What Grain Construction does
Grain Construction is a private, founder-led custom general contractor headquartered at 1700 Octavia St. in San Francisco, California, with stated operations across the Bay Area and Los Angeles. Founded by Barrett Karber, the firm delivers luxury residential construction including ground-up custom homes and full-gut renovations, hospitality buildouts for hotels, guest houses, cafes, and restaurants, and select commercial projects such as offices and retail spaces. Core technology and methodology center on lean construction practices, creative problem-solving, and an emphasis on technical perfection and architecturally-driven design, supported by a proprietary client communication app that provides real-time project updates and direct messaging with the build team.
The firm maintains an integrated custom furniture capability marketed under the dba+shop sub-brand, producing tables, benches, credenzas, and architectural hardware such as the Heritage Table, Silo Table, Teff Tables, Barley Bench, Credenza for Hotel Healdsburg, and the Chimney Rock door handle. Customer segments split between high-net-worth private clients, architects (notably Studio Plow and David Baker Architects), interior designers, hospitality operators (Saint Frank Coffee, Mr. Holmes Bakehouse, Harmon Guest House, Hotel Healdsburg), and commercial tenants. Revenue is generated through one-time project-based professional services fees, with pricing project-specific and quote-based and no public pricing disclosure.
Distribution is direct: Grain engages private clients, interior designers, and architects through consultations and referrals rather than intermediaries, amplified by a portfolio-driven website, organic social presence on Instagram, Facebook, and LinkedIn, and earned media placements in Vogue Living, AD France, ELLE Decoration UK, Wallpaper, House Beautiful, and Design Milk. The company holds California contractor license #1080500 and operates without disclosed external institutional investors.
