Kilroy Realty Corporation (NYSE: KRC) will boost its Bay Area construction pipeline to more than 1.8 million square feet with new office-project starts in downtown Redwood City and the brick and timber commercial neighborhood of Brannan Street in the city's booming SOMA district. More than 1.3 million square feet of the company's Bay Area construction pipeline is pre-leased.

Crossing/900. KRC held a groundbreaking ceremony last week for this two-building, mid-rise office campus located in Redwood City's increasingly urbanized downtown area. The new 300,000-square-foot project is located steps away from the city's Caltrain station and conveniently close to the two major freeways serving the region and San Francisco International Airport. It is also within walking distance of abundant retail, dining and entertainment amenities as well as over a thousand residential units under construction. The project, designed by Korth Sunseri Hagey, represents a key component in the city's plan to attract new businesses and residents to the downtown area and expand its role as a major employment and residential hub in the Silicon Valley.

Crossing/900 is a LEED Gold certified development project that will feature large open floor plates, forward-looking designs, outdoor plaza areas, abundant parking and up-sized base building features thereby allowing greater densities that are highly desirable among today's modern workforce. "The project will serve the burgeoning knowledge-based industries in this region that currently has very limited options for new office space, especially near Caltrain," said Mike Sanford, KRC's Senior Vice President, Northern California. KRC expects to complete construction on the project in 2015.

333 Brannan Street. Earlier this month, KRC received site approval for the construction of a modern 170,000-square-foot, six-level, brick and concrete office building at this 0.82-acre site located in one of San Francisco's most popular technology and media corridors. Designed by William McDonough, a leading proponent of sustainable architecture, 333 Brannan Street will be a LEED Platinum+ certified project and one of the most eco-friendly, greater than two-story office buildings built to-date in California. The building capitalizes on the charm of the historical area with contemporary and state of the art sustainable features, including large, highly efficient floor plates designed for higher density users, expansive public spaces, a panoramic roof deck and an on-site restaurant. 333 Brannan is surrounded by dozens of cafes and restaurants, is in close proximity to AT&T Park, Caltrain, and BART, and is also adjacent to KRC's 250 Brannan Street and 301 Brannan Street properties. The company expects to complete construction on the project in 2015.

With these two starts, KRC has now expanded its Bay Area construction portfolio by nearly 500,000 square feet. The company is also currently building new corporate campuses for LinkedIn and Synopsys in the Silicon Valley, and a new office tower at 350 Mission Street in downtown San Francisco for Salesforce.com. KRC recently completed an 88,000-square-foot office project for Audience Inc. in Mountain View.

"The transformation that has taken place over the past several years in the way tenants use office space and the recognition that location and quality of the environment is essential in attracting and retaining employees is profound. Just as we have transformed our core portfolio with the assets we've acquired and renovated where appropriate, we are focused on developing market leading facilities," said John Kilroy, Jr., KRC's chairman, president and CEO.
