Adobe

Adobe is one of the oldest building materials in use. It is basically just dirt that has been moistened with water, sometimes with chopped straw or other fibers added for strength, and then allowed to dry in the desired shape. Commonly adobe is shaped into uniform blocks that can be stacked like bricks to form walls, but it can also be simply piled up over time to create a structure. The best adobe soil will have between 15% and 30% clay in it to bind the material together, with the rest being mostly sand or larger aggregate. Too much clay will shrink and crack excessively; too little will allow fragmentation. Sometimes adobe is stabilized with a small amount of cement or asphalt emulsion added to keep it intact where it will be subject to excessive weather. Adobe blocks can be formed either by pouring it into molds and allowing it to dry, or it can pressed into blocks with a hydraulic or leverage press. Adobe can also be used for floors that have resilience and beauty, colored with a thin slip of clay and polished with natural oil.

Adobe buildings that have substantial eaves to protect the walls and foundations to keep the adobe off the ground will require less maintenance than if the walls are left unprotected. Some adobe buildings have been plastered with Portland cement on the outside in an attempt to protect the adobe, but this practice has led to failures when moisture finds a way through a crack in the cement and then can't readily evaporate. When adobe is used as an exterior plaster it is either stabilized or replastered on a regular basis.

Adobe is a good thermal mass material, holding heat and cool well. It does not insulate very well, so walls made of adobe need some means of providing insulation to maintain comfort in the building. Sometimes this is accomplished by creating a double wall, with an air space, or some other insulation in between. Another approach is placing insulating materials on the outside.

The Adobe Story: A Global Treasure by Paul Graham McHenry, 2000.Most Americans associate adobe with grand haciendas in the deserts of New Mexico and Arizona. But this earthen building material is used all over the world. Here a leading adobe architect and builder surveys the use of adobe around the world, examines the state of the adobe industry today, traces the evolution of adobe in New Mexico, and offers a tour of New Mexico adobes from prehistoric Chaco Canyon to such recent buildings as the Dar Al Islam mosque and Christ in the Desert Monastery, both near Abiquiu.

Earth Architecture by Ronald Rael, 2008. Currently it is estimated that one half of the world's population, approximately three billion people on six continents, lives or works in buildings constructed of earth. Author Ronald Rael, founder of Eartharchitecture.org, provides a history of building with earth in the modern era focusing particularly on projects constructed in the last few decades that use rammed earth mud brick compressed earth cob and several other interesting techniques. Earth Architecture presents a selection of more than 40 projects that exemplify new creative uses of the oldest building material on the planet. Rael's engaging narrative addresses the misconceptions associated with earth architecture. Rael also touches on many topics that pervade both architecture and popular media today such as the ecological benefits and the politics of building with earth particularly in developing nations where earth buildings are often thought of as pre-modern or backward. With engaging discussion and more than 300 images Earth Architecture showcases the beauty and simplicity of one of humankind's most evolved and sophisticated building technologies.

The Cheap-Ass Curmudgeon's Guide to Dirt: Hand-Building with Adobe, Papercrete, Paper-Adobe, and More by Michael Van Hall, 2009. This down-loadable e-book is a somewhat whimsical guide to building with adobe in an unconventional way. What this curmudgeon advocates appears to works pretty well and could eliminate much of the conventional labor of air drying all of the adobes and mortaring them into place. It is basically a method that combines formed bricks with hand-piled adobe (or pise) for a system that is quite maleable in wall shape and appearance. Describing how to do this is half of the book; the other half is an exhortation to think out of the box, have fun, and be creative. Michael shows many examples of his own projects and those of others that do just that. It is a fun read that will make you want to get out in the dirt and play!

Earth Construction Handbook: The Building Material Earth in Modern Architecture by Gernot Minke, 2000. Which building material 1 - Absorbs and desorbs humidity faster, and to a higher extent, than any other? 2 - Produces hardly any environmental pollution and can be recycled any number of times? 3 - Balances indoor climate and moisture thus creating an extremely healthy environment in which to live? The answer is EARTH. In nearly all hot-dry and moderate climates of the world earth has been the predominant building material. Earth construction techniques have been known for more than nine thousand years and, even today, one-third of mankind lives in earth houses. The Earth Construction Handbook provides a survey of applications and construction techniques, including physical data, and explains the materials specific qualities together with the possibilities of optimising these. The information given can be practically applied by engineers, architects, builders, planners, craftsmen and laymen who wish to construct cost-effective buildings which provide a healthy, balanced indoor climate.

Simone Swan: Adobe Building by Dennis Dollens, 2006. Like an organism sitting and breathing on its site in the Chihuahuan desert, the Swan House is a building of organic beauty and hybrid cultural intelligence. Simone Swan has created an architectural and environmental project that re-examines and promotes traditional adobe building while introducing compatible forms, such as the Nubian vault and dome. Swan studied with the great Egyptian architect Hassan Fathy in his Cairo studio and after his death in 1989 adopted his mission of helping house the world's poor. Simone Swan: Adobe Building is the first book to discuss and illustrate Swan's architecture while also chronicling one of her annual workshops in Dollens' first-hand account. Dollens suggests that by biologically analyzing historic adobe we may be able to hybridize its constituents as replacements for current toxic materials, creating new biomimetic, adobe-related building materials suitable for green architecture.

Ceramic Houses and Earth Architecture: How to Build Your Own by Nader Khalili, 1996. This book shows how to build vaults, domes and arches with adobe blocks. It then goes on to suggest how to actually fire the structure like pottery, with a glaze. It is a fiscinating concept that has seen little use, partly because the firing process can be rather polluting. This book has been updated to discuss the SuperAdobe building method of building with earthbags.. I recommend this book to everyone who is interested in alternative building methods.

PLANS

Santa Fe I
Sven Alstrom , Designer

This one story Santa Fe Style ranch home has an attached two car garage and is based upon 24 inch wide straw bale (or adobe) construction on a concrete block foundation & concrete spread footings with crawl spaces and a partial basement. Though not designed as a passive solar house, it is designed for primarily hot weather climates. Natural interior plaster and natural exterior stucco are recommended. The interior square footage of the house portion is 2,336 square feet, measured on the inside of walls. In addition, the garage has 20 x 22 ft. clear inside dimensions. This home was originally designed for the main entrance to face east so that the kitchen is southeast for ‘ayurvedic' benefits – the plan also works well with the garage on the north side or by ‘flipping' the plan with the bedrooms on the south.

For more information about this plan, and many others, visit our sister site www.dreamgreenhomes.com, where you will find a wide range of plans for sustainable homes, greenhouses, small buildings, garages, and food storage space for sale. Dream Green Homes is a consortium of outstanding architects and designers, who have pooled their talent and expertise for your benefit.
