This course will take place from July 23rd - July 29th, 2021 at EcoMaste in Diamante Valley, Costa Rica. EcoMaste is an eco-lodge and holistic learning center focused on designing a pathway to regenerate the earth, aiming to exemplify the virtues of integrity, sustainability, and love.

Come to EcoMaste and experience the abundance of life in the jungle. Here you will have an opportunity to commune with nature, ground yourself, enjoy our nature trails, cascading river, harvest fresh foods from the property, vibrant delicious organic plant-based meals, and learn the skills you need to build with bamboo as well as other natural materials.

Our goal is to give students a transformational and regenerative education so that they can be empowered to create a lifestyle rooted in sustainability and collaboration with nature. 

Learn from world-renown Bamboo Master, artisan, and craftsman, with over 35 years of experience, and founder of Bamboo School CR, Rodolfo Saenz and founder of Natural Building Costa Rica and Bambu Mundo Trey Abernethy. 

This course is designed for those who would like practical natural building skills and hands-on experience working with bamboo. It would suit owner-developers, professional contractors, permaculturists, or anyone looking to build with regenerative and sustainable materials and methodologies. No prior experience or special skills are necessary. Just a reasonable level of physical fitness and willingness to learn.

The course starts at 9 a.m. Friday, March 26th. We advise everyone to arrive by 4 p.m. on Thursday, March 25th. Dinner and selected accommodations for the night of the 25th are included. The last day is Thursday, April 1. Breakfast is provided on the morning of April 2nd and check out is by 10 a.m.

Rodolfo Saenz

Rodolfo Saenz began his career as a craftsman, furniture maker, and builder over 35 years ago. He first learned to work with wood and later received training in a variety of techniques with bamboo from a Taiwanese Master, which led him into bamboo furniture design combined with hardwoods and various other materials.

Originally trained in conventional construction, he switched gears to natural building methods and design with a concentration on bamboo, cob, and earthen plasters. Rodolfo is passionate about sharing his skills and knowledge by teaching sustainable building and design and has over a dozen years of experience teaching courses.

Trey Abernethy

After 12 years of conventional construction in the US witnessing wasteful, toxic, and unsustainable methods, he knew there was a better way to build. While living in Florida, Trey began taking courses and workshops on cob, adobe, and earthen plasters. In 2013, he moved to Costa Rica and continued learning about natural building, permaculture, community, and holistic living.

After completing his Permaculture Design Course shortly after arriving in Costa Rica he attended a week-long course on building with bamboo, cob, adobe, and plasters with Rodolfo Saenz. This course inspired and encouraged him to work with bamboo and soon thereafter he joined the building crew for the Envision festival, learning from a range of experts on bamboo design and building. Trey continues to work on large-scale bamboo design and builds at the Envision festival each year. 

After participating in and leading many natural building projects in Costa Rica, Trey formed Natural Building Costa Rica in 2016 and began organizing and teaching courses with Rodolfo Saenz.
