VIVAMARÉE ZÖE HANSEN (Viva)
Viva (mudbloodbuilds.com) is a longtime builder. He was introduced to cob through his mother Claudine Desirée of Cruzin’ Cob Global who studied with Michael G. Smith in 2001. Viva spent countless afternoons in his backyard mixing mud with his mom to help build the first legalized cob structure in Santa Cruz, CA.
It wasn’t long before Viva started experimenting with pizza ovens, garden walls, and eventually whole buildings on his own. His love for earthwork took him across the world from West Africa and South America to Mexico and Europe. He’s built numerous structures and taught in many workshops. He currently resides in Colorado, specializing in low-tech, high-efficiency, wood-fired appliances.
In 2022 Viva launched Mudblood Builds as a way to collect and focus his work in a more distinct direction. He chose the name Mudblood as a reminder of the simultaneous power and danger of racial and genetic politics which shape our relationship to land, our right to life, and our access to the critical resources of the earth. Human health and the health of the earth are inextricable. Mud is in our blood, and the flesh and blood of the Earth is mud...
Mudblood serves to preserve this symbiosis.
Sasha Rabin
Sasha Rabin fell in love with natural building in 2002, when she began her building career with an apprenticeship at the Cob Cottage Company. Since then she has taught extensively through organizations that she co-founded, Seven Generations Natural Builders and Vertical Clay, and through collaborations with The Yestermorrow Design Build School, The Canelo Project, Cal-Earth, The Solar Living Institute, and Quail Springs Permaculture. Teaching natural building has brought her as far as the Permaculture Research Institute (PRI) Jordan and PRI Kenya and runs her own natural building organization, Earthen Shelter. She also directs the Natural Building Advocacy program at Quail Springs. She recently relocated to Northern CA where she was born and raised and is excited to be teaching up here once again!
Athena Steen
Athena Steen was one of the pioneers of the straw bale revival, building her first straw bale home at the age of 19. In 1989, with her husband Bill, she founded The Canelo Project, a center for natural building and cultural revival in southern Arizona. Together they have developed many innovations in straw and clay construction, ranging from simple straw bale pinning techniques to high-fiber “light adobes” to a revival of poured adobe floors. They emphasize everyone’s capacity to house themselves beautifully and inexpensively, using local natural materials and innate wisdom. They have worked extensively on low-income housing projects in Mexico and traveled and taught all over the world. Athena and Bill have also written half a dozen books, including “The Straw Bale House” (Chelsea Green, 1994).

Blair is a certified permaculture designer and teacher who has studied with the best(2007). Teachers like Dr. Elaine Ingham, Geoff Lawton, Darren Doherty, Penny Livingston, Broc Dolmon, Ian Davidson, Steve Gliesman, and Michael Flynn. (2004-to 2016). Since Blair's teenage years, he has been exploring practices to awaken the inner self and align with the world outside. This inquisition has led him to explore meditation, yoga, plant medicine, traditional west African drumming, and other healing arts. The fusion of internal work with the external has led Blair on a journey to make his work into visible prayers. listen to an interview.
Blair was also the original founder of Common Vision (1999), (www.commonvision.org) a nonprofit organization responsible for planting thousands of fruit trees in California, most of which were planted on California’s school campuses by a caravan of earth educators running on waste vegetable oil. In the first ten years, Common Vision used traditional and circus arts performances to inspire children toward a healthy, hands-on relationship with the earth. Blair has worked internationally to propagate an additional 7000 trees in Guinea, West Africa. (2008) He has also studied at Cal-Earth (2010) and helped build a super adobe dome structure for a school in Dogon country, Mali, West Africa (2010). He has participated in other natural building workshops covering straw bale, plastering, light straw clay, wattle, and daub as well as catenary vaults. (2008-2016). In early 2012 Blair spent time working with the Huichol Community Center to develop a 4-year strategy to develop water and make certain changes to enhance the productivity of their traditional farming practices. 2014-2015 Blair traveled to Peru to explore his fascination with plant medicines and indigenous culture.
Settling into the hills of Willits (2012) inspired Blair to have an intimate relationship with the watershed, designing Wanosh Forest Gardens and Healing Grounds based on a regenerative relationship with the surrounding environment in a multifaceted approach. By keeping water at the core, agroecological development, forest regeneration, animal rotation, aquifer recharge points, natural building projects, and nursery work are placed providing a developing model of design for local neighbors and beyond.
In the winter of 2017-2018, Blair went to Rishikesh, India to study with masters of lineage to become a Certified Yoga Teacher. This journey was the transition and initiation to helping others fine-tune their own internal practices and integrate them through the recalibration of the Heart, Health, and Hands.
Since 2019, Blair has been working with the Forest Reciprocity Group (FRoG) to develop strategy and educational programming to help people who live in fire-prone forested areas understand our relationship with the forest, and health fire while making use of small diameter poles thinned in fire prevention work. https://forestreciprocity.org
Additionally, Blair has been working professionally design in the private sector.
Continuing on the path of service Blair created Wanosh Forest Gardens to be a campus for those who engage with themselves and the land. He is inspired to help people focus their self-practice towards a regenerative lifestyle internally and externally. He is excited to continue helping people outside of the gardens with broad acreage land and water regeneration.
