Adobe Mud: Building With Earth

Simone Swan and her students at the Adobe Alliance are building with earth in the southwestern United States using adobe mud and traditional North African construction techniques.

| June/July 2009

The allure of elegant earthen architecture can be life-changing. At least that was the case for urbane New Yorker Simone Swan, who in the 1970s became fascinated with the ideas and designs of renowned Egyptian architect Hassan Fathy. Then the 40-something executive head of the Houston-based Menil Foundation, Swan moved to Cairo to study with Fathy. She became his most passionate advocate, and transplanted his adobe mud building techniques to the Southwestern United States.

Fathy’s quest was to provide comfortable and affordable housing for ordinary Egyptians. In pursuing that goal, he revived the traditional practice of building domes and vaults from sun-dried earth blocks, or adobes. By emulating ancient construction techniques and literally using the earth beneath his feet, Fathy designed beautiful, climate-appropriate buildings in the treeless Egyptian landscape. The harmonious proportions and intricate detailing transformed earth-block structures into simple yet sublime architecture.

The secrets of building with earth — most especially of Near Eastern and North African domed, arched, and vaulted architecture — had nearly been lost to history, but Fathy managed to locate builders who had not lost the skill of constructing Nubian catenary vaults that do not require wooden form work to support the construction. Fathy’s designs integrated natural cooling strategies, and he applied his art to homes, schools, and community buildings, including mosques and marketplaces. His designs were used throughout entire towns, such as Baris and New Gourna in Egypt.

After Fathy’s death in 1989, Simone Swan created a unique home and teaching center in Presidio, Texas, to demonstrate and showcase his building techniques. Adapting architectural ideas developed along the Nile River, Swan began creating a desert compound where adobe was also traditional — in the Big Bend country where the Rio Grande River separates the United States and Mexico.

The adobe tradition in the Southwest requires beams, or vigas, to support a flat roof. But the big trees along the Rio Grande have long since been harvested, so any timber used in construction has to be imported. Swan used her new building to demonstrate the benefits of Nubian vaults, which do not depend on a wooden structure. The adobe brick material is laid in a mud mortar, from the foundation to the top of the arch. The material performs the functions of wall, ceiling, structure, and body of the home.

Summertime in the Chihuahuan Desert sees temperatures consistently rise above 100 degrees Fahrenheit — thus cooling strategies are key to comfort. Ventilation near the top of the tall vault form allows hot air to escape, displaced by cooler air drawn in from the north side of the building. Fathy understood that building orientation and ornament could reduce heat gain by creating shade at the hottest times of the day. He was a master of form and function, designing architecturally beautiful openings to capture cooling breezes, and directing the air currents through the interior to flush out the warm air. The properties of the adobe building itself — the thermal mass and permeability of earth — moderate the wide temperature swings of the desert.

I would be interested in knowing if the adobe house was able to be adapted to the tropical Haiti.

I actually live in Klagenfurt, Austria but have joined forces with Marcin Jakubowski at Factor e Farm in Missouri to build a wonderful structure right here on the farm. I had taken an earth brick building course at the University of Kassel, Germany under the direction of Prof. Gernot Minke (the Pope of earth brick building). The actual trainer for the course was Dittmar Hecken, a former student of Prof. Minke. I was able to convince him to come out to Factor e Farm and run this workshop for us at the end of September. Below is a short description and invitation to this workshop. I hope you will be able to include this invitation on your blog and/or in the next newsletter you send out to your friends and members, it would be a tremendous help to us. Thanks in advance for your support! Kind regards, Inga - The Village Elder Ingeburg (Inga) von Boehm-Bezing ============================================================ Compressed Earth Block (CEB) Vault Home - Immersion Workshop When: End of September, 2009 - 5 or 10 day workshop options Where: Factor e Farm, Kansas City Area, Missouri, USA More information: In this immersion workshop, you will be building a beautiful vault-roof structure with a living roof and solar design. We are using local soil and roof from this same soil, and aim to complete one structure. Learn the techniques for this building, and if you are curious, you have a rare chance to learn about building the brick press and tractor themselves. We are using equipment that we designed, built, and open-sourced. We are developing open source technology - because it's good for the world. Do you want to live right but you are cash-poor? We are building the tools and techniques that can help you. Join us. Marcin Jakubowski, Ph.D. Open Source Ecology opensourceecology at gmail dot com Skype: marcin_ose

Thanks for the article on the adobe home. I have been interested in this type of building since 1975 while in graduate school (city planning) at Howard U. I have a ministry in Haiti and I want to know if this type of housing can be adapted to the tropics? We are a 501(C)3 nonprofit and I would like to develop a proposal to build a demonstration project with this type of structure for the poor in a rural area of Haiti. I included Farthy's work in my doctoral dissertation, so I am extremely interested in the possibility of constructing a building of this nature. Please let me know the possibilities of tropical adaptation, etc. I can work in partnership with the GOC University in Haiti. The president and founder, Dr. Fritz Olivier is an architect and a board member of this organization. Thanks for your reply a.s.a.p.
