The San Francisco planning commission is scheduled to vote tomorrow on office floor space authorization for the Flower Mart redevelopment plan at 610-698 Brannan Street in SoMa. The full-block project is expected to completely reshape the property with over two million square feet of new floor area with offices, retail, and POPOS. Kilroy Realty is the owner and project developer.
As reported by The Real Deal in early September, Kilroy is looking to approve 676,800 square feet of office space as required by the 1986-era Proposition. The floor area in question is split relatively evenly between Market Hall and the Gateway.
RIOS is the design architect, James Corner Field Operations is the landscape architect, and Adamson Architect is the executive architect. While design programs will vary across the three structures, the facade material will include curtain walls, precast concrete, granite, and basalt cladding. BKF Engineers will be the civil engineer.
New renderings provide a more detailed insight into the future of the ground-level experience, show more bridges connecting the offices, and preview slight exterior alterations to compensate for floorspace shifted from the Blocks to Gateway Building and Market Hall. The Wholesale Flower Market, once expected to span over a hundred thousand square feet of ground level, is no longer included in the development as the San Francisco Flower Mart Tenants Association opted to move to a new location at 901 16th Street on the border of Potrero Hill and SoMa. The decision to not include the Wholesale Flower Mart was announced last year.
The multi-structure development at 610-698 Brannan Street will produce a total of roughly 2.2 million square feet across 6.6 acres, with 2,025,520 square feet for office use, 30,930 square feet for publicly accessible retail, and 22,690 square feet for child care. The below-grade parking garage will have a capacity for 506 vehicles and 575 bicycles across less than half a million square feet.
The largest building to be built is The Blocks, spanning roughly 1.32 million square feet with a 242-foot tall peak 17 floors high, slightly taller than previously massed. Market Hall will rise 148 feet with 382,120 square feet, and the Gateway Building will top off at 216 feet above street level with 352,880 square feet inside. Proposed office amenities include public events and conference facilities, shared workspace, and exhibition rooms across the project.
The three-structure layout proposed for 610-698 Brannan Street is centered around the Market Alley, a mid-block pedestrian path from 5th street to the Brannan Plaza. The alleyway creates a privately owned public area lined with seating, landscaped parks, and retail between the three structures. There will be 123,240 square feet of usable open space on-site, including 41,230 square feet of POPOS. Records show 71 trees will be added to the site.
James Corner Field will incorporate various native plants and flowers in bright, coordinated displays of color. The flower displays will be integrated into entryway gardens and origami-shaped furniture installations. Each planter will integrate plans that meet certain criteria for the site, including wind resistance, shade tolerance, sun preferences, and watering needs.
Construction is expected to last four and a half years from ground-breaking to completion at a cost of $400 million. The construction job price estimate is not inclusive of the full development cost.
The Planning Commission is scheduled to review plans tomorrow, September 23, at 1 PM. For more information, see the meeting agenda here. The department is expected to approve the office floorspace authorization of 676,800 square feet with conditions based on the staff recommendation.
