Rachel Ross lives in a round eco-home on 1 ½ acres near an artsy town in B.C., the “little Berkeley of Canada.” She and her husband, Lars, own a green prefab homebuilding company, Mandala Homes. They design, build and ship round energy efficient homes to out-of-the-box-thinking clients all over the world. Together with their teenager, Poppy, they built the first ENERGY STAR qualified house in BC. It’s one of series of round buildings on their demonstration project of sustainable, artistic and natural building techniques and materials. Their home is their design innovation playground! Rachel is a writer (check out her blog), a Permaculture designer and serial entrepreneur.
