Sylvia Cook, Principal

Sylvia is a former high school physics teacher with a passion for sustainability and a desire to create beautiful, natural homes. In 2009, that passion led Sylvia to create Aerecura Rammed Earth Builders, the first rammed earth building company in Ontario. 

A decade later, Sylvia has helped bring rammed earth to the forefront of sustainable building in Ontario. She has appeared on on CBC's Disrupting Design and had her rammed earth home featured in The Globe and Mail. Sylvia welcomes the opportunity to share her knowledge on sustainable buildings in class and conference settings, and is available upon request.
