Howard Switzer is a practicing architect with more than 30 years experience designing passive solar homes and working with owner builders on many alternative building techniques and materials. With his wife, Katey Culver, a permaculture designer, they formed ecoville architechs and have been helping owner builders and other groups build healthy passive solar buildings using plastered straw bale construction and other uncommon building techniques. They present workshops at the Ecovillage Training Center and around the region annually as a vehicle to educate folks on what truly constitutes a sustainable building and how to build one. Their presentations are designed to instill people with confidence in natural building materials showing them how earth and straw can be used to create a viable future. Their work has been featured in Mother Earth News. They live off grid, high on the banks of the Buffalo River in Perry County.
