Stephen Kieran's work is the result of a thorough examination of the craft of architecture at all scales.

From early adoption of building information modeling and environmental analysis tools, to close collaboration with fabricators and engagement with materials scientists, Steve shifts expectations of the role of architect. Examples include Loblolly House, an off-site fabricated home in the Chesapeake Bay; SmartWrap™, a mass-customizable building envelope exhibited at the Cooper-Hewitt, National Design Museum; Cellophane House™, a fully recyclable, energy-gathering dwelling exhibited at The Museum of Modern Art in New York; and the Embassy of the United States in London, which employs strategies to significantly reduce energy consumption and sets an agenda to achieve carbon neutrality. 
More recent projects include a renovation and addition to arts and music facilities at Wellesley College, House Renewal projects at Harvard University, a new School of Engineering at Brown University, and three new student life buildings on the University of Washington's North Campus. 
Under his guidance, the firm has received over 260 design citations, including the AIA Firm Award in 2008 and the Cooper-Hewitt National Design Award in 2010. Steve and Partner James Timberlake were the inaugural recipients of the Benjamin Latrobe Fellowship for architectural design research from the AIA College of Fellows in 2001. Since 2002, they have co-authored seven books on architecture, including the influential book refabricating Architecture and their newest monograph, KieranTimberlake: Fullness
Steve lectures internationally to academic and industry audiences and to the broader public, with talks in London, Montreal, Puerto Rico, Rome, and Tel Aviv. He has served on several award juries, including the AIA College of Fellows Latrobe Prize Jury. 
In addition to his architectural practice, Steve has held visiting professorships at the University of Pennsylvania School of Design, the University of Washington, Yale University, and the University of Michigan, and a full-time professorship at Princeton University.
