2012 International Straw Bale Conference - Estes Park, CO

From Colorado Straw Bale Association to Natural Building Alliance

Colorado Straw Bale Association (COSBA) began in 2000 to address the growing need for public understanding of straw-bale construction in Colorado and the surrounding region.  We have held education workshops and annual conferences throughout the state that include keynote speakers, panel discussions, and local straw-built home tours.  In 2012, COSBA hosted the extremely successful International Straw Building Conference in Estes Park, CO. 

With the continuing growth of natural building, COSBA decided that 2019 was the year to grow as well.  In an effort to include all natural building techniques and to encompass a larger geographical range, we decided to rename our organization to the Natural Building Alliance (NBA).  With our expansion, we will continue to advocate for the benefits of straw bale construction.  Additionally, we will also be advocating for all natural building techniques.  Whether, compressed earth block, hempcrete, light straw clay, cob, or any other natural materials-based construction technique, NBA will be at the center of providing education and hands-on experience to the public.  Although Colorado has been our region of focus until this year, NBA will be a voice for not only Colorado but for all of the inter-mountain states and beyond.
