With the increasing pollution and population explosion in the world, people are literally looking for new ways to build in an eco-friendly style. These new bunker type homes are called earthbag homes. What is unique about earthbag homes is that walls and ceilings are made of bags earth, literally. Khalili was familiar with Middle Eastern architecture and the use of adobe bricks in building these forms, so it was natural for him to imagine building in this way.
Second, the home utilizes EcoBeams, a system of building that replaces brick-and-mortar with sandbags. The system is reported to be just as strong as a brick system and uses less timber than traditional construction. As different and more diverse methods of house building began to develop, the use of sandbags developed also. This development is the result of learning from tried and tested procedures.
The Efficient Earthbag Home
You can always revise an earthbag house but start a well-thought-out plan before building. The best place for constructing an earthbag house is warm, dry climates. The rule of thumb is to build a thermal mass structure for warmer temperatures and an insulated structure for cooler climates.
The earthbag building method is similar to masonry work, as the bags are staggered. You will need to plan everything out before building, including framing doors and windows. Through building the pizza oven we learned that our ideal mixture was 75% sand to 25% red dirt. We chose to build with Earthbags rather than cob because of the high cost of straw on the island. The next step was to find landowners willing to let us build the first earthbag dome on the island of Oahu.
How thick are earthbag walls?
But even though I was going to have more cash in hand, it wasn’t going to be enough to purchase both land and build a house. Again, you don’t have to build the same exact home. You’ll just have to adjust this tutorial to suit your design. The site also says that it has traditional walls inside of it. It has some rounded areas and a rectangular area as well.
Owen Geiger over at Earthbag House Plans has been busy. He has posted the preliminary designs for about 77 plans for earthbag homes available on his newest website. Then they were layered with plaster in order to create the exterior walls.

My earthbag house plans site has about 130 plans. Instead of filling the bags with adobe soil, I have used crushed volcanic rock. This creates a very well insulated wall that will never rot or be damaged by moisture. As a covering for the earthbags I used papercrete . This worked to seal the bags from the sun and the weather, without necessarily creating a vapor barrier...the walls remain breathable.
Jay Eisenberg / InsteadingWe added terraces to the roofs, filled them with soil, and planted native plants on them. Jay Eisenberg / InsteadingWe used fan bags to create the support for the archways. Jay Eisenberg / InsteadingWe decided to sink the house two feet into the ground. This was so we could use dirt from the site rather than having to source as much offsite.
The structure can be rectangle, square, round, ellipse, or even triangular. Always use the best building practices when shaping your earthbag house. An earthbag house costs $7 to $15 per square foot. There are many variables, including doors, windows, roof, and fill expenses. You can also build nooks, sitting areas, and couches out of earthbags integrated into the structure or you can inlay all sorts of shelving and storage into the walls. You can even build a fireplace into the interior, creating a seamless look and feel.
We are more than happy to help you find a plan or talk though a potential floor plan customization. Modern earthbag homes are made of eco -friendly products and this is the reason they don't tend to leave a small carbon footprint. They actually protect the residents from a number of natural weather conditions. All in all, these alternative houses are sure worth a try.
The last step to building an earthbag house is to install the electrical and plumbing fixtures, cabinets, shelves, etc. The finishing touches are what makes a house a home, and in this case, Geiger and his team did a fantastic job. After the roofing is in place, doors and windows are added to their frames and the exterior of the building is covered in concrete. This concrete plaster is placed in layers, first in the wedges between each row of bags, then as subsequent layers until the exterior is smooth.
Let’s say you are someone that is really concerned about your safety and the future. Then you might really want to consider building an earthbag house. Earthbag homes are a blessing in the modern day polluted world. They have perfect insulation due to the sandbag covering.
Use partially filled bags to fill gaps in the wall, next to doors and windows. A 6×12 foot wall takes an average of 288 earthbags, so you will need to fill hundreds, if not thousands, of bags. Walls are heavy and dense – Earthbag walls do not allow easy plumbing and electricity. You may want to consider a different construction method for interior walls. FieldstudyoftheworldOne of the most popular structures is the earthbag dome. The dome is a circular dwelling with a cone on top.
To the contrary, these simple materials create solid and virtually impregnable walls, which are incredibly resistant to bad weather conditions including wind and rain. The idea of earth bags was developed by an Iranian architect Nader Khalili who worked in the countryside in his nation. He used to teach people how to make adobe homes and this is when he developed the idea of modern day earthbag homes. He used sandbags ad stacked them using barbwire.
Polypropylene bags that are waterproof and fireproof. These rugged bags can endure also endure heat, wind, and cold. Luyunda Mpahlwa has said that he plans on using the prize money- $100,000- to build more of these homes, and to send underprivileged students to architecture school. Tamp down each layer of bags to prevent settling and to ensure each layer is level. Earthbag buildings have even been shown to withstand earthquakes, and as such are being used around the world as emergency shelters and to rebuild homes in disaster-stricken areas. The materials also make the home naturally fire-resistant and able to withstand extreme damp and dry climates equally well.
