Stephen Kredell AIA, LEED AP Architect

Stephen Kredell was one of the founding partners of McLeod Kredell Architects prior to joining gbA. He believes that architecture grows out of its particular place and time, and that it has the potential to inspire. He believes that community engagement is of paramount importance and that we all can contribute in a thoughtful way to our built environment. He recently led a group of 13 year olds in building a shed for a Habitat for Humanity house.

Before moving to Vermont, Stephen practiced in New York City and Pittsburgh. Stephen’s projects range from university buildings to single family homes. The work has received numerous awards both locally and regionally, and has been widely published in magazines, journals, and books.

As part of his community engagement focus, Stephen co-created a pro-bono design build organization that combines the efforts of students and professionals to bring good design to select small community projects. These projects and the organization itself have been widely recognized for their successful results.

Stephen teaches at Norwich University and Middlebury College. He also has taught at Community College of Vermont and the New Jersey Institute of Technology. He has served on juries and as a critic at schools throughout the US and beyond.

As part of the professional community, Stephen has served nationally as the American Institute of Architects’ (AIA) New England Small Firm representative.
