WRNS Studio

WRNS Studio is a San Francisco architecture firm known for climate-minded design and big technology campuses. Founded in 2005, the practice handles architecture, interiors, and planning, and Fast Company named it one of the world’s most innovative companies in 2024. WRNS designed Microsoft’s Silicon Valley Campus and has built a reputation for low-carbon, daylight-driven buildings. On The Kelsey Civic Center in San Francisco, WRNS co-designed a disability-forward affordable housing project that treats accessibility as the starting point rather than a retrofit. With a few hundred staff across U.S. offices, the firm works in housing, education, workplace, and civic projects where sustainability targets shape the design from day one.

WRNS Studio is an architecture, interiors and planning firm founded in San Francisco in 2005. It has grown into an office of roughly 145 people with additional studios in Honolulu, New York and Seattle, and it built its reputation on sustainable design applied across a wide range of building types.

The portfolio splits between private and public work in a way that sets the firm apart. On the corporate side, WRNS has designed workplaces for technology companies including Microsoft, Google, Meta, Adobe, Amazon and Airbnb. On the civic side, it takes on education campuses, transportation and urban mixed-use projects, and has partnered with the University of California, the Trust for Public Land and San Francisco’s Chinatown Community Development Corporation.

Sustainability is stated as a founding value rather than an add-on, and the firm frames its designs around environmental performance and contribution to the public realm. That posture has earned recognition including a spot on Fast Company’s list of most innovative architecture offices and a Best of Practice award from The Architect’s Newspaper.

For clients browsing this directory, WRNS is a mid-to-large design practice equipped for complex institutional and workplace projects, with West Coast roots in San Francisco and Honolulu and a coast-to-coast reach through its New York and Seattle studios.
