The entire space consists of the Atrium, the Holbrook House bar and restaurant, and the sophisticated North Lobby, amounting to nearly 16,000 square feet of usable, rentable event space accommodating up to 2,046 guests.

History Reimagined

Standing for generations as the nerve center of the San Francisco Financial District, The Conservatory's graceful architecture - punctuated by granite-clad 38-foot Doric columns - and unique indoor/outdoor nature makes the venue one of the City's most coveted gathering spaces. Boasting a standing capacity of more than 2,000 guests, on site-access to BART and Muni, and its position just four blocks from Moscone Center, no other San Francisco event facility is so uniquely prepared to host the most complex and important events. The cherry on top? The Conservatory is also the home to the sumptuous and buzzy Holbrook House bar and restaurant, a triumph of design that burst onto the scene in 2023 to universal acclaim.

Thoughtfully reimagined and fully restored in 2023, The Conservatory is a triumph of design, vision, and creative energy. Events are executed with unparalleled professionalism and total discretion, helmed by San Francisco hospitality veterans with deep experience leading marquee properties such as the Julia Morgan Ballroom and the Olympic Club.
