I'd probably opt for Variant 1 Residential as the clear first choice and then Variant 2 Mixed Use as a second option. Project Commercial and Variant 3 Institutional are too short and don't include any housing.
The specs for Variant 1 Residential:
- Total of 7 buildings from 28-49 floors, 500 ft
- 3,532 residential units
- 100,000 sq ft of retail
- Parking for 1,833 cars and 1,170 bicycles
The specs for Variant 2 Mixed Use:
- Total of 5 buildings from 11-47 floors, 480 ft
- 1,242 residential units
- 1.49 million sq ft of offices
- 100,000 sq ft of retail
- Parking for 1,115 cars and 812 bicycles

Plans Shift For Flower Market Site Redevelopment in SoMa, San Francisco

By: Andrew Nelson 5:30 am on September 16, 2025
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 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.
