Which firm designed Levi's Stadium?

Architectural firm HNTB designed Levi's Stadium.

HNTB served as the stadium's architect, shaping an open-air venue intended to support football, concerts, major events, and an improved fan experience. The design brief also emphasized environmental performance, helping make sustainability a visible part of the building rather than an afterthought.

The stadium was developed for the San Francisco 49ers after plans for a new venue in San Francisco stalled. Construction began in 2012 in Santa Clara, and the completed stadium opened in 2014. HNTB's work included the overall architectural design; other specialist firms handled structural, civil, mechanical, electrical, and construction roles.

That distinction explains why answers such as AECOM, Populous, or Gensler can seem plausible: large stadium projects commonly involve many engineering and consulting companies. They were not the firm identified as Levi's Stadium's architect. HNTB is also known for transportation and civic infrastructure work, making the stadium part of a much broader architectural portfolio.
