Stephanie Kingsnorth


Principal | Executive Director

“We urgently need to act to safeguard our environment, so it’s all the more important to look at how we can reuse existing buildings. Adapting them to contemporary needs is a great way for designers to help manage finite material and carbon resources. And the programmatic and technical challenges involved with updating existing buildings provides exciting opportunities for creative design thinking to provide spaces that are more sustainable, more accessible, and more inclusive of diversity.”

Stephanie’s passion for existing and historic buildings stems from a childhood immersed in England’s historical architecture and later exposure to a diversity of architectural styles when she moved around the United States.  Throughout twenty-five-plus years of creative and technical practice working with historic, midcentury, and recent-past buildings for cultural icons, civic landmarks, and academic campuses, she has steadfastly advocated for the essential value of renovation and adaptive re-use—not simply to preserve architectural heritage, but to provide current and future generations with meaningful spaces of renewed and sustainable relevance. In the academic realm, she strives to support the educational mission by designing rich, multi-faceted student experiences in existing buildings, inclusive of libraries, student unions, and student residences.
