1 Ecker is sustainable down to its very foundation. The original century-old building structure was painstakingly restored and updated with brand-new modern interior fixtures and finishes, with every effort made to use existing materials. The soaring arched windows are 100% recycled, and the building’s sustainable interiors feature Energy Star® appliances and bamboo flooring. Multiple Zipcar® locations are within walking distance for pay-as-you-go car convenience, and the future Transbay Transit Center steps away at 1st and Mission Streets will house 11 transportation systems, including AC Transit, BART, Caltrain, Muni & Amtrak, for easy access to all of the Bay Area and beyond.
