Big Central SoMa Project Positioning to Break Ground Next Year
February 6, 2020

The proposed mass redevelopment of 12 contiguous Central SoMa parcels stretching from 400 Second Street to 665 Harrison, a.k.a. the One Vassar project, has just qualified for a streamlined environmental review and could break ground as early as next year if approved, with two towers rising up to 350 feet in height and a modern addition atop the historic building between.



As designed by Skidmore Owings & Merrill (SOM), the refined plans for the 400 Second Street tower would now yield 446,000 square feet of office space, with 5,100 square feet of ground floor retail space, a basement garage for 198 cars and 6,300 square feet of privately-owned public open space (POPOS) fronting Second Street, half of which would be enclosed.

On the other end of the site at 657 Harrison Street, a 35-story residential tower designed by Solomon Cordwell Buenz (SCB) would yield up to 489 apartments, with a 14,000-square-foot childcare facility, 1,700 square feet of ground floor retail space and a basement garage for 128 cars.

And atop the historic building at 645 Harrison Street, a modern 15-story addition designed by SOM would rise to a height of 200 feet and yield a new 468-room hotel.

. . . the first floor of the existing 4-story building at 645 Harrison Street would be converted into 24,000 square feet of new restaurant and retail space, configured as a “market hall,” with 65,000 square feet of office space, and 44,000 square feet of PDR, spread across the floors above and an adjacent 8,400-square-foot Hawthorne Street Plaza connecting Harrison and Perry.

. . . the project team is touting the potential for breaking ground for the two towers in mid-2021, with the redevelopment of 645 Harrison Street beginning in mid-2022 and the entire development completed by late 2024. But the project team will need to secure an increasingly scarce office allocation . . . .
