Kilroy looking to add 677k sf of office space to massive Flower Mart redevelopment

Kilroy Realty is seeking approval to add 676,801 square feet of office space to its planned redevelopment of the San Francisco Flower Mart at 610-698 Brannan Street.

The firm is seeking exemptions to Proposition M, a 1986 rule that caps the amount of office space approved in the city.

Current plans for the site call for three mixed-use buildings with a total of 2,061,380 square feet of office space, 47,568 square feet of retail, 41,229 square feet of privately owned public open space, 22,690 square feet for a child care facility and 950 square feet for a community facility, according to a public notice from the San Francisco Planning Department. The three buildings — called The Blocks (East and West), Market Hall and Gateway— are planned as a 2,132,605-square-foot development that extends from the corner of Brannan Street and Fifth Street.

The additional Prop M space will be split between the Market Hall and Gateway buildings. The Market Hall site is currently proposed as an eight-story building that spans 382,124 square feet. Kilroy is looking to add 323,925 square feet of office space to the property. The Gateway Building, meanwhile, is planned as a 16-story building with 352,876 square feet of space. An additional 352,876 square feet of office space is proposed for the site.

Kilroy has also cut a large portion of the retail space for the site. According to an April report from YIMBY, a total of 204,170 square feet of retail was planned for the project. The current version of the plan has less than a quarter of that total.

Kilroy also is planning a reshuffle of the square footage for the site. According to amended plans for the project, the firm is chopping off 58,199 square feet of space between the two Blocks buildings for the purpose of separating the two properties. A total of 58,198 square feet will also be transferred from the Blocks buildings to the Market Hall retail mezzanine and the Gateway Building.

The Planning Commission approved the office allocation for the first phase of the project in July of 2019. The agency will vote on the exemption during a hearing scheduled for September 23.

Kilroy reportedly acquired the site for $87.2 million in 2016. Construction is expected to last more than four years.

Kilroy recently sold a Mission Bay office complex leased to Dropbox for over $1 billion. The purchase price stands as the second-highest for a single property in the city’s history. The firm’s San Francisco holdings also include Kilroy Oyster Point at 384 Oyster Point Boulevard and 100 First Street in SoMa.

The firm did not respond to a request for comment.
