Recent years have seen a flourishing of organizations that gather people with common interests participate in do-it-yourself activities

In a reaction to the digital age, creative people are finding ways to build community in the real world to share knowledge, projects, and ideas. People are looking to the Internet to find outlets for active creativity, rather than merely passive entertainment or consumption.

Cases

The Make Lounge

North London’s Make Lounge brings arts and crafts into the 21st century. One-off workshops are delivered in a branded “drop-in” environment, attracting those looking to dabble in activities such as millinery, jewelery making, or knitting.

The School of Life

Located close to some of London’s top universities, The School of Life makes adult education accessible and cool. Opened in September 2008, the space features a shop that sells books, art, courses, vacation packages, and consultancy to those seeking intellectual adventure. Beneath the shop is an underground classroom that hosts regular courses across five central themes - work, play, family, politics and love.





Maker Fair

Dubbed “Woodstock for inventors,” Maker Fair is a two-day event for people who love to make things themselves. Everything from arts and crafts to engineering and science, sustainable design, food, and music are represented. The event is no small job for organizers Make Magazine and Crafts Magazine: the last Maker Fair attracted 65,000 people.

Trend Impact
Although the Internet may provide us with instant, free information, we still thrive on real-world human interactions. Creative people are going online to connect people with common offline interests.

New houses in Sweden are primarily built on slabs, partly because its expedient, but also because its naturally the best way to have in floor radiant heating. In a cold climate this is the only way to use a slab otherwise your slab will feel cold and uncomfortable. But a slab in a cold climate must be insulated from the elements or it will throw heat out its edges. There are typically two strategies to isolate your slab from the cold.

Because of this history of military and flood control, the use of sandbags has generally been associated with the construction of temporary structures or barriers. Using sandbags to actually build houses or permanent structures has been a relatively recent innovation.

It was an Iranian-born architect named Nader Khalili who has popularized the notion of building permanent structures with bags filled with earthen materials. Actually his first concept was to fill the bags with moon dust! Attending a 1984 NASA symposium for brainstorming ways to build shelters on the moon, Khalili coupled the old sandbag idea with the ancient adobe dome and arch construction methods from his homeland in the Middle East. He realized that bags filled with lunar “dirt” could be stacked into domes or vaults to provide shelter.

Khalili came up with a further refinement on this building concept on Earth: for a more permanent, shock-resistant structure, why not place strands of barbed wire between the courses of bags, thus unifying the shell into a more monolithic structure?

At first Khalili was filling his experimental bags with desert sand, but then he evolved his idea of “superadobe,” where bags or long tubes of polypropylene bag material would be filled with a moistened adobe soil that would dry into large adobe blocks. In this case the original bag material was merely the initial form and would not necessarily be an integral part of the eventual structure.

Soon after these first experiments, Khalili began publicizing his work through newspaper and magazine articles and conducting workshops and seminars on the techniques that he was perfecting. Many people who read about his work, visited his compound in Hesperia, California, or studied with him there, decided to go ahead with their own experiments with his ideas.

Among these “early adopters” were Joe Kennedy, Paulina Wojciechowska, Kaki Hunter and Doni Kiffmeyer, Akio Inoue, and Kelly Hart. I believe that it was Joe Kennedy who coined the more general term “earthbag” to suggest that the bag could contain a variety of earthen materials.

Paulina Wojciechowska was the first to write an entire book on the topic of earthbag building: Building with Earth: A Guide to Flexible-Form Earthbag Construction was published in 2001. This featured some of her early experiments done at Khalili’s CalEarth, along with several other case histories.

Akio Inoue, from Tenri University in Japan, has done extensive experimentation with earthbag construction, both on the campus of the University and in India and Africa where many other domes have been built for assistance programs.

Kaki Hunter and Doni Kiffmeyer (a couple) became enamored with earthbag construction after studying with Khalili, and worked on a variety of projects, both for themselves and for clients. In 2004 they wrote and got published another book, Earthbag Building: the Tools, Tricks and Techniques, based on their particular experience.

Kelly Hart (the author of this article) first began experimenting with earthbag building in 1997, after being exposed to the concept while producing his video program, A Sampler of Alternative Homes: Approaching Sustainable Architecture. He later documented his experience in actually building his own home in another program titled Building with Bags: How We Made Our Experimental Earthbag/Papercrete Home. Both of these programs are now available as DVD’s.

In the meantime, Nader Khalili was continuing the promotion of his “Superadobe” technique and eventually decided to patent the idea, which he obtained in the U. S. in 1999, using very general terms that cover using bags made of any material being filled with virtually any material, and combining these with barbed wired between the courses. While having made many public statements that this concept was his gift to humanity, he obviously wanted to capitalize on the potential economic reward.

Many of us who had been engaged in promoting earthbag building on our own were contacted by Khalili and asked to enter into contracts with him in order to continue our work. It didn’t take much research to discover that his patent could easily be disqualified because he had been publicizing his techniques through various media for at least four years before he even applied for his patent. Patent law clearly states that such publicity occurring prior to one year before the patent application would disqualify it for consideration.

So now the door is wide open for anyone to take this concept and run with it, and more people are doing so all the time, all over the world. While Khalili (and most of his students) have focused primarily on using the bags to form large adobe blocks, others have tried filling the bags with a variety of other materials, such as crushed volcanic rock, crushed coral, non-adobe soils, gravel, and rice hulls.

Earthbag building is unique among all other building technologies in that it can be either insulation or thermal mass, depending on what the bags are filled with. This is a very important distinction, because these characteristics of a wall greatly influence how comfortable, economical, and ecological any given system will be.

Safety is of prime concern with all building technologies, and much experimentation and testing has been done to establish guidelines for many ways of building. Khalili has established a relationship with the building department in Hesperia, California where CalEarth is located, an area where earthquakes are naturally a great danger. In 1993 live-load tests to simulate seismic, snow and wind loads were performed on a number of domed earthbag structures at CalEarth and these exceeded code requirements by 200%.

In 1995 dynamic and static load tests were performed on several prototypes for a planned Hesperia Museum and Nature Center to be constructed using Khalili’s Superadobe concepts with both dome and vault shapes. All of these tests exceeded ICBO and City of Hesperia requirements.

In 2006, at the request of Dr. Owen Geiger of the Geiger Research Institute of Sustainable Building, the Department of Civil and Mechanical Engineering of the U.S. Military Academy at West Point conducted several controlled and computer-monitored tests to determine the ability of polypropylene earthbags filled with sand, local soil, and rubble to withstand vertical loads. Their written report concluded that “overall, the earthbags show promise as a low cost building alternative. Very cheap, and easy to construct, they have proven durable under loads that will be seen in a single story residential home. More testing should prove the reliability and usefulness of earthbags.”

Despite the success of these tests, earthbag building concepts have yet to be incorporated into the International Residential Building Code. Obviously more enlightened acceptance of the demonstrated viability of earthbag building needs to occur!

It is difficult to know how many residences and other earthbag structures have been made at this point, probably hundreds if not thousands. Many of us have been promoting the technique for use as emergency shelters, and certainly some have been built for this reason. It is easy for folks to accept this way of building temporary shelters because it fits the historical model of sandbag use.

But many of us have also built substantial homes using earthbags, and in the process realized how truly versatile and sustainable the technique is. I wouldn’t be surprised if many of these earthbag homes are still standing long after their conventional counterparts built contemporaneously have disintegrated.

"We are a team consisting of a developer, architect, and
contractor who were getting frustrated by the dismissive response to
modern design by clients and real estate professionals in our area,
so we decided to do our own thing with incredibly positive results.

We couldn't understand why people would seek out the latest design
and technology in cars, electronics, etc., but new builder/spec. home
construction seemed to be stuck in the year 1900. How many people
would go to a store for a new computer and happily walk out with a
univac the size of a refrigerator that only did addition and
subtraction? Yet people were making a similar decision every day with
a new home. We just didn't get it.

So, we design and build homes that respond and complement modern
life, are extremely efficient in terms of energy, space, livability,
constructability, and are affordable."

Here is part of a letter sent out by his family to former students:

“The flames that ignited him in life and the quest that brought each of you to Cal-Earth to learn from him have touched all of us and led us on this path….the right path……. for arts, humanity and the environment. His work and words have inspired us and his spirit is powerfully alive in every work and word, building and echo that your enthusiastic and loving hands have helped to create for this world.

His soul imbues every grain of sand and every memory contained in Cal-Earth, which expresses so much of his personal life of the last 17 years. And your works, like seeds have been growing and flourishing in every corner of the world…”

Born as an Iranian, Nader lived most of his life in the United States, gaining an architectural degree. He worked on the design of high-rise buildings and taught architecture in Southern California. In 1991 he founded Cal-Earth (the California Institute of Earth Art and Architecture) based in the desert region of Hesperia , California. From this center, he taught classes and workshops on the use of both bricks and bags to fashion domes, arches, vaults, and irregular shapes. These forms sprang from his early exposure to Middle Eastern architecture.

The earthbag concept evolved from attending a 1984 NASA symposium for brainstorming ways to build shelters on the moon. He realized that bags filled with lunar “dirt” could be stacked into domes or vaults to provide shelter. This concept was later refined to include stretching barbed wire between the courses of bags to help stabilize the structure. Nader never referred to this building technique as earthbag building; he preferred to call it “Super Adobe,” referring to the fact that he generally filled the bags (or long tubes) with an adobe soil mix.

In 1999 Nader was issued a U.S. Patent for his Super Adobe technique and he subsequently tried to require contractual arrangements for its use. At this point, however, he had been publicizing the idea for so long it was not an enforcable patent, and few would comply with his request.

This fact points to the complex nature of Nader’s personality. He truly loved humanity and the arts, and was an eloquent and passionate speaker. He often said that his ideas were a gift to humanity and he hoped they would provide shelter for the poor and disadvantaged. At the same time, he wanted to control the economic potential of his invention, and he pursued this vigorously.

Nader was the author of several books, including Ceramic Houses and Earth Architecture: How to Build Your Own, about literally making ceramic houses, and Sidewalks on the Moon, an autobiography. He also wrote several books about the the mystic poetry of Rumi. Interestingly, he never really wrote a book about his Super Adobe invention, allowing others to take the lead in doing this.

With the passing of Nader Khalili we have come to a point where his ideas and work can truly become universal. All of us who explore the potential of the earthbag concept and expand on its possibilities can help further his vision for bettering the world. We owe a great debt to this truly inspired individual. May he rest in peace!
