While SKS Partners and the Prado Group have been pushing forward with plans to redevelop the 10-acre Laurel Heights campus at 3333 California Street, which it has acquired from UCSF, a bid to block or delay the project has been made.

As proposed by the Laurel Heights Partners project team, portions of the existing 455,000-square-foot office building on the site would be demolished, the remainder of the central building would be split in two, expanded by two floors, remodeled and repurposed, and 13 new buildings, including 7 duplexes fronting Laurel Street, would rise up to six stories in height across the campus site.

The proposed redevelopment would yield 558 residential units; 49,999 square feet of office space; 54,000 square feet of retail space; a new 15,000 square foot child care center; parking for 895 cars (and 693 bikes); and 236,000 square feet of open space, including the Masonic Plaza as newly rendered below.

And as currently envisioned, the project would be constructed in four overlapping phases over the course of seven years, with the first phase breaking ground in 2020 if the entitlements to proceed are secured.

All that being said, the Laurel Height Improvement Association (LHIA) has now formally nominated the existing modernist building and campus on the 3333 California Street site, which was originally developed for the Fireman’s Fund Insurance Company circa 1957, to be listed on the National Register of Historic Places.

While the project team has formally objected, according to a draft finding prepared for a hearing next week, San Francisco’s Historic Preservation Commission is expected to support the nomination, as “an important example of a suburban corporate property type adapted to an urban setting in San Francisco,” “the embodiment of postwar decentralization and suburbanization of San Francisco,” “an example of a corporate headquarters in San Francisco that reflects midtwentieth-century modernist design principles,” and for “its association with the master engineer, John J. Gould & H. J. Degenkolb, and the master landscape architecture firm of Eckbo, Royston, & Williams.”

We’ll keep you posted and plugged-in.
