2013 Complete Cob Natural Building Retreat
This one day to three week long sacred space class will invigorate the soul and body, for each day will start with yoga and organic fresh food, a community of like minded students who will be along for this journey in the woods of the Yuba watershed. Rob Pollacek of California Cob teaches clearly all aspects of a naturally built building, from the foundation, raising the walls of cob, setting the framing for the roof, and correct construction of an earthen roof. Lessons in sustainability, natural living, community, and personal growth are all a part of this retreat. You will leave this retreat fully confident in building a cob building from scratch from your local materials. Each day can be taken as an individual class; see syllabus section below.
One week option now available! For a Cob Intensive, join us from September 10-17th. If you are interested in foundation or earthen roof more, please contact Samantha or Rob directly at (530) 362-8082.
This retreat will be beautiful, sited on a rolling slope under oak trees on the edge of the Yuba River. Our food will be prepared with love and joy by an experienced chef, using organic food and some wildcrafted plants. The San Juan Ridge is a warm, welcoming place chock full of inspiring natural buildings which we will tour, and the weather in September is exceptional. The Ridge, as it is known, has a yoga studio, a cultural center, a natural food store and an cafe within 10 minutes of the site, even though it is very rural. Additionally, this workshop will be filmed to create two short films about cob building. To talk to Samantha or Rob about the class, you can call Samantha at (530) 362-8082 or Rob at (530) 913-0846.

About the Food:
We love good food, and we will be eating well! Mikhel Neshat, who cooked for our last California Cob/Mud and Pearls collaboration will be creating healthy, fresh food to nourish and sustain us. Please let us know your food allergies. We will be eating some locally sourced, wildcrafted food. Samantha was inspired by her experience at Eselen and we’ll be eating food that is grown by local farms and families. Locals: we strongly encourage you to eat with us. It will be harder for you to make sure that you eat well since the days will be intensive. Call Samantha if you are a local and want to bring your own food, or eat less meals than scheduled.

About the Natural Building Tour:
Visit the largest rammed earth in the Western United States, the largest cob home in California, and a multitude of other natural homes outside of Nevada City.
During this day-long natural building tour we will be traveling the Yuba River area, touring a variety of different properties featuring natural building techniques. Our tour focuses on cob houses and structures, straw bale construction, rammed earth, earthen floor and plaster, super adobe, repurposed wood and much more. The tour will begin at 9 am and locally sourced lunch will be provided. Three vans staffed with knowledgeable builders will guide you to each site; providing opportunity to ask questions. Each site will have the builder there so that technical, aethestic and building details can be answered.
Tour attendees will meet at the juncture of Tyler Foote Road and Highway 49 to hop into vans that will take them to each site. Please bring your own water bottle, snacks, and note pad. Your ticket helps to support the educational outreach of Mud and Pearls and Synergia Learning Ventures.
Topics addressed will be permitting and building codes, benefits of each type of structure, combining elements for creating the “perfect” home, and ease and struggles. Experience the health and beauty of these natural homes during this well staffed tour. Tour admission is included in class cost, if you are wanting just the tour it will be $95. Register for Natural Building Tour
Camping will be on the building site, on a 1700 acre nature reserve. Hot outdoor showers and composting toilets will be provided, hiking trails and access to the Yuba River for swimming are all on site. Hot cooked gourmet meals will be prepared and served in our area. Local natural food store Mother Truckers is only 2 miles away. Students will need to bring their own camping gear (tent, bedding, clothes, flashlights, etc) but will not need to bring food preparation materials. Materials for the class will also be required.
About the Yoga:
Nevada County has a great wealth of yoga teachers, who have studied from Acro Yoga to Ashtanga. We will be joined by these teachers to start our day limber and centered. We feel that starting each day with a healing, fun and healthy practice will make our time even better.
About Rob Pollacek of California Cob:
Rob Pollacek has been building and teaching with cob and other natural materials for the last 14 years. He has built cob and strawbale homes, including the 3000 square foot cob home he built for his family. He also specializes in cob garden walls, cob saunas, living roofs, earthen plasters, earth floors and cob benches, of which he has built more than 25. He has been in the forefront of the tractor cob movement for the last decade, refining a system of tractor cob that produces 5 cubic yards of high quality cob an hour, and a moveable cob form system, which allows for quick cob wall building. He was trained by The Cob Cottage Co., and graduated from their first apprenticeship program in Coquille, Oregon, in 2001. He brings with him a thorough understanding of cob construction, as well as a deep love for this ancient building technique. He is an excellent and approachable teacher, as well as a father of two girls and avid outdoorsman. (530) 913-0846
