F4 Transbay Partners LLC has revised its development plans for a project at 542-550 Howard St. in San Francisco. The JV of Hines, Urban Pacific Development and Broad Street Principal Investments, an affiliate of Goldman Sachs, plans to build a mixed-use development at Transbay Parcel F, which is next to Salesforce Tower. The JV originally purchased the parcel for $160M in 2016.

The resubmitted plans follow a yearlong planning and design effort that was done with close coordination with the city of San Francisco. The current project maintains the original vision for a vertical mixed-use community. The 61-story, 800-foot tower will have 251K SF of Class-A office space, a 210-room luxury hotel, 170 residential units, 79K SF of shared amenity space and over 9K SF of retail.

The new design includes a through-block pedestrian passageway connecting Howard and Natoma streets, a public elevator connection to the Salesforce Transit Center rooftop park via a fifth-floor skybridge and over 10K SF of public open space. A hotel flag for the project is expected to be announced in the coming months.

Parcel F is the last remaining site available for development of a supertall building in downtown San Francisco, and one of only three projects that features a direct public connection to the rooftop park at the transit center.

Once completed, Parcel F will be the fourth-tallest building in San Francisco and the only mixed-use project to include residential, office, hotel and retail uses in a single tower. The project is being designed by Pelli Clarke Pelli Architects in partnership with HKS Architects, acting as architect of record.
