Overview
A carbon-zero energy workplace in the historic Mills Building models new ways of working while reaffirming Gensler’s commitment to downtown San Francisco.
Opportunity
With 60-year roots in San Francisco, Gensler’s new home needed to reenergize the city while introduce a sustainable, experimental vision of the future workplace.
As cities like San Francisco grappled with an uncertain work landscape post-pandemic, the role of the workplace was fundamentally changed. For companies that opt to maintain a physical presence in the world of hybrid and remote work, one-size-fits-all workplaces are no longer viable as employees seek out multi-layered experiences worthy of their commute. Seizing these challenges as opportunities, Gensler recommitted to its founding city with a 12-year lease in the historic Mills Building, aiming to support San Francisco’s ongoing recovery and redefine the office in a new era of work.

Why This Matters
01
Workplace as Destination
The project asked how design could make coming to work purposeful again, supporting focus, collaboration, hospitality, and community in one daily experience.
02
Carbon-Zero Ambition
Gensler’s new office needed to support the firm’s 2030 carbon zero goal and push the boundaries of workplace strategy, resilience, and wellness philosophies through design, policy, and program.
03
Downtown Commitment
Maintaining a downtown San Francisco presence was a must as the firm sought to create a more visible platform for clients, employees, and community.
