Formerly known as 199 Fremont, the transformation of the property will mark a new chapter aimed at attracting leading innovation tenants to San Francisco’s emerging ‘AI Alley’
SAN FRANCISCO, CA – April 22, 2025 – DivcoWest, a DivCore Capital company and vertically-integrated commercial real estate investment firm, is proud to announce a joint venture with funds affiliated with Blackstone Real Estate (“Blackstone”) to reposition 300 Howard Street, a prominent 25-story office tower in San Francisco’s vibrant South Financial District. As part of the agreement, Blackstone has acquired a joint-control interest in the property.
Previously known as 199 Fremont, the 420,000 square foot tower has been reimagined to embrace its location within ‘AI Alley,’ where a growing wave of tech and AI companies are redefining the area. The transformation of 300 Howard is in motion, reimagining the early-2000s tower into a high-performance hub built for today’s most ambitious teams. DivcoWest and Blackstone are rolling out a repositioning strategy with hospitality-inspired upgrades designed to fuel connection, creativity, and next-gen workplace experiences. A full floor of dedicated tenant amenities will anchor the building, featuring a cutting-edge conference center, elevated lounge spaces, and top-tier fitness and wellness facilities—all tailored to meet the demands of San Francisco’s innovation economy.
“We’re excited to embark on a long-term partnership with Blackstone in this venture, as 300 Howard sits at the heart of one of the most innovative commercial corridors in the country,” said Gregg Walker, President of DivcoWest Real Estate Asset Management. “Together, we’re making a bold investment to reimagine the building as a next-generation workplace—one that inspires, attracts, and empowers the talent driving the future of AI and technology.”
David Levine, Co-Head of Americas Acquisitions for Blackstone Real Estate, said: “We are big long-term believers in San Francisco and are thrilled to partner with DivcoWest as we reposition this Class A office tower located in a prime submarket of the city.”
JLL will continue its partnership with ownership, playing a key role in the office leasing strategy to attract top-tier tenants to 300 Howard. JLL Executive Managing Director Chris Roeder, Senior Managing Director Ted Davies, and Senior Vice President Carlye Parker will be the exclusive office leasing agents for the property.
“We look forward to working closely with DivcoWest and Blackstone to reintroduce 300 Howard as a premier asset for innovative tenants,” said Chris Roeder, Executive Managing Director at JLL. “With flexible floorplates, Bay views, exceptional amenities, and prime South Financial District location, it’s ideal for companies looking to grow and attract top talent. As one of the few full building opportunities in the market, 300 Howard offers a unique chance to establish a global headquarters in the heart of San Francisco.”
The team is also partnering with Alex Sagues, Senior Vice President at CBRE, to reintroduce the iconic Town Hall space located steps from 300 Howard as a dynamic culinary destination. With top-tier local restaurant groups under consideration, the space is poised to become a neighborhood anchor and go-to gathering spot for the community.
Notably, 300 Howard sits directly alongside Salesforce Park—a five-acre urban oasis spanning four city blocks, complete with a half-mile walking loop and a lush ‘green roof’ atop the Salesforce Transit Center. Often dubbed San Francisco’s ‘Grand Central of the West,’ the Transit Center is a major regional transit hub, connecting employees to the city and beyond with seamless access to bus and light rail lines in every direction.
