As we wrote about the recently completed six-story office building at 505 Brannan Street, which is now home to Pinterest, prior to it breaking ground in 2016:

“Speaking of development along San Francisco’s emergent Fourth Street Transit spine, while the City’s Central SoMa Plan envisions up-zoning the southwest corner of Brannan and Fourth to allow a tower of up to 250-feet to rise on the site, TMG Partners appears to be moving forward with plans to build a six-story building on a large portion of the parcel, behind the squat Bank of America building which shares the lot and will remain in place (as will K&L Wines).”

And yes, with the possibility of San Francisco’s Central SoMa Plan being approved by Planning at the end of this month, and plans for a 250-foot-tall tower to rise on the aforementioned K&L Wines site having been drawn, plans to add another eleven (11) stories atop the brand new building at 505 Brannan are now in the works as well.

As designed by Heller Manus, the proposed addition would rise to a height of 240 feet upon the building’s existing foundation (which was designed with the expansion in mind) and add another 165,000 square feet of office space to the development, for a total of 294,450, while maintaining the existing café fronting Brannan Street and the building’s underground garage for 68 cars.
