A LEED Platinum Building for the Community

Kilroy’s 333 Brannan project is one of the few ground up construction projects in San Francisco that is not a high-rise; it is uniquely designed to deliver a South of Market appeal while offering all of the advantages of new, green, energy efficient modern design. The 185,000 square foot, 6-story building offers ground floor retail, six levels of office space, and a luscious roof garden. Designed by William McDonough & Partners, the building focuses on efficiency and quality by incorporating an average floor plate size of 31,800 square feet with a design that allows for ample natural light and 100% outside air, ultimately benefitting the occupants with a healthier, modern, sustainable work environment. The exterior combines brick, energy efficient glass, metal and concrete, an architecturally pleasing combination that highlights the front entry on Brannan and the courtyard on Stanford alley.

Located in the bustling and hip SoMa (South of Market) district, 333 Brannan offers too many amenities to name them all, but a few notable ones include: CalTrain Station, The Creamery, MoMo’s, Paragon, Supper Club, Fingale, 25 Lusk, Lucky Strike and AT&T Park. The vibe of SoMa is 24/7. It is a live/work/play neighborhood where visions become a reality in the San Francisco technology hub.


“CarbonCure concrete looks and performs as well as traditional concrete with no additional cost; the only difference is that you can feel proud about the reduction in the carbon footprint. The CarbonCure team was a pleasure to work with, very accessible, flexible, and quick to respond.”

Proudly Supporting CarbonCure

According to Sara Neff, Vice President of Sustainability at Kilroy Realty, “The biggest advice I can give about minimizing costs is to bake in LEED upfront. You have to be clear on your expectations with the design team.  It’s a matter of planning early and getting the requirements into the specs early. We don’t believe LEED Gold has to come at a premium.”

The addition of concrete masonry units with sequestered CO₂ was an easy decision for Kilroy as it represented a cost-effective solution for reducing the carbon footprint of the building’s concrete materials, which aligns with Kilroy’s corporate sustainability goals.
