This innovative course in the rainforest of Costa Rica provides students with a unique opportunity to explore the design/build process using earth, straw, cob, stone, site-milled wood, bamboo, and recycled/reused materials. The class will work on a group project at the Rancho Mastatal environmental learning center or a small community project in the village of Mastatal. Students will have the chance to collaborate on a variety of design assignments. The class will survey and discuss different building techniques and work hands-on and in-depth with a featured number of them. A field trip to investigate local vernacular architecture is one highlight of the course. The class is ideal for architecture, environmental studies, and building technology students and professionals as well as those interested in incorporating natural building techniques into their own projects.
