As we celebrate the grand opening of the new Stockton City Hall, Indigo | Hammond + Playle Architects is proud to have helped realize this landmark urban renewal project. By embracing adaptive reuse, the City of Stockton transformed an existing footprint into a vibrant civic hub, dramatically reducing embodied carbon while delivering a cost-effective, modernized facility for the community.
For over 25 years, Indigo has been the premier sustainability architect in the Central Valley. We know how to actually get things built in today’s complex regulatory environment. Our civic clients trust us because we can deliver ultra-efficient, Zero Net Energy (ZNE) and LEED-certified buildings — without the premium price tag. In fact, our leadership in passive design is why the State of California relies on Indigo to advise the Department of General Services on ZNE building initiatives.
Our heritage of environmental stewardship and resilience is visible across Northern California’s public sector. Beyond Stockton, our diverse, technically skilled team designed the ZNE Vacaville Intermodal Transit Center as well as the Dublin Public Safety Center, which proudly stands as the first LEED Platinum renovation project in the United States.
We design resilient places for a changing world. By integrating nature-based principles, our buildings harness abundant free resources — sunlight, fresh air and thermal mass — to reduce reliance on oversized HVAC systems, lower long-term operational costs and improve the health and productivity of municipal staff.
At Indigo, you receive hands-on, principal-level service at every step. We evaluate your specific goals, recommend the most effective delivery methods and ensure your project is buildable and affordable. Whether executing a complex adaptive reuse or a ground-up zero-energy facility, Indigo creates climate-adapted, beautiful civic spaces that serve your community today and stand resilient for tomorrow.
Our mission is to integrateart, architecture and ecology.
Grounded in valley design, we leverage Zero Net Energy, LEED standards and adaptive reuse in order to put people in touch with their environment, each other and their spiritual and cultural aspirations.
