Updated plans have been filed for the redevelopment of the former Flower Market site at 610 Brannan Street in SoMa, San Francisco. The application considers four potential scenarios, ranging from offices to housing a few blocks away from the San Francisco Caltrain Station. The Los Angeles-based Kilroy Realty is the project developer.
The four project variants by Kilroy are labeled Commercial, Residential, Mixed-use, and Institutional.

The commercial iteration aims to develop 2.6 million square feet of office space across five structures, comprising 100,000 square feet of retail, 300,000 square feet of institutional space, and 332,900 square feet of parking. Buildings will rise between 11 and 18 floors, reaching a maximum height of 270 feet.
The institutional variant would include 1.38 million square feet for institutional or medical uses, 1.27 million square feet of office space, 100,000 square feet of retail, and 330,880 square feet for parking. Similar to the commercial version, this would include five structures ranging in height from 11 to 18 floors.
The residential variant could add 3,532 apartments across seven buildings, the tallest of which could be 500 feet tall. The project could be a high-density block averaging roughly 535 units per acre. The mixed-use iteration would include five buildings rising between 11 and 47 floors, with 1,242 units, 1.49 million square feet of offices, 100,000 square feet of retail, and 432,520 square feet for parking.

The four different visions brought forward by Kilroy illustrate how confidence in San Francisco’s economic recovery has significantly improved, but questions remain about how the demand will materialize.
Kilroy recently completed construction of the new permanent home for the Wholesale Flower Market at 901 16th Street. The market relocated to the Potrero Hill space at the beginning of this year.
The project is anticipated to cost around $500 million, an estimated figure not inclusive of all development costs. According to the application, construction is anticipated to start as early as 2027.

7 buildings up to 500′ — YES PLEASE
SF need more HEIGHT. I’m sick of all the 3-4 story buildings in this area.
If this is built SF needs to seriously rework the pedestrian environment for a good 2-3 blocks around this block. Many more trees, wider sidewalks and more pedestrian crossings and bike connections. Similar to all the new buildings in the East Cut which used to resemble this area and now feels like a proper district, not leftover space with some high rises.
All or partially residential please!
Totally agree with the comment to widen sidewalks and plant trees, this are used to be industrial so they needed wide multi lane streets without overhanging branches. Moving to residential and offices, you need safe wide sidewalks with calm, slow traffic. Have lived at 2nd and King for 19 years- it’s marginally better once they widened 2nd street but all the East-west streets need to have the same treatment. They’re still freeway on ramps/off ramps and not residential streets.
