NBBJ has been recognized as a TIME 100 Most Influential Companies (2025), and a six-time recipient of the Fast Company Most Innovative Architecture Firm award. NBBJ was also recognized as "Best in Business" by Modern Healthcare, named the fastest-growing architecture firm by Architectural Record, and designated by Wired as the "architecture firm of choice for tech companies."
History NBBJ was founded in 1943 by Seattle architects Floyd Naramore, William J. Bain, Clifton Brady, and Perry Johanson, originally under the name Naramore, Bain, Brady & Johanson. Formed during World War II to undertake large-scale federal projects such as the Bremerton Naval Shipyard expansion, the partnership remained intact after the war and evolved into one of the Pacific Northwest’s largest architecture firms.
In 1976, the firm merged with Columbus, Ohio-based Nitschke–Godwin–Bohm, formally becoming NBBJ and expanding its national reach.
In 2010, NBBJ merged with Cambridge-based urban design firm Chan Krieger Sieniewicz (CKS), enhancing its presence in the Northeast and adding to its urban design capabilities.
In 2020, NBBJ expanded its expertise in immersive and experiential design through its acquisition of ESI Design, a New York-based studio known for integrating interactive media and technology into the built environment.
Sustainability and Climate Initiatives The firm was an early signatory of the Architecture challenge, a global initiative to reduce fossil-fuel greenhouse gas emissions in the built environment. In 2025, NBBJ was ranked #1 among leading US architecture firms in Energy Use Intensity (EUI) reduction as part of the AIA 2030 °Challenge, reporting a portfolio-wide reduction of approximately 75%. The firm also ranked among the top two firms by gross square footage of projects meeting EUI targets.
NBBJ is also CarbonNeutral® certified by Natural Capital Partners and a signatory of the Amazon Climate Pledge. Research and Innovation NBBJ has developed research initiatives focused on the relationship between the built environment and human performance, including studies on climate, temperature, and cognitive function in partnership with neuroscientist Dr. John Medina. In addition, the firm has developed partnerships with The New York Academy of Sciences to study what scientists want in their lab buildings, Professor Dr. Raj Choudhury of the London School of Economics (previously with the Harvard Business School) to design workplaces in an era of disruption and Professor Dr. Kevin Schulman of the Stanford’s Graduate School of Business to inform future hospital design in the age of artificial intelligence (AI).
