Written along with Chris Magwood, the authors show how buildings are culprits but stand poised to act as climate healers. They offer an exciting vision of climate-friendly architecture, along with practical advice for professionals working to address the carbon footprint of our built environment.

    CASBA director Massey Burke and member Bruce King both appear in a video devoted to building with straw, recently released by Patagonia. The credits also thank CASBA and members David Arkin, Jim Reiland, and Anthony Dente. Participating in the making of the video was an unexpected honor, and a delight. Thank you to Yvon Chouinard & architect Dylan Johnson for championing straw building, and giving us the opportunity to help!

    Weather-Resistant Exterior Plasters with Clay and Lime workshop in Phoenix, AZ

    This 3-day course replaces a previously arranged straw bale building workshop scheduled for this same time that has been moved to a future date in November. 

    Taught by Athena and Bill Steen, this workshop will focus on stabilizing clay plasters for use as an exterior finish. We will explore a variety of ingredients that can be added or applied to help clay resist water. Lime plaster will also be covered to a lesser extent. The course will cover theory and mixes with plenty of hands-on opportunities for all participants. 

    Existing exterior strawbale walls plastered with a clay base-coat will be finish plastered during the course. Different methods and techniques will be used on various walls around the two existing buildings.

    This workshop will be held Friday March 4- Sunday, March 6, 2022. The cost for the plaster workshop is $375 which includes meals, materials, and instruction by the amazing Steens.

    To register, contact Susan Ontiveros at 602 561-9621 or email her:
