New York City, (January 17,2023) – Square Mile Capital Management LLC (“Square Mile Capital”) today announced the closing of a $373 million loan to finance the construction of the first phase of Southline, a mixed-use, transit-oriented life science development in South San Francisco near the city of San Bruno. The senior portion of the loan for the 370,000-square-foot project was provided by Bank OZK.

Southline is being developed by Lane Partners, a commercial real estate investment and development firm headquartered in Menlo Park, CA. Southline’s investment partners include Goldman Sachs Asset Management’s Real Estate group and an affiliate of Beacon Capital Partners.  The financing was arranged by Matt Haden of Eastdil Secured’s San Francisco office.

“We continue to invest into purpose-built lab developments in the strongest life science markets in the country and Southline fits squarely within this objective,” said Square Mile Capital Managing Director Eric Cohen. “We are thrilled to again partner with Bank OZK, as well as affiliates of Goldman Sachs and Beacon, to help create what will be one of the Bay Area’s most prominent new life science projects.”

Southline will become one of the most transformational transit-oriented developments in the Bay Area. Located at 30 Tanforan Avenue in South San Francisco, the 28.5-acre site is adjacent to the San Bruno BART station just south of downtown San Francisco and also near San Francisco International Airport. Southline is adjacent to Highway 101 and near the San Bruno Caltrain and South San Francisco Caltrain Stations, allowing commuters easy access to downtown San Francisco (20-minutes) and San Jose (60-minutes.)

Upon completion, the first phase will feature six stories of state-of-the art lab and office space in addition to a six-story parking garage and amenities such as a fitness center, restaurant, conference facilities and bike storage.
