Margaret Castillo joined Helpern Architects in 1996 and was named a Design Principal in 2000.
She has worked on the Nave of Sterling Memorial Library at Yale University; the exotic 1887 Lockwood DeForrest house on East 10th Street in New York City that New York University converted into the Edgar M. Bronfman Center for Jewish Life; and several of New York City’s great “Carnegie Libraries.”
She has also restored five historic homes owned by Yale, notably the fine Skinner-Trowbridge House on Hillhouse Avenue that became the International Center for Finance of the School of Management. Margaret “rescued” the fragile Davies Mansion to create Yale’s Center for Global Studies – a building that is a dead ringer for the Addams Family’s home. Add to this litany the restoration of the great dome of Low Memorial Library at Columbia University.
The firm’s sustainability leader, Margaret dedicated her year as the 2011 president of the New York Chapter of the American Institute of Architects to sustainability and continues that advocacy as part of the AIA’s regional resilience program outreach. She was the Chapter’s interface with the Mayor’s Office of Long-Term Planning & Sustainability and the NYC Department of Buildings as Mayor Bloomberg advanced his PlaNYC “greater, greener” goals. She has also spoken on behalf of AIA at sustainability conferences at the United Nations, Rio de Janeiro, Tokyo, and Amsterdam.
Interviewed regularly by the New York Times, Crain’s New York Business, The Real Deal, and the New York Observer, Margaret is a member of the New York Building Congress and currently serves on the board of the New York Fine Arts Federation.
Margaret received her Bachelor of Arts degree from Boston College and a Master of Architecture degree from the Harvard University Graduate School of Design.
