MOUNTAIN VIEW, CA-Google, Inc. has signed a long-term office lease at the former Mayfield Mall here.

The property's owner is a joint venture between Rockwood Capital, LLC and Four Corners Properties, LLC. The renovation to transform the property into a premier class “A” Silicon Valley office campus has begun, with completion planned for 2014. The campus, located at 100 Mayfield Avenue, will consist of more than 500,000 square feet of office space on 27.6 acres, and this is the largest lease signed in Silicon Valley this year.

The property was constructed in 1966 as the Mayfield Mall, which was the first enclosed air-conditioned shopping mall in northern California. The Mayfield Mall was occupied by businesses including J.C. Penney, Wells Fargo Bank, the Mayfair Market grocery store, many smaller local shops, and a Greyhound bus terminal. The renovated buildings will incorporate historic elements from the property's previous retail use into a modern state-of–the-art office campus. Among its features will be dramatic multi-story sky-lit atriums, LEED building certification, outdoor congregation and amenity areas, gyms, abundant bike storage, and recycled outdoor furniture constructed from existing trees on the property. The campus is located in the heart of Silicon Valley in a mixed-use area with shops, restaurants, housing, and a planned hotel nearby. It is adjacent to the San Antonio Caltrain station, a 50-minute train ride to downtown San Francisco.
