October 11-17

Batch Rocket Thermal Mass Heaters

Instructor Kirk Mobert

Each workshop is organized into two parts, the weekend Intensive (Friday through Sunday) will include the bulk of theoretical and practical training, followed by a 4-day Practicum (Monday through Thursday) focused on hands-on building experience. Participants are encouraged to attend both the workshop and practicum for the full experience which is incentivized by a reduced workshop tuition.

Workshops fees include an all organic, local as possible lunch and dinner as well as camping/housing options. As harvest time progresses we'll be eating more & more from the garden on site.  Fee also includes optional guided early morning yoga class.


For friends interested in going deep we are inviting 6 people to do an immersion through the Natural building series. This immersion allows participants to attend workshops for free and have all meals provided in exchange for weekly work hours, primarily toward building, but also other supportive tasks for workshop prep and facility maintenance. ​
