Our courses offer comprehensive lectures and hands-on demonstrations in the classroom that students put into practice during the building project completed during the course. We teach students how to envision and create beautiful spaces with the amazing abundance mother nature provides. Stay tuned for upcoming courses, tips, and resources on natural building methods as well as Permaculture design here in beautiful Costa Rica.

Pura Vida

Rodolpho Saenz

Rodolfo Saenz began his career as a craftsman, furniture maker, and builder over 30 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. Learn more at

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, he 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. 

Soon thereafter he joined the build 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 Envision festival each year.

In 2015, he attended a 2-week earthen building course at Rancho Mastatal, focusing on cob, clay and lime plasters, natural pigments and paints, and tadelakt, an amazing waterproof limestone plaster technique from Morocco.

After participating in and leading many natural building projects in Costa Rica, Trey is confident in his skill sets for teaching and empowering others to build with local and sustainable materials, in harmony with nature.

Motivated by sustainable building practices, he aspires to evolve current paradigms to lessen the environmental toll by technique & practice. Keeping integrity with the core tenements of his business philosophy: pursuing passion projects, and cultivating friendly relationships with clients and colleagues; are paramount, and involving the clients and communities in the building process where possible. His style is one of deep planning, skewer modeling, conventional rigging, and orchestrating the crew into a multitenticulated installation creature brimming with passion and morale. He is conscious of the energy that spaces generate as it moves attention and awareness. He is moved by the process of creation of these spaces and the level of intimacy between those who collaborate in its creation and enjoyment. Joshua is excited to share his knowledge and level of expertise with apprentices in various places on their journey building bamboo structures. He is also motivated to refine his craft with continued learning from his colleagues, crew, co-creators and environments.
