Clay Oven building workshop

Presenting our first collaboration with Ayal Bryant, renouned earth builder and plasterer, based in CR with BarroVico. Ayal Bryant has over ten years experience in natural building and during the past 5 years has specialized in building cob ovens for restaurants and homes all over Costa Rica. His passion for natural building comes from his family who have worked on restoring and rebuilding typical Costa Rican adobe homes which meant he spent most of his summers in mud holes helping prepare adobe mix. Once graduated as a product design engineer he pursued a MSc in sustainable building in the UK and returned to Costa Rica to build the largest super adobe house in Central America. During this time he also started to build cob ovens, his first one was in his mother's yard but as people began to see how it was built and the end result orders started to come in for customs ovens to be built all over the country. This allowed Ayal to dedicate the past 5 years to build over 25 ovens and has become the only profesional cob oven builder in Costa Rica.
