William McDonough-Designed Brick and Concrete Building at 333 Brannan Street Mixes Historical Character with Cutting-Edge Sustainability

SAN FRANCISCO, CA, December [19], 2013 – Kilroy Realty Corporation (KRC:NYSE) launched its second ground-up development project in downtown San Francisco today with a ground-breaking ceremony that featured Mayor Ed Lee and architect David Johnson with William McDonough + Partners, a key creative force behind the LEED® Platinum- designed, six-story brick and concrete office property located at 333 Brannan Street in the SOMA District. The event was hosted by KRC chairman, president and CEO John Kilroy, Jr.

“333 Brannan Street will create another dynamic work place in San Francisco where companies can continue to innovate, thrive and grow jobs right here in the Innovation Capital of the World,” said Mayor Ed Lee. “The construction of this new office complex demonstrates yet again that investors have confidence in our City, and I thank Kilroy for continuing to partner with us to keep our economy growing and to keep our job numbers rising.” Located amid buildings dating from the city’s brick-and-timber industrial past, 333 Brannan Street features an exterior that fits gracefully with its neighborhood’s roots as well as efficient, expansive interiors designed for a contemporary workforce.

Among the most significant attributes of the William McDonough + Partners design are the many advances in sustainable development and property operation it incorporates. These include onsite power generation capabilities and a rainwater reclamation system expected to reduce energy usage by approximately 26% and water usage by 45% compared to a typical building of its size. “The site is one of the city’s first to employ eco-district strategies and reflects Kilroy Realty’s progressive, long term view and understanding of building designs, and we believe that this project will raise the standards for future development,” said architect David Johnson.

333 Brannan Street’s large, open floor plates, abundant natural light and operable windows delivering 100% fresh air all create a work environment that will be highly appealing for the technology and media companies that predominate in the South of Market area. The building will also feature an onsite restaurant, ground floor retail amenities, and a large roof top garden common area.

“The transformation now taking place in commercial real estate design is profound and San Francisco is at the leading edge with KRC commencing construction on the second LEED Platinum ground up development after 350 Mission Street,” said John Kilroy, Jr., KRC’s chairman, president and CEO. “Working with creative partners like William McDonough + Partners and with a supportive city leadership, KRC is committed to developing properties like 333 Brannan Street that are aesthetically appealing, environmentally innovative and deliver dynamic work environments essential to attracting and retaining employees.”

With the start of 333 Brannan Street, KRC now has more than 1.8 million square feet of office space under construction and 2.7 million square feet of operating properties in the San Francisco Bay Area. The company is currently building three new corporate campuses for technology giants,, LinkedIn and Synopsys. Recently in November, KRC also commenced construction on Crossing/900, a two building office campus in Redwood City.
