333 Brannan San Francisco, California


Using the Cradle to Cradle® design framework, William McDonough + Partners designed Dropbox’s new home at 333 Brannan to be resource effective, support human and ecological health, and respect the neighborhood’s historic aesthetic. The building achieved LEED® Platinum certification; focusing on effectiveness and quality with a design that allows for ample natural light and 100% outside air. The exterior front entry on Brannan and the courtyard on the Stanford alley combine brick, energy efficient glass, metal, and concrete for historical and industrial neighborhood harmony.

Employing eco-district strategies, the building is part of an urban micro grid that shares electrical energy, heating, and cooling between neighboring buildings. Integrated photovoltaics on the roof supply a portion of the building’s energy needs and are expected to reduce energy usage by 26%. On-site water capture and reuse reduces potable water demand by an expected 45%, and landscaped courtyards are planted with native drought resistant species.

333 Brannan is located in the bustling and burgeoning South of Market district in San Francisco, an area that is becoming a vibrant hub for a live, work, and play lifestyle with its close proximity to restaurants, AT&T Park, the CalTrain station, Muni and new businesses. William McDonough + Partners designed the facility to accommodate alternative mobility options including bike racks, an on-site car share program, and electric vehicle charging stations.
