We are a non-profit organization whose members are designers,contractors, owner builders, and people interested in straw and natural building. We serve as a clearing house for information and as a network of resources. Our mission statement is:

 "to further the practice of straw building by exchanging current information & practical experience, promoting and conducting research & testing, and making that body of knowledge available to working professionals and the public at large.” 

Our goal is to have a very real impact on how people build.

Since 1996, our members have worked to develop testing and to improve techniques and standards for building with straw, in order to gain its acceptance by municipalities, officials, lenders, and insurance companies throughout California, and beyond. There are now many fine examples of permitted straw bale homes throughout the state, as well as a number of commercial buildings, which stand as a testament to this pioneering work. Please see our history, code update, and testing pages for more information.

CASBA members have not only broken new ground at home. Individually, through affiliations, some have been instrumental in bringing straw bale building to far-flung places around the globe: consulting, teaching, building, and collaborating – on projects to combat pollution, conserve resources, rebuild after natural disasters, and improve community services and housing in impoverished areas.

Although we are a very diverse group, we share similar hopes, dreams, and beliefs for building a better world through the wise use of natural materials, intelligent design, and stewardship of our resources. This is what binds us together and gives us a common language and spirit.

At our annual West Coast Natural Building Conference, we learn from speakers and forums, and also from each other…sharing our experiences and the lessons learned. Members flock to this event from up & down California, as well as visitors from other states and countries. Plenty of time for socializing lends a festive air of “family reunion” to the event. We welcome anyone who shares our passion.

CASBA is fiscally sponsored by the Tides Center, a 501(c) (3) non-profit organization.
