Just under two years after its groundbreaking, the office building at 555 Mission St. in the burgeoning Mission Street Corridor of San Francisco’s South Financial District has reached completion. Acting on behalf of Tishman Speyer, owner of the 670,000-square-foot tower, general contractor Turner Construction hammered in the last nail right on schedule, marking the debut of the first Class A office building to be developed in San Francisco in the last four years. Stretching 33 stories high, 555 Mission (pictured) also features 3,400 square feet of ground-level retail space, an 11,000-square-foot plaza and a two-story below grade parking facility. Some of 555 Mission’s office space was claimed in advance, including an 83,000-square-foot chunk that DLA Piper pre-leased during the second quarter; a 60,000-square-foot space that law firm Gibson Dunn & Crutcher L.L.P. signed on for in March of this year, and the entire 15,000 square-foot top floor, which will be home to Sequoia Capital. Originally, 555 Mission was not conceived as a model for sustainable development, but Tishman Speyer decided to go green several months into the project. Designed by Kohn Pederson & Fox in conjunction with Heller Manus Architects, the building incorporates elements that adhere to LEED Silver certification standards, including a minimum 10 percent of recycled construction materials, paints and sealants that meet volatile organic compounds requirements, and a reflective roof. Achieving LEED Silver status will put 555 Mission ahead of the green game, so to speak. In August, San Francisco Mayor Gavin Newsom signed a landmark green building ordinance that requires new commercial and residential construction to meet high levels of LEED and green building certifications. The ordinance put San Francisco at the top of the list of U.S. cities with the strictest green building guidelines. Headquartered in New York City, Tishman Speyer is one of the world’s top owners, developers, operators and fund managers of Class A real estate. The company has managed assets totaling 113 million square feet in major metropolitan markets throughout the U.S., Europe, Latin America and Asia.
