431 Tehama St
San Francisco, CA 94103 SoMa

A rare opportunity to lease the upper floors of Tehama Grasshopper, the AIA Institute Honor Award–winning SoMa warehouse conversion by Fougeron Architecture. Over 5,000 SF across two floors, this private, self-contained live/work headquarters has previously served as a private HQ and residence for prominent technology and entertainment figures — and it is unlike anything else available in San Francisco.
This is not conventional office space. It is an architectural environment: a dramatic open-air atrium, skylights throughout, extra-high ceilings, radiant heated floors, a sculptural staircase, a floating fireplace, and a raised marble showroom kitchen with oversized islands at the center of the plan. Two private entrances and secure 24/7 access keep the space fully self-contained. The exclusive wraparound rooftop deck — private to this suite — offers a rare outdoor amenity for executive meetings, team gatherings, and private entertaining in the heart of SoMa.
