Tehama Grasshopper 431 Tehama St 5,000 SF of Flex Space Available in San Francisco, CA 94103

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. **Highlights** - 5,000+ SF across Floors 2 & 3 — entire upper portion of the building - Two private entrances; secure 24/7 access - Exclusive wraparound rooftop deck with city views - Two bedrooms plus flexible third room / office / sleeping area - Three full bathrooms - Raised marble showroom kitchen with oversized islands - Dramatic open-air atrium, skylights, extra-high ceilings - Radiant heated floors, sculptural staircase, floating fireplace - Multiple open work, lounge, meeting, and gathering areas - Delivered furnished, partially furnished, or unfurnished; FF&E by separate agreement - Fiber-ready and Starlink/satellite-ready - Loading access; one-car parking possible by separate agreement; public garage ~½ block away near 5th & Tehama **Design Pedigree** 2008 AIA Institute Honor Award for Interior Architecture; AIA San Francisco Excellence in Architecture Honor Award; AIA East Bay Exceptional Residential Honor Award; Residential Architect Grand Design Award; 2009 IIDA Northern California Honor Award; 2009 California Home & Design Awards.
