inhabitat.com presented a collection of eight small “earth homes that almost anyone can afford” and half of them are built with earthbags!
La Casa Vergara’s dome shape may captivate the eye, but what’s underneath is most impressive. The Bogota home, built by architect Jose Andres Vallejo, is made from earthbags, or tubular bags stuffed with earth. Exposed timber beams and plentiful daylighting make everyday living a pleasure and the $28 per square foot price tag puts the home within many buyers’ price range.
These charming hobbit-like dwellings are prefabricated by Magic Green Homes and can be constructed in just three days. Sized at 400-square-feet, the green-roofed living spaces are easy to assemble. They require no heavy equipment to build, instead utilizing perforated flaps that are screwed and sealed together. Magic Green Homes adapt to any topography around the world.
For anyone who is interested in building their own earth home, yet doesn’t know where to start, the guidance of Cal-Earth might come in handy. The California-based group teaches others DIY methods for creating your own dwelling using sustainable and disaster-proof materials. Sandbags packed with earth, barbed wire for tension, and stabilizing materials such as cement, lime, or asphalt emulsion all come together in a comfortable home that can withstand the elements.
Orkidstudio, an organization that specializes in humanitarian design, opened up an orphanage in Nakuru, Kenya that is made entirely out of earthbags. The passive solar structure absorbs heat during the day and releases it at night, creating a comfortable space for the children and staff inside. The orphanage is clad in recycled timber and features running water sourced from an on-site rainwater collection system. Not only did the project come together to produce an inviting and efficient facility, but it was put together in only eight weeks by a team of UK architecture students.
Building low-cost, environmentally friendly homes is a sign of moving in the right direction and the Earth Home Builder makes the process amazingly efficient. Working similarly to a 3D printer, the skid-operated machine can fill bags of earth at a rate of 400 bags per hour. Given that only 30 bags can be filled at the hands of humans, the machine could revolutionize access to affordable and responsible housing. United Earth Builders, who developed the technology, are working to find non-profit partners to help bring earth homes to the masses.
One family in Mexico opted to create a multi-colored home on a budget. The rammed earth dwelling used the practice of adding pigment to the material before layering the walls from the ground up. The distinct effect adds to the temperature control qualities of the home, which is essential during the hot Mexican summers. This Ajijic house features floor-to-ceiling windows and two open terraces to take advantage of the lake views.
Chiangmai Life Construction has built the Triksa Villa in northern Thailand, a stunning structure made from part rammed earth, and part mixture of clay and concrete for the foundation. Adobe brick walls keep the space a comfortable temperature while the bamboo roof and recycled hardwood are other sustainable aspects.
In the countryside of Ghana lies this unique home made from rammed earth, recycled plastic, and fortified against the elements using natural materials. The home was constructed from student Anna Webster’s winning design through a Nka Foundation building competition. She states, “We aimed to overcome the negative associations of these materials and move away from the primitive image of building with earth by applying a modern design aesthetic.” Plastic waste is repurposed into window screens and roof materials and the sturdy rammed earth walls are covered in a cassava starch sealant to prevent exterior water damage. The home cost just $7865 to construct and serves as an example of what can be done with found materials and a little creativity.
