Learn state-of-the art skills in sustainable construction that you can apply to your home building projects using trimmings from your backyard trees. Participants will receive expert instruction in whole tree design, framing, and finishing. Architect Roald Gundersen, who specializes in solar, straw bale and whole tree buildings, will show us how to build using un-milled trees harvested from forest thinning for columns and beams (for more on Roald's work, go to www.roaldgundersen.com). As with unprocessed food that retains more health value, wood used in its natural state retains 50% more of its strength than milled lumber. In this three day learning-by-doing workshop, you will help construct a 16 foot round wood shelter that will cover our new cob oven. You will learn about preparing round wood on Friday (including forestry, tree selection and peeling bark), assembling the structure on Saturday, and completing the roof on Sunday. Participants also will observe previously constructed round wood and strawbale structures on the farm and see how well they are holding up after several winters. The finished product in functional, beautiful, and inspiring! Class takes place from 8:30am to 5pm daily. Discount available as part of Sustainable Building series.  Inquire about enrolling for individual days at $90/day.
