the house would likely cost around $2,000 for the basic shell.
Simple DIY strawbale houses: Stephen and Nena MacDonald’s post and beam strawbale house in Gila, New Mexico was built in 1988-1989. The initial shell was $5/sq. ft. and the finished cost was between $7-$8/sq. ft. This was back in the 1980’s so naturally the cost would be a higher now.
Strawbale shelters: Matts Myhrman pioneered the construction of tiny strawbale shelters, and since then others have utilized these ultra low cost building ideas. This video shows how unskilled workers can build a simple shelter in a few hours. Authors Matts Myhrman and S.O. McDonald have generously donated their classic volume Build it With Bales, Version Two that can now be freely downloaded at the following link:

Summary: Factory-built ready to live in tiny houses are going for about $70,000 and up. On top of that you might have to pay for space to park your tiny house. Even DIY tiny houses are around $30,000 – $50,000. So you’re still talking about quite a bit of money. That’s why I’ve always been fascinated with natural building and simple living, and have spent the last 20 years promoting these efforts.

$2,000 DIY Tiny Houses — 9 Comments

  1. I live in the city and the thought of rural living is very foreign to me. However I must say just looking at your tiny house and a rural location away from the noises and congestion of the big city seems welcoming right now maybe city boy might be converting. Good job for only two grand.

    • A sustainable rural location (garden, water, etc.) could save your life in depressions/economic crashes like it looks we’re headed into.

  2. if a person has to follow codes for building the envelope/shell, and not be able to use repurposed for that.

    then build an open floorplan with few stationary walls.

    after your home is complete, then you can build partitions and sliding walls of repurposed items.

    and when you ‘want to remodel/or just move things around, you don’t have to tear out walls! you can just move them around to shift your space.

    we are always shaping our shift.
    and
    we are always shifting our shape.

    • Sounds awesome! I’ve only lived in conventional homes, never heard of being able to move things around after the fact! :D

    • Around 50% of the homes in the world are made with natural materials. Most are made with earth in developing countries. Some of these homes are hundreds of years old. The natural building movement is trying to build on this track record and create even stronger, better designs.

  3. I was planning on using Habitat for Humanity for supplies. it’s a recycled/donated place for building supplies/for inside as well as outside of a house.. Which plan/house building type takes the shortest time to build?? I rent where I currently live, the landlord never fixes anything, home is falling apart. You have to pay him if you want him to fix anything. Or do it yourself. He uses druggies to fix/build anything. Our back porch had to be rebuilt a few yrs back, (3 yrs at the most, I believe). It already needs to be rebuilt, (been needing to 2 yrs after it was built). Shotty work, exposed/half hammered in nails, no protective anything applied. Just slapped together. Their’s your porch.. Their are alot of soft spots in the floor, various spots, but mostly bathrooms. The driveway is almost eroded away, my boyfriend already knows he will have to fix it, since the landlord won’t.. This is why I been wanting to get out soon as I can..

    • It’s difficult to give detailed advice since everyone has their own preferences, live in different climates, codes, etc. It also depends how long you plan to stay there. Two quick options: 1. recycled wood framing, 2. for longer term I would suggest post and beam straw bales on gravel bag foundation.
