Natural Building Internship
March 27 - May 12
Quail Springs, California

This 7-week program is a chance for up to 6 people to gain more in-depth experience with a variety of natural building techniques.  It is designed for people with some natural building experience who want to deepen their skills in a mentored environment.  We will be working on a variety of projects using different building styles and techniques, with the focus being a small cob structure. You will get to assist and partake in the one week natural building workshop. 
Focus of Internship: During these 7 weeks, the interns will be working with Sasha Rabin and John Orcutt on an almost start to finish project.  Interns will begin the program prepping the site for this build before the natural building workshop begins.  This will include design discussions, earthworks, drainage, building an earthbag foundation, making adobe blocks,  and some woodwork, etc. Following the workshop the interns will continue progress on this building and explore other projects and techniques the group is interested in learning.

Introduction to Cob and Natural Building
April 10 - 15, 2017
Maricopa, California

Cob building combines clay sediment, sand, fiber, and water, and is hand sculpted to form walls, benches, ovens, and fireplaces. Cob building makes use of readily available, affordable, non-toxic materials to build beautiful, organic structures. 

The course is appropriate for both first-time builders and for professionals in the building trade who are interested in natural materials. In this cob workshop, we focus on the characteristics of the natural materials most commonly used in construction: clay soil, sand, and fibers. Our main focus will be cob, though we will touch on various other building techniques that utilize the same materials, including adobe block, light straw-clay, wattle and daub, and plasters. We will discuss how to find and choose appropriate soil for construction, how to create various mixes, how to attach wood to earthen walls, and how to use earthen materials to build walls, sculpt niches, shelves, and furniture.

See www.quailsprings.org for more information.
