NADAAA is an architecture and urban design firm led by principal designer Nader Tehrani, winner of the American Academy of Arts and Letter's 2020 Arnold B. Brunner Prize, member of the Cooper Hewitt, and newly elected member of the American Academy of Arts and Sciences. Tehrani is also professor and former Dean of the Cooper Union's Irwin S. Chanin School of Architecture.

NADAAA has evolved over three decades with a focus on the transformation of the building industry, innovative material applications, and the development of new means and methods of construction, especially through digital fabrication. Rather than focus on typology, NADAAA's portfolio is built on process, with examples of institutional, academic, housing, commercial, and civic projects.

NADAAA boasts an unpresented nineteen Progressive Architecture Awards, numerous national and international awards, and consistently places among the top design firms in Architect's annual ranking, where it has been selected as the top national firm three years in a row.
